126-432: The Gladstone Branch (also known as the Gladstone Line ) is a commuter rail line operated by NJ Transit in the U.S. state of New Jersey , one of two branches of the Morris & Essex Lines . Gladstone Line trains operate between Gladstone station and either Hoboken Terminal or New York Penn Station . The Gladstone Branch itself runs from Gladstone to a junction with the Morris & Essex at Summit. It

252-471: A consist respond in the same way to throttle position. Binary encoding also helps to minimize the number of trainlines (electrical connections) that are required to pass signals from unit to unit. For example, only four trainlines are required to encode all possible throttle positions if there are up to 14 stages of throttling. North American locomotives, such as those built by EMD or General Electric , have eight throttle positions or "notches" as well as

378-429: A "reverser" to allow them to operate bi-directionally. Many UK-built locomotives have a ten-position throttle. The power positions are often referred to by locomotive crews depending upon the throttle setting, such as "run 3" or "notch 3". In older locomotives, the throttle mechanism was ratcheted so that it was not possible to advance more than one power position at a time. The engine driver could not, for example, pull

504-459: A 4-way intersection of Central Avenue and Livingston Avenue. This crossing is one of the few 4-way crossings along NJ Transit rail lines. The line then continues, crossing Foley Place and entering Murray Hill station . At Murray Hill, the track splits in two to allow eastbound trains and westbound to pass each other, since most of the line is single tracked. There is a wooden plank at Murray Hill to allow passengers on westbound trains to get off before

630-609: A Rational Heat Motor ). However, the large size and poor power-to-weight ratio of early diesel engines made them unsuitable for propelling land-based vehicles. Therefore, the engine's potential as a railroad prime mover was not initially recognized. This changed as research and development reduced the size and weight of the engine. In 1906, Rudolf Diesel, Adolf Klose and the steam and diesel engine manufacturer Gebrüder Sulzer founded Diesel-Sulzer-Klose GmbH to manufacture diesel-powered locomotives. Sulzer had been manufacturing diesel engines since 1898. The Prussian State Railways ordered

756-651: A city's central business district, and often share right-of-way with intercity or freight trains. Some services operate only during peak hours and others use fewer departures during off peak hours and weekends. Average speeds are high, often 50 km/h (30 mph) or higher. These higher speeds better serve the longer distances involved. Some services include express services which skip some stations in order to run faster and separate longer distance riders from short-distance ones. The general range of commuter trains' travel distance varies between 15 and 200 km (10 and 125 miles), but longer distances can be covered when

882-583: A diesel locomotive from the company in 1909, and after test runs between Winterthur and Romanshorn , Switzerland, the diesel–mechanical locomotive was delivered in Berlin in September 1912. The world's first diesel-powered locomotive was operated in the summer of 1912 on the same line from Winterthur but was not a commercial success. During test runs in 1913 several problems were found. The outbreak of World War I in 1914 prevented all further trials. The locomotive weight

1008-499: A diesel-driven charging circuit. ALCO acquired the McIntosh & Seymour Engine Company in 1929 and entered series production of 300 hp (220 kW) and 600 hp (450 kW) single-cab switcher units in 1931. ALCO would be the pre-eminent builder of switch engines through the mid-1930s and would adapt the basic switcher design to produce versatile and highly successful, albeit relatively low powered, road locomotives. GM, seeing

1134-465: A flashover (also known as an arc fault ), which could result in immediate generator failure and, in some cases, start an engine room fire. Current North American practice is for four axles for high-speed passenger or "time" freight, or for six axles for lower-speed or "manifest" freight. The most modern units on "time" freight service tend to have six axles underneath the frame. Unlike those in "manifest" service, "time" freight units will have only four of

1260-564: A freight house to the west. Just west of the station near the freight house, the track splits in two again to allow eastbound and westbound trains to pass each other. After Far Hills, the line snakes through the Far Hills area before entering the borough of Peapack and Gladstone while crossing over the North Branch Raritan River and under Peapack Road. Peapack station is next at the crossing at Holland Avenue. The line then crosses

1386-413: A headway rather than a published timetable and use dedicated tracks (underground or elevated), whereas commuter rail often shares tracks, technology and the legal framework within mainline railway systems, and uses rolling stocks with more seating and higher speed for comfort on longer city-suburban journeys. However, the classification as a metro or rapid rail can be difficult as both may typically cover

1512-566: A locomotive. Internal combustion engines only operate efficiently within a limited power band , and while low-power gasoline engines could be coupled to mechanical transmissions , the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard 2.5 m (8 ft 2 in)-wide locomotive frame, or would wear too quickly to be useful. The first successful diesel engines used diesel–electric transmissions , and by 1925

1638-560: A major manufacturer of diesel engines for marine and stationary applications, in 1930. Supported by the General Motors Research Division, GM's Winton Engine Corporation sought to develop diesel engines suitable for high-speed mobile use. The first milestone in that effort was delivery in early 1934 of the Winton 201A, a two-stroke , mechanically aspirated , uniflow-scavenged , unit-injected diesel engine that could deliver

1764-577: A metropolitan area exclusively, run on separate tracks in the centre, and often feature purpose-built rolling stock. The fact that the terminology is not standardised across countries (even across English-speaking countries) further complicates matters. This distinction is most easily made when there are two (or more) systems such as New York's subway and the LIRR and Metro-North Railroad , Paris' Métro and RER along with Transilien , Washington D.C.'s Metro along with its MARC and VRE , London's tube lines of

1890-421: A prototype diesel–electric locomotive for "special uses" (such as for runs where water for steam locomotives was scarce) using electrical equipment from Westinghouse Electric Company . Its twin-engine design was not successful, and the unit was scrapped after a short testing and demonstration period. Industry sources were beginning to suggest "the outstanding advantages of this new form of motive power". In 1929,

2016-477: A real prospect with existing diesel technology. Before diesel power could make inroads into mainline service, the limitations of diesel engines circa 1930 – low power-to-weight ratios and narrow output range – had to be overcome. A major effort to overcome those limitations was launched by General Motors after they moved into the diesel field with their acquisition of the Winton Engine Company ,

2142-580: A shuttle train operated every two hours between Newark Broad Street and Hoboken Terminal . (This shuttle train was later extended to provide bihourly service to Bay Street on the Montclair-Boonton Line ). Passengers for Penn Station connect at Summit to/from a Dover/Penn Station train. The line is colored pale green on system maps and its symbol is a horse, a reference to the Grand National Hurdle Stakes steeplechase race held in

2268-551: A siding for parking equipment. The line then continues and crosses the Passaic River a second time and enters Morris County. There are three stations in Long Hill Township . The first is Gillette station . After Gillette, the line crosses Morristown Road and enters Stirling station . At Stirling, the track splits in two, again to allow eastbound and westbound trains to pass each other. The line also crosses Central Avenue at

2394-748: A small number of diesel locomotives of 600 hp (450 kW) were in service in the United States. In 1930, Armstrong Whitworth of the United Kingdom delivered two 1,200 hp (890 kW) locomotives using Sulzer -designed engines to Buenos Aires Great Southern Railway of Argentina. In 1933, diesel–electric technology developed by Maybach was used to propel the DRG Class SVT 877 , a high-speed intercity two-car set, and went into series production with other streamlined car sets in Germany starting in 1935. In

2520-417: A small number of reverse peak trains. On weekends the line operates Gladstone-Summit service hourly along the branch. Until August 13, 2006 all trains continued to Hoboken. On that date, service between Hoboken and Summit was cut back to once every two hours on weekends. On May 11, 2008, off-peak weekday Hoboken-Dover trains (600 Series) were cut. In addition, weekend Gladstone trains were cut back to Summit, and

2646-506: A walkway in Liberty Park before entering Gladstone yard. At Gladstone yard, the track splits into 5 to allow for parking of trains. One of the tracks switches back to condense into one or can act as a siding, while the other 4 tracks condense back into one. West of the yard, the tracks enter Gladstone station and its freight house. One track leads to the freight house, while two lead to the station. The timetables are arranged so that most of

2772-533: Is better able to cope with overload conditions that often destroyed the older types of motors. A diesel–electric locomotive's power output is independent of road speed, as long as the unit's generator current and voltage limits are not exceeded. Therefore, the unit's ability to develop tractive effort (also referred to as drawbar pull or tractive force , which is what actually propels the train) will tend to inversely vary with speed within these limits. (See power curve below). Maintaining acceptable operating parameters

2898-874: Is especially the case for lines operated by Korail , such as the Gyeongui-Jungang Line , the Gyeongchun Line , the Suin-Bundang Line , or the Gyeonggang Line . Even some lines not operated by Korail, such as the AREX Line, the Seohae Line or the Shinbundang Line mostly function as commuter rail. Lastly, even for the "numbered lines" (1–9) of the Seoul Metropolitan Subway which mostly travel in

3024-502: Is generally limited to low-powered, low-speed shunting (switching) locomotives, lightweight multiple units and self-propelled railcars . The mechanical transmissions used for railroad propulsion are generally more complex and much more robust than standard-road versions. There is usually a fluid coupling interposed between the engine and gearbox, and the gearbox is often of the epicyclic (planetary) type to permit shifting while under load. Various systems have been devised to minimise

3150-591: Is heavily used by commuters in the Greater Tokyo Area , who commute between 100 and 200 km (62 and 124 mi) by Shinkansen . To meet the demand of commuters, JR sells commuter discount passes. Before 2021, they operated 16-car bilevel E4 Series Shinkansen trains at rush hour, providing a capacity of 1,600 seats. Several lines in China, such as the Beijing–Tianjin Intercity Railway and

3276-565: Is located north of New Providence on the Morristown Line, between the Summit and Chatham stations, and receives power from the nearby Summit Utility substation. In addition to the NJT Summit traction substation, three other switching facilities are located along the line. Commuter rail The term can refer to systems with a wide variety of different features and service frequencies, but

3402-417: Is often a case of asset sweating , by using a single large combined fleet for intercity and regional services. Loco hauled services are usually run in push-pull formation, that is, the train can run with the locomotive at the "front" or "rear" of the train (pushing or pulling). Trains are often equipped with a control cab at the other end of the train from the locomotive, allowing the train operator to operate

3528-901: Is often used in contrast to rapid transit or light rail . Some services share similarities with both commuter rail and high-frequency rapid transit ; examples include German S-Bahn in some cities, the Réseau Express Régional (RER) in Paris, the S Lines in Milan, many Japanese commuter systems, the East Rail line in Hong Kong, and some Australasian suburban networks, such as Sydney Trains . Many commuter rail systems share tracks with other passenger services and freight . In North America, commuter rail sometimes refers only to systems that primarily operate during rush hour and offer little to no service for

3654-1834: Is one suburban rail called the Chittagong Circular Railway . Another suburban railway called the Dhaka Circular Railway is currently proposed. Karachi in Pakistan has a circular railway since 1969. Tehran Metro currently operates the Line 5 commuter line between Tehran and Karaj . Turkey has lines connecting Başkentray , İZBAN , Marmaray and Gaziray . Major metropolitan areas in most European countries are usually served by extensive commuter/suburban rail systems. Well-known examples include BG Voz in Belgrade (Serbia), S-Bahn in Germany, Austria and German-speaking areas of Switzerland, Proastiakos in Greece, RER in France and Belgium, Servizio ferroviario suburbano in Italy, Cercanías and Rodalies ( Catalonia ) in Spain, CP Urban Services in Portugal, Esko in Prague and Ostrava (Czech Republic), HÉV in Budapest (Hungary) and DART in Dublin (Ireland). London has multiple commuter rail routes: The Merseyrail network in Liverpool consists of two commuter rail routes powered by third rail, both of which branch out at one end. At

3780-470: Is operationally more like a typical metro system (frequent trains, an emphasis on standing passengers , short station spacings) than it is like commuter rail in other countries. Japanese commuter rail commonly interline with city center subway lines, with commuter rail trains continuing into the subway network, and then out onto different commuter rail systems on the other side of the city. Many Japanese commuter systems operate various stopping patterns to reduce

3906-719: Is single-tracked with passing sidings at Murray Hill , Stirling , Bernardsville and west of Far Hills . At Summit , the Gladstone Branch joins with the Morristown Line . East of Newark Broad Street station , Gladstone Line trains may either continue to Hoboken Terminal, where PATH trains or NY Waterway ferries allow connection to New York, or use the Kearny Connection to diverge to New York Penn Station; two peak-hour trains from Gladstone offer direct trips to/from New York Penn Station. On weekdays during rush hours,

4032-526: Is still possible to tell them apart. Some operators, for example Thameslink , focus solely on commuter services. Others, such as Avanti West Coast and LNER , run solely intercity services. Others still, such as GWR and EMR , run a mixture of commuter, regional and intercity services. Some of these operators use different branding for different types of service (for example EMR brands its trains as either "InterCity", "Connect" for London commuter services, and "Regional") but even for those operators that do not,

4158-414: Is the same as placing an automobile's transmission into neutral while the engine is running. To set the locomotive in motion, the reverser control handle is placed into the correct position (forward or reverse), the brake is released and the throttle is moved to the run 1 position (the first power notch). An experienced engine driver can accomplish these steps in a coordinated fashion that will result in

4284-406: Is the site of the former Mine Brook station, a flag stop in the line's DL&W years. Mine Brook is the only station that was never rebuilt or even acquired by New Jersey Transit. Today, all that is left of the station is gravel where the platform used to be and a small gravel road where the parking used to be. The line then crosses Route 202 and enters Far Hills station, which has a station depot and

4410-570: Is used in Australia (Sydney for example) to describe the regional trains operating beyond the boundaries of the suburban services, even though some of these "inter-city" services stop all stations similar to German regional services. In this regard, the German service delineations and naming conventions are clearer and better used for academic purposes. Sometimes high-speed rail can serve daily use of commuters. The Japanese Shinkansen high speed rail system

4536-426: Is widely used in many commuter rail trains to increase capacity in rush hours. Carriages are usually not organized to increase seating capacity (although in some trains at least one carriage would feature more doors to facilitate easier boarding and alighting and bench seats so that they can be folded up during rush hour to provide more standing room) even in the case of commuting longer than 50 km and commuters in

4662-900: The Brisbane ( Queensland Rail 's City network ) and Perth ( Transperth ) systems in Australia, in some systems in Sweden, and on the Genoa-Casella line in Italy. Some countries and regions, including Finland , India, Pakistan, Russia , Brazil and Sri Lanka, as well as San Francisco ( BART ) in the US and Melbourne and Adelaide in Australia, use broad gauge track. Metro rail and rapid transit usually cover smaller inner-urban areas within 12 to 20 km (7 to 12 mi) of city centers, with shorter stop spacing, use rolling stocks with larger standing spaces, lower top speed and higher acceleration, designed for short-distance travel. They also run more frequently, to

4788-637: The Burlington Route and Union Pacific used custom-built diesel " streamliners " to haul passengers, starting in late 1934. Burlington's Zephyr trainsets evolved from articulated three-car sets with 600 hp power cars in 1934 and early 1935, to the Denver Zephyr semi-articulated ten car trainsets pulled by cab-booster power sets introduced in late 1936. Union Pacific started diesel streamliner service between Chicago and Portland Oregon in June 1935, and in

4914-717: The Busch-Sulzer company in 1911. Only limited success was achieved in the early twentieth century with internal combustion engined railcars, due, in part, to difficulties with mechanical drive systems. General Electric (GE) entered the railcar market in the early twentieth century, as Thomas Edison possessed a patent on the electric locomotive, his design actually being a type of electrically propelled railcar. GE built its first electric locomotive prototype in 1895. However, high electrification costs caused GE to turn its attention to internal combustion power to provide electricity for electric railcars. Problems related to co-ordinating

5040-600: The Canadian National Railways became the first North American railway to use diesels in mainline service with two units, 9000 and 9001, from Westinghouse. However, these early diesels proved expensive and unreliable, with their high cost of acquisition relative to steam unable to be realized in operating cost savings as they were frequently out of service. It would be another five years before diesel–electric propulsion would be successfully used in mainline service, and nearly ten years before fully replacing steam became

5166-747: The Chennai MRTS , also covers over 300 stations and carries more than 2.5 million people daily to different areas in Chennai and its surroundings. Other commuter railways in India include the Hyderabad MMTS , Delhi Suburban Railway , Pune Suburban Railway and Lucknow-Kanpur Suburban Railway . In 2020, Government of India approved Bengaluru Suburban Railway to connect Bengaluru and its suburbs. It will be unique and first of its kind in India as it will have metro like facilities and rolling stock. In Bangladesh, there

5292-490: The DFH1 , began in 1964 following the construction of a prototype in 1959. In Japan, starting in the 1920s, some petrol–electric railcars were produced. The first diesel–electric traction and the first air-streamed vehicles on Japanese rails were the two DMU3s of class Kiha 43000 (キハ43000系). Japan's first series of diesel locomotives was class DD50 (国鉄DD50形), twin locomotives, developed since 1950 and in service since 1953. In 1914,

5418-519: The Greater Tokyo Area , Seoul metropolitan area , and Jabodetabek area have to stand in the train for more than an hour. Currently there are not many examples of commuter rail in Africa . Metrorail operates in the major cities of South Africa , and there are some commuter rail services in Algeria , Botswana , Kenya , Morocco , Egypt and Tunisia . In Algeria, SNTF operates commuter rail lines between

5544-811: The Guangshen Railway have more frequent metro-like service. The two MTR lines which are owned and formerly operated by the Kowloon-Canton Railway Corporation ( East Rail line and Tuen Ma line which is integrated from the former West Rail line and Ma On Shan line in 2021), then the "KCR" ), and MTR's own Tung Chung line connect the new towns in New Territories and the city centre Kowloon together with frequent intervals, and some New Territories-bound trains terminate at intermediate stations, providing more frequent services in Kowloon and

5670-571: The Jakarta city center with surrounding cities and sub-urbans in Banten and West Java provinces, including Depok , Bogor , Tangerang , Serpong , Rangkasbitung , Bekasi and Cikarang . In July 2015, KRL Commuterline served more than 850,000 passengers per day, which is almost triple of the 2011 figures, but still less than 3.5% of all Jabodetabek commutes. Other commuter rail systems in Indonesia include

5796-947: The Metro Surabaya Commuter Line , Commuter Line Bandung , KAI Commuter Yogyakarta–Solo Line , Kedung Sepur , and the Sri Lelawangsa . In the Philippines, the Philippine National Railways has two commuter rail systems currently operational; the PNR Metro Commuter Line in the Greater Manila Area and the PNR Bicol Commuter in the Bicol Region . A new commuter rail line in Metro Manila,

5922-597: The North–South Commuter Railway , is currently under construction. Its North section is set to be partially opened by 2021. In Malaysia, there are two commuter services operated by Keretapi Tanah Melayu . They are the KTM Komuter that serves Kuala Lumpur and the surrounding Klang Valley area , and the KTM Komuter Northern Sector that serves Greater Penang , Perak , Kedah and Perlis in

6048-753: The Shanghai–Nanjing High-Speed Railway , serve a similar role with many more under construction or planned. In South Korea, some sections of the high-speed rail network are also heavily used by commuters, such as the section between Gwangmyeong Station and Seoul Station on the KTX network ( Gyeongbu HSR Line ), or the section between Dongtan Station and Suseo station on the SRT Line. The high-speed services linking Zürich , Bern and Basel in Switzerland (200 km/h (120 mph)) have brought

6174-484: The Società per le Strade Ferrate del Mediterrano in southern Italy in 1926, following trials in 1924–25. The six-cylinder two-stroke motor produced 440 horsepower (330 kW) at 500   rpm, driving four DC motors, one for each axle. These 44 tonnes (43 long tons; 49 short tons) locomotives with 45 km/h (28 mph) top speed proved quite successful. In 1924, two diesel–electric locomotives were taken in service by

6300-833: The Soviet railways , almost at the same time: In 1935, Krauss-Maffei , MAN and Voith built the first diesel–hydraulic locomotive, called V 140 , in Germany. Diesel–hydraulics became the mainstream in diesel locomotives in Germany since the German railways (DRG) were pleased with the performance of that engine. Serial production of diesel locomotives in Germany began after World War II. In many railway stations and industrial compounds, steam shunters had to be kept hot during many breaks between scattered short tasks. Therefore, diesel traction became economical for shunting before it became economical for hauling trains. The construction of diesel shunters began in 1920 in France, in 1925 in Denmark, in 1926 in

6426-573: The Underground and the Overground , Elizabeth line , Thameslink along with other commuter rail operators , Madrid's Metro and Cercanías , Barcelona's Metro and Rodalies , and Tokyo's subway and the JR lines along with various privately owned and operated commuter rail systems. Regional rail usually provides rail services between towns and cities, rather than purely linking major population hubs in

6552-426: The Yamanote Line , Keihin Tohoku Line , Chūō–Sōbu Line services arguably are more akin to rapid transit with frequent stops, simple stopping patterns (relative to other JR East lines) no branching services and largely serving the inner suburbs; other services along the Chūō Rapid Line , Sōbu Rapid Line / Yokosuka Line , Ueno–Tokyo Line , Shōnan–Shinjuku Line etc. are mid-distance services from suburban lines in

6678-436: The driving wheels . The most common are diesel–electric locomotives and diesel–hydraulic. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in

6804-406: The electrification of the line in 1944. Afterwards, the company kept them in service as boosters until 1965. Fiat claims to have built the first Italian diesel–electric locomotive in 1922, but little detail is available. Several Fiat- TIBB Bo'Bo' diesel–locomotives were built for service on the 950 mm ( 3 ft  1 + 3 ⁄ 8  in ) narrow gauge Ferrovie Calabro Lucane and

6930-432: The 1,500 kW (2,000 hp) British Rail 10100 locomotive), though only few have proven successful (such as the 1,342 kW (1,800 hp) DSB Class MF ). In a diesel–electric locomotive , the diesel engine drives either an electrical DC generator (generally, less than 3,000 hp (2,200 kW) net for traction), or an electrical AC alternator-rectifier (generally 3,000   hp net or more for traction),

7056-411: The 1960s, the DC generator was replaced by an alternator using a diode bridge to convert its output to DC. This advance greatly improved locomotive reliability and decreased generator maintenance costs by elimination of the commutator and brushes in the generator. Elimination of the brushes and commutator, in turn, eliminated the possibility of a particularly destructive type of event referred to as

7182-449: The 1990s, starting with the Electro-Motive SD70MAC in 1993 and followed by General Electric's AC4400CW in 1994 and AC6000CW in 1995. The Trans-Australian Railway built 1912 to 1917 by Commonwealth Railways (CR) passes through 2,000 km of waterless (or salt watered) desert terrain unsuitable for steam locomotives. The original engineer Henry Deane envisaged diesel operation to overcome such problems. Some have suggested that

7308-402: The 300 km/h (186 mph) Nuremberg–Ingolstadt high-speed railway . The regional trains Stockholm – Uppsala , Stockholm– Västerås , Stockholm– Eskilstuna and Gothenburg – Trollhättan in Sweden reach 200 km/h (120 mph) and have many daily commuters. In Great Britain , the HS1 domestic services between London and Ashford runs at a top speed of 225 km/h, and in peak hours

7434-420: The CR worked with the South Australian Railways to trial diesel traction. However, the technology was not developed enough to be reliable. As in Europe, the usage of internal combustion engines advanced more readily in self-propelled railcars than in locomotives: A diesel–mechanical locomotive uses a mechanical transmission in a fashion similar to that employed in most road vehicles. This type of transmission

7560-448: The Central Business Districts (CBDs) of these three cities within 1 hour of each other. This has resulted in unexpectedly high demand for new commuter trips between the three cities and a corresponding increase in suburban rail passengers accessing the high-speed services at the main city-centre stations ( Hauptbahnhof ). The Regional-Express commuter service between Munich and Nuremberg in Germany runs at 200 km/h (120 mph) on

7686-402: The East Rail Line share tracks with intercity trains to mainland China . The three KCR lines are integrated into the MTR network since 2008 and most passengers do not need to exit and re-enter the system through separate fare gates and purchase separate tickets to transfer between such lines and the rest of the network (the exceptions are between the Tuen Ma line's East Tsim Sha Tsui station and

7812-429: The Morris & Essex from Hoboken or New York to Summit . At Summit, schedules are timed for most Morristown trains and Gladstone trains, permitting easy transfers across the platform or one right after the other. Just west of Summit, the Morristown Line separates. The Gladstone Branch curves left at the Summit substation before entering New Providence . After New Providence, the line passes its first grade crossing at

7938-443: The Morris and Essex. The Passaic and Delaware Extension Railroad was chartered in 1890 and opened later that year, extending the line to its current terminus in Gladstone, New Jersey . The DL&W continued to operate this line throughout its lifespan as the Passaic and Delaware Branch, later becoming labelled the Gladstone Branch. In 1960, the DL&W merged with the Erie Railroad to form the Erie Lackawanna Railway , who took over

8064-433: The Netherlands carry many commuters, while their equipment, range, and speeds are similar to those of commuter trains in some larger countries. The United Kingdom has a privatised rail system, with different routes and services covered by different private operators. The distinction between commuter and intercity rail is not as clear as it was before privatisation (when InterCity existed as a brand of its own), but usually it

8190-718: The Netherlands, and in 1927 in Germany. After a few years of testing, hundreds of units were produced within a decade. Diesel-powered or "oil-engined" railcars, generally diesel–mechanical, were developed by various European manufacturers in the 1930s, e.g. by William Beardmore and Company for the Canadian National Railways (the Beardmore Tornado engine was subsequently used in the R101 airship). Some of those series for regional traffic were begun with gasoline motors and then continued with diesel motors, such as Hungarian BC (The class code doesn't tell anything but "railmotor with 2nd and 3rd class seats".), 128 cars built 1926–1937, or German Wismar railbuses (57 cars 1932–1941). In France,

8316-403: The Passaic River a third time before entering Somerset County and Bernards Township and crossing Pond Hill Road. After this crossing, the Millington quarry can be seen on the left (going westbound). Here, there is a short passing siding; although trains going opposite directions can also pass each other here, this area is not usually used for that. Lyons station is the next stop. The line enters

8442-411: The Tsuen Wan line's Tsim Sha Tsui station . In Taiwan, the Western line in the Taipei - Taoyuan Metropolitan Area, Taichung Metropolitan Area and Tainan - Kaohsiung Metropolitan Area as well as the Neiwan - Liujia line in the Hsinchu Area are considered commuter rail. In South Korea, the Seoul Metropolitan Subway includes a total of 22 lines, and some of its lines are suburban lines. This

8568-573: The United States, diesel–electric propulsion was brought to high-speed mainline passenger service in late 1934, largely through the research and development efforts of General Motors dating back to the late 1920s and advances in lightweight car body design by the Budd Company . The economic recovery from World War II hastened the widespread adoption of diesel locomotives in many countries. They offered greater flexibility and performance than steam locomotives , as well as substantially lower operating and maintenance costs. The earliest recorded example of

8694-427: The War Production Board put a halt to building new passenger equipment and gave naval uses priority for diesel engine production. During the petroleum crisis of 1942–43 , coal-fired steam had the advantage of not using fuel that was in critically short supply. EMD was later allowed to increase the production of its FT locomotives and ALCO-GE was allowed to produce a limited number of DL-109 road locomotives, but most in

8820-407: The area. The only part of the New Jersey West Line Railroad that was completed was from Summit west to Bernardsville. The New Jersey West Line Railroad was dissolved in 1878 and the assets were sold off. The Summit to Bernardsville line was then purchased by the Passaic and Delaware Railroad. The Delaware Lackawanna and Western Railroad (DL&W) leased the line on November 1, 1882 as a branch of

8946-433: The axles connected to traction motors, with the other two as idler axles for weight distribution. In the late 1980s, the development of high-power variable-voltage/variable-frequency (VVVF) drives, or "traction inverters", allowed the use of polyphase AC traction motors, thereby also eliminating the motor commutator and brushes. The result is a more efficient and reliable drive that requires relatively little maintenance and

9072-706: The benefits of an electric locomotive without the railroad having to bear the sizeable expense of electrification. The unit successfully demonstrated, in switching and local freight and passenger service, on ten railroads and three industrial lines. Westinghouse Electric and Baldwin collaborated to build switching locomotives starting in 1929. However, the Great Depression curtailed demand for Westinghouse's electrical equipment, and they stopped building locomotives internally, opting to supply electrical parts instead. In June 1925, Baldwin Locomotive Works outshopped

9198-443: The branch line. In 1983, New Jersey Transit assumed control of the line, and continues to operate it to this day. The branch received severe damage from Hurricane Sandy on October 29–30, 2012, especially to the catenary and signal system, causing a suspension of service for one month. High winds brought down five tall catenary poles (whose replacements had to be custom-made), approximately five miles of catenary, and 49 trees across

9324-420: The break in transmission during gear changing, such as the S.S.S. (synchro-self-shifting) gearbox used by Hudswell Clarke . Diesel–mechanical propulsion is limited by the difficulty of building a reasonably sized transmission capable of coping with the power and torque required to move a heavy train. A number of attempts to use diesel–mechanical propulsion in high power applications have been made (for example,

9450-512: The capital Algiers and its southern and eastern suburbs. They also serve to connect Algiers ' main universities to each other. The Dar es Salaam commuter rail offers intracity services in Dar es Salaam , Tanzania. In Botswana, the ( Botswana Railways ) "BR Express" has a commuter train between Lobatse and Gaborone . In Japan, commuter rail systems have extensive network and frequent service and are heavily used. In many cases, Japanese commuter rail

9576-639: The dense parts of Seoul, some track sections extend far outside of the city, and operate large sections at ground level, such as on the Line 1 , Line 3 and Line 4 . In Busan, the Donghae Line , while part of the Busan Metro system, mostly functions as a commuter rail line. In Indonesia , the KRL Commuterline is the largest commuter rail system in the country, serving the Greater Jakarta . It connects

9702-626: The eastbound train arrives on the track closest to the station platform. Schedules are timed for a convenient meetup at Murray Hill. After Murray Hill, the line passes three more grade crossings: at Warner Field Path, at Union Avenue, and at Snyder Avenue. There used to be a siding for the General Chemical Company plant just west of the Snyder Avenue crossing, but this was removed between 2018 and 2019. The line crosses Plainfield Avenue and enters Berkeley Heights station , which also contains

9828-443: The engine governor and electrical or electronic components, including switchgear , rectifiers and other components, which control or modify the electrical supply to the traction motors. In the most elementary case, the generator may be directly connected to the motors with only very simple switchgear. Originally, the traction motors and generator were DC machines. Following the development of high-capacity silicon rectifiers in

9954-419: The engine and traction motor with a single lever; subsequent improvements were also patented by Lemp. Lemp's design solved the problem of overloading and damaging the traction motors with excessive electrical power at low speeds, and was the prototype for all internal combustion–electric drive control systems. In 1917–1918, GE produced three experimental diesel–electric locomotives using Lemp's control design,

10080-423: The engine driver operates the controls. When the throttle is in the idle position, the prime mover receives minimal fuel, causing it to idle at low RPM. In addition, the traction motors are not connected to the main generator and the generator's field windings are not excited (energized) – the generator does not produce electricity without excitation. Therefore, the locomotive will be in "neutral". Conceptually, this

10206-496: The engine uses the siding to run around the train to reverse direction. In 2019, the Dover and Delaware River Railroad took over freight service along the line. Like the Morristown Line , the Gladstone Branch is electrified using overhead catenary at 25 kV 60 Hz. Traction power comes from the NJT substation at Summit , which also powers much of the Morristown Line. The Summit substation

10332-456: The first diesel railcar was Renault VH , 115 units produced 1933/34. In Italy, after six Gasoline cars since 1931, Fiat and Breda built a lot of diesel railmotors, more than 110 from 1933 to 1938 and 390 from 1940 to 1953, Class 772 known as Littorina , and Class ALn 900. In the 1930s, streamlined highspeed diesel railcars were developed in several countries: In 1945, a batch of 30 Baldwin diesel–electric locomotives, Baldwin 0-6-6-0 1000 ,

10458-480: The first known to be built in the United States. Following this development, the 1923 Kaufman Act banned steam locomotives from New York City, because of severe pollution problems. The response to this law was to electrify high-traffic rail lines. However, electrification was uneconomical to apply to lower-traffic areas. The first regular use of diesel–electric locomotives was in switching (shunter) applications, which were more forgiving than mainline applications of

10584-553: The following year would add Los Angeles, CA , Oakland, CA , and Denver, CO to the destinations of diesel streamliners out of Chicago. The Burlington and Union Pacific streamliners were built by the Budd Company and the Pullman-Standard Company , respectively, using the new Winton engines and power train systems designed by GM's Electro-Motive Corporation . EMC's experimental 1800 hp B-B locomotives of 1935 demonstrated

10710-466: The former BR 's Regional Railways , France's TER ( Transport express régional ), Germany's Regionalexpress and Regionalbahn , and South Korea's Tonggeun and Mugunghwa-ho services. In some European countries, the distinction between commuter trains and long-distance/intercity trains is subtle, due to the relatively short distances involved. For example, so-called " intercity " trains in Belgium and

10836-406: The freight market including their own F series locomotives. GE subsequently dissolved its partnership with ALCO and would emerge as EMD's main competitor in the early 1960s, eventually taking the top position in the locomotive market from EMD. Early diesel–electric locomotives in the United States used direct current (DC) traction motors but alternating current (AC) motors came into widespread use in

10962-612: The last customer, the Reheis Chemical Company, was bought out by the General Chemical Company and planned to close down in 2008. The apparent last freight train made its run on November 7, 2008; however, seven months later the facility began receiving shipments again, on June 19, 2009. Although this industry is east of the Berkeley Heights station , the freight trains actually operate as far west as Stirling, where

11088-555: The limitations of contemporary diesel technology and where the idling economy of diesel relative to steam would be most beneficial. GE entered a collaboration with the American Locomotive Company (ALCO) and Ingersoll-Rand (the "AGEIR" consortium) in 1924 to produce a prototype 300 hp (220 kW) "boxcab" locomotive delivered in July 1925. This locomotive demonstrated that the diesel–electric power unit could provide many of

11214-549: The line operates in two zones: all stops from Hoboken to Summit; or express from Hoboken to Short Hills (one station east of Summit), and then local to Gladstone. All weekend and off-peak service is local across the entire line. The Gladstone Branch proper, the part of the Gladstone Line west of the junction with the Morris & Essex at Summit, is The line primarily operates in the eastbound direction weekday peak hours, except for

11340-426: The line. Afterwards, the line crosses over Interstate 287 before curving left and entering Bernardsville station after crossing under Mount Airy Road. At Bernardsville, the track splits in two, again to allow trains to pass each other if necessary, and the line crosses Depot Place. Continuing westward, the line parallels U.S. Route 202 and crosses Old Quarry Road, Meeker Road, and Whitenack Road. At Whitenack Road

11466-431: The locomotive business were restricted to making switch engines and steam locomotives. In the early postwar era, EMD dominated the market for mainline locomotives with their E and F series locomotives. ALCO-GE in the late 1940s produced switchers and road-switchers that were successful in the short-haul market. However, EMD launched their GP series road-switcher locomotives in 1949, which displaced all other locomotives in

11592-524: The mid-1950s. Generally, diesel traction in Italy was of less importance than in other countries, as it was amongst the most advanced countries in the electrification of the main lines and as Italian geography makes freight transport by sea cheaper than rail transportation even on many domestic connections. Adolphus Busch purchased the American manufacturing rights for the diesel engine in 1898 but never applied this new form of power to transportation. He founded

11718-543: The multiple-unit control systems used for the cab/booster sets and the twin-engine format used with the later Zephyr power units. Both of those features would be used in EMC's later production model locomotives. The lightweight diesel streamliners of the mid-1930s demonstrated the advantages of diesel for passenger service with breakthrough schedule times, but diesel locomotive power would not fully come of age until regular series production of mainline diesel locomotives commenced and it

11844-917: The northern region of Peninsular Malaysia. In Thailand, the Greater Bangkok Commuter rail and the Airport Rail Link serve the Bangkok Metropolitan Region . The SRT Red Lines , a new commuter line in Bangkok, started construction in 2009. It opened in 2021. Another commuter rail system in Southeast Asia is the Yangon Circular Railway in Myanmar . In India, commuter rail systems are present in major cities and form an important part of people's daily lives. Mumbai Suburban Railway ,

11970-1003: The number expected to rise even higher upon full completion of the Acharnes Railway Center . Eskişehir-Ankara and Konya-Ankara high speed train routes serve as high speed commuter trains in Turkey. Commuter/suburban trains are usually optimized for maximum passenger volume, in most cases without sacrificing too much comfort and luggage space, though they seldom have all the amenities of long-distance trains. Cars may be single- or double-level , and aim to provide seating for all. Compared to intercity trains, they have less space, fewer amenities and limited baggage areas. Commuter rail trains are usually composed of multiple units , which are self-propelled, bidirectional, articulated passenger rail cars with driving motors on each (or every other) bogie . Depending on local circumstances and tradition they may be powered either by diesel engines located below

12096-522: The oldest suburban rail system in Asia, carries more than 7.24 million commuters on a daily basis which constitutes more than half of the total daily passenger capacity of the Indian Railways itself. Kolkata Suburban Railway , one of the largest suburban railway networks in the world, consists of more than 450 stations and carries more than 3.5 million commuters per day. The Chennai Suburban Railway along with

12222-506: The other, the Northern line continues out of the city centre to a mainline rail interchange, while the Wirral line has a city-centre loop. Diesel locomotive A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine . Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to

12348-688: The outer reaches of Greater Tokyo through operating into these lines to form a high frequency corridor though central Tokyo. Other commuter rail routes in Japan include: Commuter rail systems have been inaugurated in several cities in China such as Beijing , Shanghai , Zhengzhou , Wuhan , Changsha and the Pearl River Delta . With plans for large systems in northeastern Zhejiang , Jingjinji , and Yangtze River Delta areas. The level of service varies considerably from line to line ranging high to near high speeds. More developed and established lines such as

12474-402: The output of which provides power to the traction motors that drive the locomotive. There is no mechanical connection between the diesel engine and the wheels. The important components of diesel–electric propulsion are the diesel engine (also known as the prime mover ), the main generator/alternator-rectifier, traction motors (usually with four or six axles), and a control system consisting of

12600-423: The passenger compartment ( diesel multiple units ) or by electricity picked up from third rails or overhead lines ( electric multiple units ). Multiple units are almost invariably equipped with control cabs at both ends, which is why such units are so frequently used to provide commuter services, due to the associated short turn-around time. Locomotive hauled services are used in some countries or locations. This

12726-580: The performance and reliability of the new 567 model engine in passenger locomotives, EMC was eager to demonstrate diesel's viability in freight service. Following the successful 1939 tour of EMC's FT demonstrator freight locomotive set, the stage was set for dieselization of American railroads. In 1941, ALCO-GE introduced the RS-1 road-switcher that occupied its own market niche while EMD's F series locomotives were sought for mainline freight service. The US entry into World War II slowed conversion to diesel;

12852-478: The prime mover and electric motor were immediately encountered, primarily due to limitations of the Ward Leonard current control system that had been chosen. GE Rail was formed in 1907 and 112 years later, in 2019, was purchased by and merged with Wabtec . A significant breakthrough occurred in 1914, when Hermann Lemp , a GE electrical engineer, developed and patented a reliable control system that controlled

12978-450: The required performance for a fast, lightweight passenger train. The second milestone, and the one that got American railroads moving towards diesel, was the 1938 delivery of GM's Model 567 engine that was designed specifically for locomotive use, bringing a fivefold increase in life of some mechanical parts and showing its potential for meeting the rigors of freight service. Diesel–electric railroad locomotion entered mainline service when

13104-552: The rest of the day, with regional rail being used to refer to systems that offer all-day service. Most commuter (or suburban) trains are built to main line rail standards, differing from light rail or rapid transit (metro rail) systems by: Compared to rapid transit (or metro rail), commuter/suburban rail often has lower frequency , following a schedule rather than fixed intervals, and fewer stations spaced further apart. They primarily serve lower density suburban areas (non inner-city), generally only having one or two stops in

13230-488: The same right-of-way can drastically reduce system construction costs. However, frequently they are built with dedicated tracks within that right-of-way to prevent delays, especially where service densities have converged in the inner parts of the network. Most such trains run on the local standard gauge track. Some systems may run on a narrower or broader gauge. Examples of narrow gauge systems are found in Japan, Indonesia , Malaysia , Thailand , Taiwan, Switzerland, in

13356-524: The station after crossing a bridge over South Finley Avenue. After another crossing at Lake Road near Ridge High School and another bridge over West Oak Street, the line enters Basking Ridge station at the crossing at Ridge Street. Until recently, the original semaphore signal from the DL&;W years used to sit atop the Basking Ridge station over the platform, one of the last vestiges of the previous operator of

13482-480: The station. Continuing westward, the line crosses Northfield Road by Millington Elementary School before curving right, crossing Division Avenue, and entering Millington station . At Millington, there used to be another gateless crossing on the other side of the platform, where the line will cross River Road, a small connection road between Commerce Street and Long Hill Road, but this crossing was closed off sometime around 2014-2015. The line continues westward, crossing

13608-405: The success of the custom streamliners, sought to expand the market for diesel power by producing standardized locomotives under their Electro-Motive Corporation . In 1936, EMC's new factory started production of switch engines. In 1937, the factory started producing their new E series streamlined passenger locomotives, which would be upgraded with more reliable purpose-built engines in 1938. Seeing

13734-432: The throttle from notch 2 to notch 4 without stopping at notch 3. This feature was intended to prevent rough train handling due to abrupt power increases caused by rapid throttle motion ("throttle stripping", an operating rules violation on many railroads). Modern locomotives no longer have this restriction, as their control systems are able to smoothly modulate power and avoid sudden changes in train loading regardless of how

13860-479: The throttle setting, as determined by the engine driver and the speed at which the prime mover is running (see Control theory ). Locomotive power output, and therefore speed, is typically controlled by the engine driver using a stepped or "notched" throttle that produces binary -like electrical signals corresponding to throttle position. This basic design lends itself well to multiple unit (MU) operation by producing discrete conditions that assure that all units in

13986-461: The towns closer to Kowloon. They use rolling stocks with a faster maximum speed and have longer stop spacing compared to other lines which only run in the inner urban area, but in order to maximise capacity and throughput, these rolling stocks have longitudinal seatings, 5 pairs of doors in each carriage with large standing spaces like the urban lines, and run as frequent as well. Most of the sections of these four lines are overground and some sections of

14112-431: The tracks. Gladstone service resumed on Monday, December 3 with electric Midtown Direct trains to Penn Station and diesel-powered trains to Hoboken; full electric operation was impractical until substation damage near Hoboken was repaired in early 2013. Gladstone Line trains begin at Hoboken Terminal , with the exception of two weekday trains which run in and out of New York Penn Station . Gladstone Line trains run over

14238-515: The train from either end. The motive power for locomotive-hauled commuter trains may be either electric or diesel–electric , although some countries, such as Germany and some of the former Soviet-bloc countries, also use diesel–hydraulic locomotives. In the US and some other countries, a three-and-two seat plan is used. Middle seats on these trains are often less popular because passengers feel crowded and uncomfortable. In Japan, South Korea and Indonesia, longitudinal (sideways window-lining) seating

14364-549: The trains can be full with commuters standing. The Athens Suburban Railway in Greece consists of five lines, 4 of which are electrified. The Kiato – Piraeus line and the Aigio – Airport lines reach speeds of up to 180 km/h (112 mph). The Athens – Chalcis line is also expected to attain speeds of up to 200 km/h (124 mph) upon upgrading of the SKA–Oinoi railway sector. These lines also have many daily commuters, with

14490-478: The trains meet at Far Hills and Murray Hill. While Bernardsville and Stirling each have two tracks at the station, the second track at those two stations is less commonly used unless a train is running late. At the time of NJT acquisition, freight service was operated by Conrail . Upon the breakup of that company, the Norfolk Southern Railway inherited the business. Customers on the line dwindled, and

14616-517: The trains run between two or several cities (e.g. S-Bahn in the Ruhr area of Germany). Distances between stations may vary, but are usually much longer than those of urban rail systems. In city centres the train either has a terminal station or passes through the city centre with notably fewer station stops than those of urban rail systems. Toilets are often available on-board trains and in stations. Their ability to coexist with freight or intercity services in

14742-465: The travel time to distant locations, often using station passing loops instead of dedicated express tracks. It is notable that the larger Japanese commuter rail systems are owned and operated by for-profit private railway companies, without public subsidy. East Japan Railway Company operates a large suburban train network in Tokyo with various lines connecting the suburban areas to the city center. While

14868-574: The type of train, amenities offered, and stopping pattern, usually tell the services apart. Russian commuter trains , on the other hand, frequently cover areas larger than Belgium itself, although these are still short distances by Russian standards. They have a different ticketing system from long-distance trains, and in major cities they often operate from a separate section of the train station. Some consider "inter-city" service to be that which operates as an express service between two main city stations, bypassing intermediate stations. However, this term

14994-451: The use of an internal combustion engine in a railway locomotive is the prototype designed by William Dent Priestman , which was examined by William Thomson, 1st Baron Kelvin in 1888 who described it as a " Priestman oil engine mounted upon a truck which is worked on a temporary line of rails to show the adaptation of a petroleum engine for locomotive purposes." In 1894, a 20 hp (15 kW) two-axle machine built by Priestman Brothers

15120-470: The way inter-city rail does. Regional rail operates outside major cities. Unlike Inter-city, it stops at most or all stations between cities. It provides a service between smaller communities along the line that are often byproducts of ribbon developments , and also connects with long-distance services at interchange stations located at junctions, terminals, or larger towns along the line. Alternative names are "local train" or "stopping train". Examples include

15246-657: The world's first functional diesel–electric railcars were produced for the Königlich-Sächsische Staatseisenbahnen ( Royal Saxon State Railways ) by Waggonfabrik Rastatt with electric equipment from Brown, Boveri & Cie and diesel engines from Swiss Sulzer AG . They were classified as DET 1 and DET 2 ( de.wiki ). Because of a shortage of petrol products during World War I, they remained unused for regular service in Germany. In 1922, they were sold to Swiss Compagnie du Chemin de fer Régional du Val-de-Travers , where they were used in regular service up to

15372-467: Was 95 tonnes and the power was 883 kW (1,184 hp) with a maximum speed of 100 km/h (62 mph). Small numbers of prototype diesel locomotives were produced in a number of countries through the mid-1920s. One of the first domestically developed Diesel vehicles of China was the Dongfeng DMU (东风), produced in 1958 by CSR Sifang . Series production of China's first Diesel locomotive class,

15498-678: Was delivered from the United States to the railways of the Soviet Union. In 1947, the London, Midland and Scottish Railway (LMS) introduced the first of a pair of 1,600 hp (1,200 kW) Co-Co diesel–electric locomotives (later British Rail Class D16/1 ) for regular use in the United Kingdom, although British manufacturers such as Armstrong Whitworth had been exporting diesel locomotives since 1930. Fleet deliveries to British Railways, of other designs such as Class 20 and Class 31, began in 1957. Series production of diesel locomotives in Italy began in

15624-400: Was one of the principal design considerations that had to be solved in early diesel–electric locomotive development and, ultimately, led to the complex control systems in place on modern units. The prime mover's power output is primarily determined by its rotational speed ( RPM ) and fuel rate, which are regulated by a governor or similar mechanism. The governor is designed to react to both

15750-490: Was shown suitable for full-size passenger and freight service. Following their 1925 prototype, the AGEIR consortium produced 25 more units of 300 hp (220 kW) "60 ton" AGEIR boxcab switching locomotives between 1925 and 1928 for several New York City railroads, making them the first series-produced diesel locomotives. The consortium also produced seven twin-engine "100 ton" boxcabs and one hybrid trolley/battery unit with

15876-719: Was used on the Hull Docks . In 1896, an oil-engined railway locomotive was built for the Royal Arsenal in Woolwich , England, using an engine designed by Herbert Akroyd Stuart . It was not a diesel, because it used a hot-bulb engine (also known as a semi-diesel), but it was the precursor of the diesel. Rudolf Diesel considered using his engine for powering locomotives in his 1893 book Theorie und Konstruktion eines rationellen Wärmemotors zum Ersatz der Dampfmaschine und der heute bekannten Verbrennungsmotoren ( Theory and Construction of
