98-536: Sampark Kranti Express trains are a series of Superfast express trains operated by the Indian Railways providing quick connectivity to the national capital, New Delhi . The words Sampark and Kranti are borrowed from Sanskrit . Sampark( Devanagari :- सम्पर्क ) means Contact and Kranti( Devanagari :-क्रान्ति ) means Revolution. The combined name denotes the steps taken by Indian Railways to provide high speed train connections from cities around India with

196-459: A WCP-1 locomotives with seven coaches along the route. The Grand Trunk express commenced operating as a dedicated daily train between Madras and Delhi from 1 September 1930. WDM-1 , the first diesel locomotive introduced in 1957 was capable of speeds of up to 104 km/h (65 mph). In 1957, Indian Railways adopted 25 kV 50 Hz AC traction with the first runs beginning in December 1959 with

294-452: A combustion-powered locomotive (i.e., steam- or diesel-powered ) could cause a safety issue due to the risks of fire, explosion or fumes in a confined space. Battery locomotives are preferred for mine railways where gas could be ignited by trolley-powered units arcing at the collection shoes, or where electrical resistance could develop in the supply or return circuits, especially at rail joints, and allow dangerous current leakage into

392-713: A distance of 54 km (34 mi) in 57 minutes, averaging a speed of 57 km/h (35 mph). Earlier trains ran using steam locomotives , where barely reached speeds of 90 km/h (56 mph). With the introduction of WP class locomotives in 1947, speeds of 100 km/h (62 mph) were operated commercially. While the first electric train ran in Bombay in 1925 on DC traction, WCP-1 class electric locomotives were introduced in 1928, capable of hauling trains at speeds of up to 137 km/h (85 mph), though trains operated at lower speed. On 1 April 1929, Grand Trunk Express commenced operations between Peshawar in

490-429: A ground and polished journal that is integral to the axle. The other side of the housing has a tongue-shaped protuberance that engages a matching slot in the truck (bogie) bolster, its purpose being to act as a torque reaction device, as well as support. Power transfer from the motor to the axle is effected by spur gearing , in which a pinion on the motor shaft engages a bull gear on the axle. Both gears are enclosed in

588-415: A liquid-tight housing containing lubricating oil. The type of service in which the locomotive is used dictates the gear ratio employed. Numerically high ratios are commonly found on freight units, whereas numerically low ratios are typical of passenger engines. The Whyte notation system for classifying steam locomotives is not adequate for describing the variety of electric locomotive arrangements, though

686-480: A maximum operational speed of 160 km/h (99 mph). The actual operating speed was much lower due to track restrictions and congestion with top speeds restricted to 130 km/h (81 mph) for most trains. In December 2023, two modified WAP-5 locomotives were used to haul the Amrit Bharat train-set in a push-pull configuration, capable of reaching speeds of up to 160 km/h (99 mph). According to

784-593: A maximum permitted speed of 160 km/h (99 mph). The history of the Indian Railway began in 1832 with the proposal to construct the first railway line in India at Madras . In 1837, the first train ran on Red Hill railway line between Red Hills and Chintadripet in Madras and was hauled by a rotary steam engine imported from England . In 1853, the first passenger train ran between Bombay and Thane which covered

882-502: A maximum speed of 130 km/h (81 mph). WAP-5 class locomotives, initially imported from ABB in 1995 and later manufactured at Chittaranjan Locomotive Works in India, reached 184 km/h (114 mph) in trials and later set an Indian speed record by hauling an express train between Delhi and Agra at a speed of 160 km/h (99 mph) in 2014. In December 2009, the Ministry of Railways of Government of India envisaged

980-409: A modern locomotive can be up to 50% of the cost of the vehicle. Electric traction allows the use of regenerative braking, in which the motors are used as brakes and become generators that transform the motion of the train into electrical power that is then fed back into the lines. This system is particularly advantageous in mountainous operations, as descending locomotives can produce a large portion of

1078-490: A new type 3-phase asynchronous electric drive motors and generators for electric locomotives at the Fives-Lille Company. Kandó's early 1894 designs were first applied in a short three-phase AC tramway in Évian-les-Bains (France), which was constructed between 1896 and 1898. In 1918, Kandó invented and developed the rotary phase converter , enabling electric locomotives to use three-phase motors whilst supplied via

1176-407: A plan to increase the speed of passenger trains to 160–200 km/h (99–124 mph) on dedicated conventional tracks and improve the existing conventional lines to handle speeds of up to 160 km/h (99 mph). Dedicated Freight Corridor Corporation of India has built dedicated freight corridors across India to divert cargo traffic from the passenger railway tracks, thus helping increase

1274-473: A single overhead wire, carrying the simple industrial frequency (50 Hz) single phase AC of the high voltage national networks. Italian railways were the first in the world to introduce electric traction for the entire length of a mainline rather than just a short stretch. The 106 km Valtellina line was opened on 4 September 1902, designed by Kandó and a team from the Ganz Works . The electrical system

1372-410: A smaller rail parallel to the main track, above ground level. There are multiple pickups on both sides of the locomotive in order to accommodate the breaks in the third rail required by trackwork. This system is preferred in subways because of the close clearances it affords. During the initial development of railroad electrical propulsion, a number of drive systems were devised to couple the output of

1470-819: A speed of 13 km/h. During four months, the train carried 90,000 passengers on a 300-meter-long (984 feet) circular track. The electricity (150 V DC) was supplied through a third insulated rail between the tracks. A contact roller was used to collect the electricity. The world's first electric tram line opened in Lichterfelde near Berlin, Germany, in 1881. It was built by Werner von Siemens (see Gross-Lichterfelde Tramway and Berlin Straßenbahn ). Volk's Electric Railway opened in 1883 in Brighton. Also in 1883, Mödling and Hinterbrühl Tram opened near Vienna in Austria. It

1568-571: A ticket holder to board the train and share a berth. Reserved tickets can be booked by passengers who want to travel at short notice at higher fares through the Tatkal train ticket , where no refund is applicable on cancellation. A valid proof for the purchase of ticket along with photo identification is required to board the train. Unreserved tickets for short distance or unplanned travels may be purchased at stations or through UTS mobile app at any time before departure. Holders of such tickets may only board

1666-650: Is common in Canada and the U.S.) but not for passenger or mixed passenger/freight traffic like on many European railway lines, especially where heavy freight trains must be run at comparatively high speeds (80 km/h or more). These factors led to high degrees of electrification in most European countries. In some countries, like Switzerland, even electric shunters are common and many private sidings are served by electric locomotives. During World War II , when materials to build new electric locomotives were not available, Swiss Federal Railways installed electric heating elements in

1764-418: Is no easy way to do the voltage/current transformation for DC so efficiently as achieved by AC transformers. AC traction still occasionally uses dual overhead wires instead of single-phase lines. The resulting three-phase current drives induction motors , which do not have sensitive commutators and permit easy realisation of a regenerative brake . Speed is controlled by changing the number of pole pairs in

1862-1091: Is no engine and exhaust noise and less mechanical noise. The lack of reciprocating parts means electric locomotives are easier on the track, reducing track maintenance. Power plant capacity is far greater than any individual locomotive uses, so electric locomotives can have a higher power output than diesel locomotives and they can produce even higher short-term surge power for fast acceleration. Electric locomotives are ideal for commuter rail service with frequent stops. Electric locomotives are used on freight routes with consistently high traffic volumes, or in areas with advanced rail networks. Power plants, even if they burn fossil fuels , are far cleaner than mobile sources such as locomotive engines. The power can also come from low-carbon or renewable sources , including geothermal power , hydroelectric power , biomass , solar power , nuclear power and wind turbines . Electric locomotives usually cost 20% less than diesel locomotives, their maintenance costs are 25–35% lower, and cost up to 50% less to run. The chief disadvantage of electrification

1960-463: Is now employed largely unmodified by ÖBB to haul their Railjet which is however limited to a top speed of 230 km/h due to economic and infrastructure concerns. An electric locomotive can be supplied with power from The distinguishing design features of electric locomotives are: The most fundamental difference lies in the choice of AC or DC. The earliest systems used DC, as AC was not well understood and insulation material for high voltage lines

2058-414: Is powered by onboard batteries; a kind of battery electric vehicle . Such locomotives are used where a diesel or conventional electric locomotive would be unsuitable. An example is maintenance trains on electrified lines when the electricity supply is turned off. Another use for battery locomotives is in industrial facilities (e.g. explosives factories, oil, and gas refineries or chemical factories) where

2156-483: Is the high cost for infrastructure: overhead lines or third rail, substations, and control systems. The impact of this varies depending on local laws and regulations. For example, public policy in the U.S. interferes with electrification: higher property taxes are imposed on privately owned rail facilities if they are electrified. The EPA regulates exhaust emissions on locomotive and marine engines, similar to regulations on car & freight truck emissions, in order to limit

2254-452: Is widespread in Europe, with electric multiple units commonly used for passenger trains. Due to higher density schedules, operating costs are more dominant with respect to the infrastructure costs than in the U.S. and electric locomotives have much lower operating costs than diesel. In addition, governments were motivated to electrify their railway networks due to coal shortages experienced during

2352-505: The Ganz works and Societa Italiana Westinghouse , was an electro-mechanical converter , allowing the use of three-phase motors from single-phase AC, eliminating the need for two overhead wires. In 1923, the first phase-converter locomotive in Hungary was constructed on the basis of Kandó's designs and serial production began soon after. The first installation, at 16 kV 50 Hz, was in 1932 on

2450-570: The North Western Railway and Mangalore with two coaches detached and connected to Madras further. The Frontier Mail made its inaugural run between Bombay and Peshawar in 1928. Technical advancements led to automatic colour light signals become operational between Bombay and Byculla in 1928. In the subsequent years, the route from Bombay to Poona was electrified and in June 1930, the first deluxe train, Deccan Queen began running, hauled by

2548-603: The Pennsylvania Railroad applied classes to its electric locomotives as if they were steam. For example, the PRR GG1 class indicates that it is arranged like two 4-6-0 class G locomotives coupled back-to-back. UIC classification system was typically used for electric locomotives, as it could handle the complex arrangements of powered and unpowered axles and could distinguish between coupled and uncoupled drive systems. A battery–electric locomotive (or battery locomotive)

2646-635: The Pennsylvania Railroad , which had introduced electric locomotives because of the NYC regulation, electrified its entire territory east of Harrisburg, Pennsylvania . The Chicago, Milwaukee, St. Paul, and Pacific Railroad (the Milwaukee Road ), the last transcontinental line to be built, electrified its lines across the Rocky Mountains and to the Pacific Ocean starting in 1915. A few East Coastlines, notably

2744-612: The Royal Scottish Society of Arts Exhibition in 1841. The seven-ton vehicle had two direct-drive reluctance motors , with fixed electromagnets acting on iron bars attached to a wooden cylinder on each axle, and simple commutators . It hauled a load of six tons at four miles per hour (6 kilometers per hour) for a distance of one and a half miles (2.4 kilometres). It was tested on the Edinburgh and Glasgow Railway in September of

2842-522: The SJ Class Dm 3 locomotives on Swedish Railways produced a record 7,200 kW. Locomotives capable of commercial passenger service at 200 km/h appeared in Germany and France in the same period. Further improvements resulted from the introduction of electronic control systems, which permitted the use of increasingly lighter and more powerful motors that could be fitted inside the bogies (standardizing from

2940-490: The Tughlakabad – Agra section. Earlier steam locomotive operated trains largely operated below 100 km/h (62 mph). With the introduction of electric locomotives in later 1920s and newer steam locomotives, speeds of 100 km/h (62 mph) were achieved. With the movement to AC traction in late 1950s and introduction of diesel locomotives , maximum speeds of up to 120 km/h (75 mph) were achieved in

3038-472: The United Kingdom (750 V and 1,500 V); Netherlands , Japan , Ireland (1,500 V); Slovenia , Belgium , Italy , Poland , Russia , Spain (3,000 V) and Washington, D.C. (750 V). Electrical circuits require two connections (or for three phase AC , three connections). From the beginning, the track was used for one side of the circuit. Unlike model railroads the track normally supplies only one side,

3136-574: The Virginian Railway and the Norfolk and Western Railway , electrified short sections of their mountain crossings. However, by this point electrification in the United States was more associated with dense urban traffic and the use of electric locomotives declined in the face of dieselization. Diesel shared some of the electric locomotive's advantages over steam and the cost of building and maintaining

3234-575: The WAM-1 locomotives, capable of reaching speeds of up to 112 km/h (70 mph). In 1960, the Railway Board of India commissioned a study to increase the speed of its trains, which was restricted to 96 km/h (60 mph) on the existent broad gauge lines. A target of 160 km/h (99 mph) with an intermediate stage of 120 km/h (75 mph) was set for passenger trains. Research Design and Standards Organisation (RDSO) started work on

3332-404: The traction motors to the wheels. Early locomotives often used jackshaft drives. In this arrangement, the traction motor is mounted within the body of the locomotive and drives the jackshaft through a set of gears. This system was employed because the first traction motors were too large and heavy to mount directly on the axles. Due to the number of mechanical parts involved, frequent maintenance

3430-522: The 1990s onwards on asynchronous three-phase motors, fed through GTO-inverters). In the 1980s, the development of very high-speed service brought further electrification. The Japanese Shinkansen and the French TGV were the first systems for which devoted high-speed lines were built from scratch. Similar programs were undertaken in Italy , Germany and Spain ; in the United States the only new mainline service

3528-482: The 56 km section of the Hungarian State Railways between Budapest and Komárom . This proved successful and the electrification was extended to Hegyeshalom in 1934. In Europe, electrification projects initially focused on mountainous regions for several reasons: coal supplies were difficult, hydroelectric power was readily available, and electric locomotives gave more traction on steeper lines. This

3626-531: The B&;O to the new line to New York through a series of tunnels around the edges of Baltimore's downtown. Parallel tracks on the Pennsylvania Railroad had shown that coal smoke from steam locomotives would be a major operating issue and a public nuisance. Three Bo+Bo units were initially used, the EL-1 Model. At the south end of the electrified section; they coupled onto the locomotive and train and pulled it through

3724-681: The Buchli drive was mainly used by the French SNCF and Swiss Federal Railways . The quill drive was also developed about this time and mounted the traction motor above or to the side of the axle and coupled to the axle through a reduction gear and a hollow shaft – the quill – flexibly connected to the driving axle. The Pennsylvania Railroad GG1 locomotive used a quill drive. Again, as traction motors continued to shrink in size and weight, quill drives gradually fell out of favor in low-speed freight locomotives. In high-speed passenger locomotives used in Europe,

3822-505: The First and Second World Wars. Diesel locomotives have less power compared to electric locomotives for the same weight and dimensions. For instance, the 2,200 kW of a modern British Rail Class 66 diesel locomotive was matched in 1927 by the electric SBB-CFF-FFS Ae 4/7 (2,300 kW), which is lighter. However, for low speeds, the tractive effort is more important than power. Diesel engines can be competitive for slow freight traffic (as it

3920-473: The London Underground. One setback for third rail systems is that level crossings become more complex, usually requiring a gap section. The original Baltimore and Ohio Railroad electrification used a sliding pickup (a contact shoe or simply the "shoe") in an overhead channel, a system quickly found to be unsatisfactory. It was replaced by a third rail , in which a pickup rides underneath or on top of

4018-537: The Ministry of Railways, express trains are classified as follows: a. Super-fast express: Any passenger train with an average speed higher than 55 km/h (34 mph) on 1,676 mm ( 5 ft 6 in ) broad gauge . b. Mail: Trains which earlier had a mail coach attached. Newer trains are not named so, but older trains remain in operation. c. Express: Express trains travel faster and have fewer stops than ordinary passenger trains. As of 2023 , it manages

4116-524: The Ministry of Railways, express trains travel faster and have limited stops than ordinary passenger trains. Any passenger train with an average speed higher than 55 km/h (34 mph) is considered super-fast. As of 2023 , India does not have any operational high-speed trains . The maximum operational speed of 160 km/h (99 mph) is achieved by Gatimaan Express and Rani Kamalapati (Habibganj)–Hazrat Nizamuddin Vande Bharat Express on

4214-567: The National Capital through the provision of non- air conditioned express trains with few stops and operating at high speeds. A similar capability had been introduced earlier on the Rajdhani express. However, these trains were completely air-conditioned and hence quite expensive . The Rajdhani and Shatabdi series are the fastest trains in India in terms of average journey speeds. The Sampark Kranti trains operate at slower average speeds than

4312-432: The Rajdhani and Shatabdi series yet still provide high speed options at normal prices due to their few stops and relatively faster speeds compared with other non- Rajdhani Express express trains and non- Shatabdi Express express trains although initially they ran non stop once they left their respective states. The Railway Minister (India) at the time Nitish Kumar in the interim Railway Budget of 2004-05 announced

4410-430: The amount of carbon monoxide, unburnt hydrocarbons, nitric oxides, and soot output from these mobile power sources. Because railroad infrastructure is privately owned in the U.S., railroads are unwilling to make the necessary investments for electrification. In Europe and elsewhere, railway networks are considered part of the national transport infrastructure, just like roads, highways and waterways, so are often financed by

4508-457: The boilers of some steam shunters , fed from the overhead supply, to deal with the shortage of imported coal. Recent political developments in many European countries to enhance public transit have led to another boost for electric traction. In addition, gaps in the unelectrified track are closed to avoid replacing electric locomotives by diesel for these sections. The necessary modernization and electrification of these lines are possible, due to

4606-761: The coach class and the second letter identifies the coach number. The berths and seats are numbered by an alphanumeric code with the letter(s) identifying the berth/seat type and numbers identifying the position. In standard coaches, the berths and seats are classified as follows: Indian Railways Operates various classes of Express trains . The trains are classified basis average speed and facilities with express trains having fewer halts, priority on rail network and faster average speed. The trains are identified by five digit numbers with train-pairs traveling in opposite directions usually labelled with consecutive numbers. Express trains often have specific unique names for easy identification. Rajdhani Express introduced in 1969 were

4704-699: The early 2010s. From the late 1990s, the ICF coaches were replaced by safer and newer LHB coaches designed by Linke-Hofmann-Busch of Germany . In the late 2010s, Indian railways started upgrading the coaches of select express trains from LHB to new Tejas coaches with enhanced features. As of March 2022, Indian Railways had 84,863 passenger coaches. Semi-high speed Train 18 was rolled out in 2018. These self-propelled EMU train sets manufactured by Integral Coach Factory are capable of reaching 180 kilometres per hour (110 mph). These trains have eight or sixteen coaches with driver cabins on both ends, which eliminates

4802-564: The early development of electric locomotion was driven by the increasing use of tunnels, particularly in urban areas. Smoke from steam locomotives was noxious and municipalities were increasingly inclined to prohibit their use within their limits. The first electrically worked underground line was the City and South London Railway , prompted by a clause in its enabling act prohibiting the use of steam power. It opened in 1890, using electric locomotives built by Mather and Platt . Electricity quickly became

4900-474: The electrification of many European main lines. European electric locomotive technology had improved steadily from the 1920s onwards. By comparison, the Milwaukee Road class EP-2 (1918) weighed 240 t, with a power of 3,330 kW and a maximum speed of 112 km/h; in 1935, German E 18 had a power of 2,800 kW, but weighed only 108 tons and had a maximum speed of 150 km/h. On 29 March 1955, French locomotive CC 7107 reached 331 km/h. In 1960

4998-501: The expo site at Frankfurt am Main West, a distance of 280 km. Using experience he had gained while working for Jean Heilmann on steam–electric locomotive designs, Brown observed that three-phase motors had a higher power-to-weight ratio than DC motors and, because of the absence of a commutator , were simpler to manufacture and maintain. However, they were much larger than the DC motors of

5096-738: The first main-line three-phase locomotives to the 40 km Burgdorf–Thun railway (highest point 770 metres), Switzerland. The first implementation of industrial frequency single-phase AC supply for locomotives came from Oerlikon in 1901, using the designs of Hans Behn-Eschenburg and Emil Huber-Stockar ; installation on the Seebach-Wettingen line of the Swiss Federal Railways was completed in 1904. The 15 kV, 50 Hz 345 kW (460 hp), 48 tonne locomotives used transformers and rotary converters to power DC traction motors. In 1894, Hungarian engineer Kálmán Kandó developed

5194-501: The first trains to reach speeds of up to 120 km/h (75 mph). Shatabdi Express , introduced in 1988, are capable of running at a maximum speed of 150 km/h (93 mph). In 2019, Vande Bharat Express was launched with self-propelled EMU train-sets capable of reaching maximum speed of 180 km/h (110 mph) with operational speeds restricted to 130–160 km/h (81–99 mph). A non-airconditioned semi-high speed train-set hauled by two modified WAP-5 locomotives

5292-399: The following year, but the limited power from batteries prevented its general use. It was destroyed by railway workers, who saw it as a threat to their job security. The first electric passenger train was presented by Werner von Siemens at Berlin in 1879. The locomotive was driven by a 2.2 kW, series-wound motor, and the train, consisting of the locomotive and three cars, reached

5390-432: The fourth largest national railway system by size with a track length of 132,310 km (82,210 mi), running track length of 106,493 km (66,172 mi) and route length of 68,584 km (42,616 mi). Track sections are rated for speeds ranging from 80 to 200 km/h (50 to 124 mph), though the maximum speed attained by passenger trains is 160 km/h (99 mph). In 2009, Indian Railways started

5488-454: The general or unreserved coaches. India has some of the lowest train fares in the world, and lower class passenger fares are subsidised. Discounted fares are applicable for railway employees, the differently-abled, students, athletes, patients and those taking competitive examinations. Seats of lower class of accommodation are reserved for women or senior citizens in some trains. Electric locomotive Electric locomotives benefit from

5586-999: The ground. The first electric locomotive built in 1837 was a battery locomotive. It was built by chemist Robert Davidson of Aberdeen in Scotland , and it was powered by galvanic cells (batteries). Another early example was at the Kennecott Copper Mine , McCarthy, Alaska , wherein 1917 the underground haulage ways were widened to enable working by two battery locomotives of 4 + 1 ⁄ 2 short tons (4.0 long tons; 4.1 t). In 1928, Kennecott Copper ordered four 700-series electric locomotives with onboard batteries. These locomotives weighed 85 short tons (76 long tons; 77 t) and operated on 750 volts overhead trolley wire with considerable further range whilst running on batteries. The locomotives provided several decades of service using nickel–iron battery (Edison) technology. The batteries were replaced with lead-acid batteries , and

5684-452: The high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking , which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there

5782-538: The implementation of regional high-speed rail projects to provide services at 250–350 km/h (160–220 mph), and planning for corridors connecting commercial, tourist, and pilgrimage hubs. On 25 July 2013, Government of India established the High Speed Rail Corporation for the implementation of high-speed rail corridor projects and in 2014, the Diamond Quadrilateral high speed rail project

6076-411: The late 1960s. With the introduction of high power electric locomotives in the 1990s, operating speeds of 130 km/h (81 mph) was achieved with further developments leading to speeds of maximum speeds of 160 km/h (99 mph) being realized in the early 2010s. Vande Bharat Express , an Electric Multiple Unit (EMU) run service introduced in 2019, is the fastest operational express train with

6174-520: The launch of Sampark Kranti Express. The trains in the Sampark Kranti series connect the Indian states to the national capital city of New Delhi . Sampark Kranti trains charge the same fare as regular/superfast trains on the Indian Railways rail network and do not provide any special facilities not available in regular Express trains . The initial decision of non-stop run of this Express series of trains

6272-1120: The locomotives were retired shortly afterward. All four locomotives were donated to museums, but one was scrapped. The others can be seen at the Boone and Scenic Valley Railroad , Iowa, and at the Western Railway Museum in Rio Vista, California. The Toronto Transit Commission previously operated on the Toronto subway a battery electric locomotive built by Nippon Sharyo in 1968 and retired in 2009. London Underground regularly operates battery–electric locomotives for general maintenance work. As of 2022 , battery locomotives with 7 and 14 MWh energy capacity have been ordered by rail lines and are under development. In 2020, Zhuzhou Electric Locomotive Company , manufacturers of stored electrical power systems using supercapacitors initially developed for use in trams , announced that they were extending their product line to include locomotives. Electrification

Express trains stop at select set of stations identified using a combination of factors including commercial importance, traffic and capabilities. Indian Railways offers various travel classes on its coaches . For the purpose of identification in passenger trains , coaches in a train-set are assigned an alpha-numeric code. The first letter identifies

6468-619: The operational speed of the passenger trains to 160 km/h (99 mph). In 2014, the Diamond Quadrilateral high-speed rail network project was launched by Government of India and is envisioned to connect the four major metro cities of India namely: Chennai, Delhi, Kolkata and Mumbai. The Ministry of Railways envisaged to have dedicated standard gauge tracks capable of top speeds of 300–350 km/h (190–220 mph) with trains running on elevated corridors to isolate high-speed train tracks by 2026 and identified probable routes for

6566-434: The other side(s) of the circuit being provided separately. Railways generally tend to prefer overhead lines , often called " catenaries " after the support system used to hold the wire parallel to the ground. Three collection methods are possible: Of the three, the pantograph method is best suited for high-speed operation. Some locomotives use both overhead and third rail collection (e.g. British Rail Class 92 ). In Europe,

6664-406: The passenger and fare details along with berth or seat number(s) allocated to them on the ticket. In case of no confirmed reservation, a wait-list number is assigned and wait-listed tickets get confirmed if there are cancellations of already reserved tickets. Reservation against cancellation tickets is an intermediate category between the waiting and confirmed lists in sleeper classes which allows

6762-424: The performance of AC locomotives was sufficiently developed to allow all its future installations, regardless of terrain, to be of this standard, with its associated cheaper and more efficient infrastructure. The SNCF decision, ignoring as it did the 2,000 miles (3,200 km) of high-voltage DC already installed on French routes, was influential in the standard selected for other countries in Europe. The 1960s saw

6860-490: The period of electrification of the Italian railways, tests were made as to which type of power to use: in some sections there was a 3,600 V 16 + 2 ⁄ 3  Hz three-phase power supply, in others there was 1,500 V DC, 3 kV DC and 10 kV AC 45 Hz supply. After WW2, 3 kV DC power was chosen for the entire Italian railway system. A later development of Kandó, working with both

6958-567: The power required for ascending trains. Most systems have a characteristic voltage and, in the case of AC power, a system frequency. Many locomotives have been equipped to handle multiple voltages and frequencies as systems came to overlap or were upgraded. American FL9 locomotives were equipped to handle power from two different electrical systems and could also operate as diesel–electrics. While today's systems predominantly operate on AC, many DC systems are still in use – e.g., in South Africa and

7056-597: The power supply infrastructure, which discouraged new installations, brought on the elimination of most main-line electrification outside the Northeast. Except for a few captive systems (e.g. the Deseret Power Railroad ), by 2000 electrification was confined to the Northeast Corridor and some commuter service; even there, freight service was handled by diesel. Development continued in Europe, where electrification

7154-530: The power supply of choice for subways, abetted by Sprague's invention of multiple-unit train control in 1897. Surface and elevated rapid transit systems generally used steam until forced to convert by ordinance. The first use of electrification on an American main line was on a four-mile stretch of the Baltimore Belt Line of the Baltimore and Ohio Railroad (B&O) in 1895 connecting the main portion of

7252-400: The quill drive is still predominant. Another drive was the " bi-polar " system, in which the motor armature was the axle itself, the frame and field assembly of the motor being attached to the truck (bogie) in a fixed position. The motor had two field poles, which allowed a limited amount of vertical movement of the armature. This system was of limited value since the power output of each motor

7350-420: The recommended geometry and shape of pantographs are defined by standard EN 50367/IEC 60486 Mass transit systems and suburban lines often use a third rail instead of overhead wire. It allows for smaller tunnels and lower clearance under bridges, and has advantages for intensive traffic that it is a very sturdy system, not sensitive to snapping overhead wires. Some systems use four rails, especially some lines in

7448-514: The same in 1962 with field trials commencing in 1967. The coaches were manufactured by the Integral Coach Factory at Madras and hauled by diesel locomotives . On 19 February 1969, the Government of India announced the introduction of a new express train capable of reaching speeds of up to 120 km/h (75 mph) in the railway budget . On 1 March 1969, the first Rajdhani Express

7546-452: The same. A 174 km (108 mi) segment of track in the Tughlakabad – Agra Cantonment section supports semi-high speed passenger traffic of up to 160 km/h (99 mph). The early express rail coaches were based on a prototype by a Swiss company and were termed as ICF coaches after Integral coach factory (ICF), the first coach manufacturing unit in India. These coaches, manufactured from 1955 to 2018, were largely in use till

7644-439: The state. Operators of the rolling stock pay fees according to rail use. This makes possible the large investments required for the technically and, in the long-term, also economically advantageous electrification. The first known electric locomotive was built in 1837 by chemist Robert Davidson of Aberdeen , and it was powered by galvanic cells (batteries). Davidson later built a larger locomotive named Galvani , exhibited at

7742-442: The stations by commercial importance into three different categories namely Non Suburban Group (NSG), Suburban Group (SG) and Halt Group (HG). These are further subdivided into subcategories based on their commercial importance (NSG 1-6, SG 1-3 and from HG 1-3). The commercial importance of a station is determined by taking into account its passenger footfall, earnings and strategic importance and these categories are used to determine

7840-399: The stator circuit, with acceleration controlled by switching additional resistors in, or out, of the rotor circuit. The two-phase lines are heavy and complicated near switches, where the phases have to cross each other. The system was widely used in northern Italy until 1976 and is still in use on some Swiss rack railways . The simple feasibility of a fail-safe electric brake is an advantage of

7938-442: The system, while speed control and the two-phase lines are problematic. Rectifier locomotives, which used AC power transmission and DC motors, were common, though DC commutators had problems both in starting and at low velocities. Today's advanced electric locomotives use brushless three-phase AC induction motors . These polyphase machines are powered from GTO -, IGCT - or IGBT -based inverters. The cost of electronic devices in

8036-600: The time and could not be mounted in underfloor bogies : they could only be carried within locomotive bodies. In 1896, Oerlikon installed the first commercial example of the system on the Lugano Tramway . Each 30-tonne locomotive had two 110 kW (150 hp) motors run by three-phase 750 V 40 Hz fed from double overhead lines. Three-phase motors run at a constant speed and provide regenerative braking and are thus well suited to steeply graded routes; in 1899 Brown (by then in partnership with Walter Boveri ) supplied

8134-477: The time needed for turnaround at the terminal station with faster acceleration and deceleration, enabling the train to travel at a top speed for longer distance. Coaches are manufactured by five manufacturing units of the Indian Railways and public sector companies BEML and BHEL. The coaching stock have unique five or six digit identifiers. Till 2018, the first two digits indicating the year of manufacture and

8232-640: The tunnels. Railroad entrances to New York City required similar tunnels and the smoke problems were more acute there. A collision in the Park Avenue tunnel in 1902 led the New York State legislature to outlaw the use of smoke-generating locomotives south of the Harlem River after 1 July 1908. In response, electric locomotives began operation in 1904 on the New York Central Railroad . In the 1930s,

8330-443: The use of low currents; transmission losses are proportional to the square of the current (e.g. twice the current means four times the loss). Thus, high power can be conducted over long distances on lighter and cheaper wires. Transformers in the locomotives transform this power to a low voltage and high current for the motors. A similar high voltage, low current system could not be employed with direct current locomotives because there

8428-576: Was an extension of electrification over the Northeast Corridor from New Haven, Connecticut , to Boston, Massachusetts , though new electric light rail systems continued to be built. On 2 September 2006, a standard production Siemens electric locomotive of the Eurosprinter type ES64-U4 ( ÖBB Class 1216) achieved 357 km/h (222 mph), the record for a locomotive-hauled train, on the new line between Ingolstadt and Nuremberg. This locomotive

8526-513: Was approved by the government. In April 2016, the WAP-5 hauled Gatimaan Express became the fastest commercial train in India, with a maximum operational speed of 160 km/h (99 mph). In 2018, Integral Coach Factory in Chennai, rolled out a semi-high-speed EMU train-set , capable of reaching 180 km/h (110 mph). In 2019, the first Vande Bharat Express entered commercial service with

8624-453: Was cut short and was given way to commercial stopping outside the states. The trains aim at reducing travel time without compromising on passenger comfort. Initially eighteen trains were launched and the count was later increased. The Karnataka Sampark Kranti Express from Delhi Hazrat Nizamuddin to Yesvantpur was the first train which was launched on 8 February 2004. Uttar Pradesh Sampark Kranti Express link from Khajuraho got terminated with

8722-667: Was done manually. Centralized computer reservation system was deployed in September 1996. The ticketing network at stations is computerized with the exception of few stations. The Indian Railways website went online in February 2000 and online ticketing was introduced on 3 August 2002 through IRCTC. Indian Railways now provides multiple channels for passengers to book tickets through website , smartphone apps , SMS , rail reservation counters at train stations, or through private ticket booking counters. Reserved tickets may be booked up to 60 days in advance and confirmed reservation tickets will show

8820-487: Was flagged off from New Delhi to Howrah , which reached a maximum speed of 120 km/h (75 mph) and completed the 1,450 km (900 mi) trip in 17 hours 20 minutes at an average speed of 84 km/h (52 mph). In 1980, the WAP-1 electric locomotives capable of reaching speeds of 130 km/h (81 mph) were introduced to haul express trains. Shatabdi Express introduced in 1988, were capable of running at

8918-1043: Was launched as Amrit Bharat Express . A high-speed rail line is under-construction between Mumbai and Ahmedabad which will become the first true high-speed rail line when completed in 2026. As of 2023 , the maximum operational speed of 160 km/h (99 mph) is achieved by Gatimaan Express and Vande Bharat Express on the above section. India Railways operates various categories of express trains including Vande Bharat Express , Rajdhani Express , Shatabdi Express , Amrit Bharat Express , Garib Rath Express , Double Decker Express , Tejas Express , Gatimaan Express , Humsafar Express , Duronto Express , Yuva Express , Uday Express , Jan Shatabdi Express , Sampark Kranti Express , Vivek Express , Rajya Rani Express , Mahamana Express , Antyodaya Express , Jan Sadharan Express , Suvidha Express and Intercity Express . As of 2022 , Indian Railways operated 2,999 express trains on average daily. In 1986, computerized ticketing and reservations were introduced before which ticketing

9016-404: Was limited. The EP-2 bi-polar electrics used by the Milwaukee Road compensated for this problem by using a large number of powered axles. Modern freight electric locomotives, like their Diesel–electric counterparts, almost universally use axle-hung traction motors, with one motor for each powered axle. In this arrangement, one side of the motor housing is supported by plain bearings riding on

9114-399: Was necessary. The jackshaft drive was abandoned for all but the smallest units when smaller and lighter motors were developed, Several other systems were devised as the electric locomotive matured. The Buchli drive was a fully spring-loaded system, in which the weight of the driving motors was completely disconnected from the driving wheels. First used in electric locomotives from the 1920s,

9212-498: Was not available. DC locomotives typically run at relatively low voltage (600 to 3,000 volts); the equipment is therefore relatively massive because the currents involved are large in order to transmit sufficient power. Power must be supplied at frequent intervals as the high currents result in large transmission system losses. As AC motors were developed, they became the predominant type, particularly on longer routes. High voltages (tens of thousands of volts) are used because this allows

9310-457: Was particularly applicable in Switzerland, where almost all lines are electrified. An important contribution to the wider adoption of AC traction came from SNCF of France after World War II . The company had assessed the industrial-frequency AC line routed through the steep Höllental Valley , Germany, which was under French administration following the war. After trials, the company decided that

9408-513: Was the first in the world in regular service powered from an overhead line. Five years later, in the U.S. electric trolleys were pioneered in 1888 on the Richmond Union Passenger Railway , using equipment designed by Frank J. Sprague . The first electrified Hungarian railway lines were opened in 1887. Budapest (See: BHÉV ): Ráckeve line (1887), Szentendre line (1888), Gödöllő line (1888), Csepel line (1912). Much of

9506-506: Was three-phase at 3 kV 15 Hz. The voltage was significantly higher than used earlier and it required new designs for electric motors and switching devices. The three-phase two-wire system was used on several railways in Northern Italy and became known as "the Italian system". Kandó was invited in 1905 to undertake the management of Società Italiana Westinghouse and led the development of several Italian electric locomotives. During

9604-530: Was widespread. 1,500 V DC is still used on some lines near France and 25 kV 50 Hz is used by high-speed trains. The first practical AC electric locomotive was designed by Charles Brown , then working for Oerlikon , Zürich. In 1891, Brown had demonstrated long-distance power transmission for the International Electrotechnical Exhibition , using three-phase AC , between a hydro–electric plant at Lauffen am Neckar and
