68-479: Turnstiles were originally used, like other forms of stile , to allow human beings to pass while keeping sheep or other livestock penned in. The use of turnstiles in most modern applications has been credited to Clarence Saunders , who used them in his first Piggly Wiggly store. Turnstiles are used at a wide variety of settings, including stadiums, amusement parks, mass transit stations, office lobbies, airports, ski resorts, factories, power plants and casinos. From

136-569: A 54% increase in weekday riders since 1992. On the other hand, weekday ridership on the South Side portion of the Green Line, which closed for two years for reconstruction from January 1994 to May 1996, was 50,400 in 1978 but only 13,000 in 2006. Boardings at the 95th/Dan Ryan stop on the Red Line, though still among the system's busiest at 11,100 riders per weekday as of February 2015, are less than half

204-413: A business/revenue standpoint, turnstiles give an accurate, verifiable count of attendance. From a security standpoint, they lead patrons to enter single-file, so security personnel have a clear view of each patron. This enables security to efficiently isolate potential trouble or to confiscate any prohibited materials. On the other hand, physical barriers become a serious safety issue when a speedy evacuation

272-740: A couple of dozen people, departed the 39th Street station and arrived at the Congress Street Terminal 14 minutes later, over tracks that are still in use by the Green Line. Over the next year, service was extended to 63rd Street and Stony Island Avenue , then the Transportation Building of the World's Columbian Exposition in Jackson Park . In 1893, trains began running on the Lake Street Elevated Railroad and in 1895 on

340-657: A flat fare of $ 2.50 for almost the entire system, the only exception being O'Hare International Airport on the Blue Line, at which passengers entering the station are charged a higher fare of $ 5.00 (passengers leaving the system at this station are not charged this higher fare). The higher fare is being charged for what the CTA considers "premium-level" service to O'Hare. Use of the Midway International Airport Station does not require this higher fare; it only requires

408-407: A line of turnstiles may be entirely formed of wide aisle gates, for example at Heathrow Terminals 2 & 3 Underground station . Turnstiles often use ratchet mechanisms to allow the rotation of the stile in one direction allowing ingress but preventing rotation in the other direction. They are often designed to operate only after a payment has been made, usually by inserting a coin or token in

476-617: A publisher's editor in New York or some other east coast city; in Chicago the same expression is routinely rendered 'L'." As used by CTA, the name is rendered as the capital letter 'L', in single quotation marks. "L" (with double quotation marks) was often used by CTA predecessors such as the Chicago Rapid Transit Company; however, the CTA uses single quotation marks (') on some printed materials and signs rather than double. In Chicago,

544-784: A quarter-mile apart. The CTA introduced fare cards for the first time in 1997. Rail service to the O'Hare International Airport first opened in 1984 and to the Midway International Airport in 1993. That same year, the CTA renamed all of its rail lines; they are now identified by color. Later, after assuming control of the "L", the CTA introduced A/B skip-stop service. Under this service, trains were designated as either "A" or "B" trains, and stations were alternately designated as "A" stations or "B" stations, with heavily used stations designated as both – "AB". "A" trains would stop only at "A" and "AB" stations, and "B" trains would stop only at "B" and "AB" stations. Station signage carried

612-401: A slot; or by swiping, tapping, or inserting a paper ticket or electronically-encoded card. Turnstiles are often used for counting the numbers of people passing through a gate, even when payment is not involved. They are used extensively in this manner in amusement parks , in order to keep track of how many people enter and exit the park and ride each ride. The first major use of turnstiles at

680-539: A sporting venue was at Hampden Park in Glasgow , Scotland . Waist-high turnstiles are often used in fairs, attractions, and arenas. The user inserts a ticket or pass into the slot, from which a barcode is read; if access is to be granted, a sensor determines the speed with which the user passes through, and sets the electric motor to turn the turnstile at the corresponding speed. Sometimes also referred to as "half-height" turnstiles, this fixed arm style has traditionally been

748-517: A station reconstruction project to accommodate longer trains. Annual traffic on the Howard branch of the Red Line, which reached 38.7 million in 2010 and 40.9 million in 2011, has exceeded the 1927 prewar peak of 38.5 million. The section of the Blue Line between the Loop and Logan Square , which serves once-neglected but now bustling neighborhoods such as Wicker Park , Bucktown , and Palmer Square , has seen

816-531: A third. By the 1950s, the service was used throughout the system. All lines used the A/B skip-stop service between the 1950s and the 1990s with the exception of the Evanston and Skokie lines, which were suburban-only lines and did not justify skip-stop service. On the lines with branches, skip-stop service sent all "A" trains to one branch and "B" trains to another branch. On what became the Blue Line, "A" trains were routed on

884-581: A variety of forms (as is also the case in the US, where there is no standard). As well as having a variety of forms, modern stiles also sometimes include a 'dog latch' or 'dog gate' to the side of them, which can be lifted to enable a dog to get through. Where footpaths cross dry stone walls in England a squeeze stile is sometimes found, a vertical gap in the wall, usually no more than 25 centimetres (9.8 in) wide, often formed by stone pillars on either side to protect

952-488: Is a structure or opening that provides passage for humans – rather than animals such as livestock  – over or through a boundary. Common forms include steps , ladders , or narrow gaps. Stiles are often built in rural areas along footpaths , fences , walls , or hedges that enclose domestic animals. In the United Kingdom many stiles were built under legal compulsion (see Rights of way in

1020-545: Is currently focused on eliminating slow zones, modernizing the Red, Blue, and Purple lines, and improving "L" stations. In addition, CTA has studied numerous other proposals for expanded rail service and renovations, some of which may be implemented in the future. During the 2000s and 2010s, the CTA has completed several renovation and new construction projects. Pink Line service began on June 25, 2006, though it did not include any new tracks or stations. The Pink Line travels over what

1088-527: Is granted the arms drop into recesses in the cabinet. Once the arms drop out of the way, the turnstile functions as a fully optical turnstile. The full-height turnstile – a larger version of the waist-high turnstile, commonly 7 feet (2.1 m) high – , is based on the same principle as the revolving door . Furthermore, full-height turnstiles offer better security inasmuch as they can neither be climbed over nor ducked under, and can be designed to lock after each person enters such that

1156-470: Is needed, requiring emergency exits that bypass any turnstiles. The ticket barriers on the London Underground and some busy UK railway stations have to be open if either the gates are unmanned or in an emergency. Persons with disabilities may have difficulties using turnstiles. In these cases, generally a wide aisle gate or a manual gate may be provided. At some locations where luggage is expected,

1224-548: Is people can " jump the turnstile " as happens commonly on the Moscow Metro and other mass transport systems in Russia . The wall mount tripod turnstiles are suitable for places where installation on ground becomes impossible. The turnstile is directly fixed to the wall and all functions are achieved. Such turnstiles are usually used in narrow lanes and where wall installation is more feasible. Optical turnstiles are an alternative to

1292-588: The Chicago Rapid Transit Company until 1924. He also bought three other Chicago electrified railroads, the Chicago North Shore and Milwaukee Railroad , Chicago Aurora and Elgin Railroad , and South Shore interurban lines, and ran the trains of the first two into downtown Chicago via the "L" tracks. This period of relative prosperity ended when Insull's empire collapsed in 1932, but later in

1360-759: The Green Line , the Purple Line and the Douglas branch of the Blue Line (the modern-day Pink Line ) also had 24 hour service. In the years of private ownership, the South Side Elevated Railroad (now the South Side Elevated portion of the Green Line) provided 24 hour service, a major advantage when compared to Chicago's cable railroads which required daily overnight shutdown for cable maintenance. In 2015,

1428-615: The Metropolitan West Side Elevated , which had lines to Douglas Park, Garfield Park (since replaced), Humboldt Park (since demolished), and Logan Square. The Metropolitan was the United States' first non-exhibition rapid transit system powered by electric traction motors , a technology whose practicality had been demonstrated in 1890 on the "intramural railway" at the World Fair that had been held in Chicago. Two years later

1496-667: The "L", and of Chicago mass transit in general, had become too precarious to permit continued operation without subsidies, and the necessary steps were taken to enable a public takeover. In 1947, the Chicago Transit Authority (CTA) acquired the assets of the Chicago Rapid Transit Company and the Chicago Surface Lines , operator of the city's streetcars. Over the next few years CTA modernized the "L", replacing wooden cars with new steel ones and closing lightly used branch lines and stations , many of which had been spaced only

1564-659: The "seven wonders of Chicago", behind the lakefront and Wrigley Field , and ahead of Willis Tower (formerly the Sears Tower), the Water Tower , the University of Chicago , and the Museum of Science and Industry . The first "L", the Chicago and South Side Rapid Transit Railroad , began revenue service on June 6, 1892, when a steam locomotive pulling four wooden coaches, carrying more than

1632-611: The $ 2.50 regular fare. The higher charge at O'Hare has been the source of some controversy in recent years, because of the CTA's plan to eliminate the exemption from the premium fare for airport workers, Transportation Security Administration workers, and airline workers. After protests from those groups, the CTA extended the exemptions for six months. Since 1993, "L" lines have been officially identified by color, although older route names survive to some extent in CTA publications and popular usage to distinguish branches of longer lines. Stations are found throughout Chicago, as well as in

1700-473: The 1920s. After 1911, the "L" lines came under the control of Samuel Insull , president of the Chicago Edison electric utility (now Commonwealth Edison ), whose interest stemmed initially from the fact that the trains were the city's largest consumer of electricity. Insull instituted many improvements, including free transfers and through routing, although he did not formally combine the original firms into

1768-483: The 1990s, use of the A/B skip-stop system was only used during rush hour service. Another problem was that trains skipping stations to save time still could not pass the train that was directly ahead, so skipping stations was not advantageous in all regards. In 1993, the CTA began to eliminate skip-stop service when it switched the southern branches of the West-South and North-South Lines to improve rider efficiency, creating

1836-452: The 3200-series and 5000-series. The design and arrangement of seats were modified to improve ergonomics and increase leg room. Enhanced air conditioning will circulate air more efficiently during hot summer days. Laser sensors above the doors will count the number of passengers, allowing the CTA to track passenger volumes and change its schedules accordingly. State-owned manufacturer CRRC Sifang America (China Rail Rolling Stock Corporation) won

1904-454: The 7000-series cars commenced in June 2019. This is the first time in more than 50 years CTA rail cars are manufactured in Chicago. Ten cars in the 7000-series began testing revenue service on April 21, 2021. The base order is for 400 cars and will be used to replace the 2600-series cars. If the CTA ordered the additional 446 cars, they would also replace the 3200-series cars. In May 2023,

1972-479: The CTA announced it has received $ 200 million funding from the Federal Transit Authority; this money will go towards the development of the 9000-series rail cars. The plan is to acquire up to 300 new train sets. Chicago's rapid-transit system is officially nicknamed the "L". This name for the CTA rail system applies to the whole system: its elevated, subway, at-grade, and open-cut segments. The use of

2040-460: The CTA introduced a new fare payment system called Ventra . Ventra enables passengers to purchase individual tickets, passes, or transit value online, by smart phone, or at participating retail locations. Ventra also works with CTA buses, Pace (suburban buses), and Metra (commuter rail). Payment by a smartphone app, the Ventra app, or by a contactless bankcard is possible. As of 2018 , the "L" uses

2108-681: The Congress branch while "B" trains were sent to the Douglas branch. On the North-South Line, "A" trains went to the Englewood branch and "B" trains went to the Jackson Park branch. In both cases, individual stops were not skipped beyond the points where those branches diverged. As time went by, the time periods which employed skip-stop service gradually decreased, as the waits at "A" and "B" stations became increasingly longer during non-peak service. By

2176-636: The Milwaukee elevated into the Kennedy Expressway in 1970. As of 2014, Chicago "L" trains run over a total of 224.1 miles (360.7 km) of track. Ridership has been growing steadily after the CTA takeover despite declining mass transit usage nationwide, with an average of 594,000 riders boarding each weekday in 1960 and 759,866 in 2016 (or 47% of all CTA rides). Due to the Loop Flood in April 1992, ridership

2244-550: The Red Line Dan Ryan branch reconstruction. The Brown Line Capacity Expansion Project enabled CTA to run eight-car trains on the Brown Line, and rebuilt stations to modern standards, including accessibility. Before the project, Brown Line platforms could only accommodate six-car trains, and increasing ridership led to uncomfortably crowded trains. After several years of construction, eight-car trains began to run at rush hour on

2312-485: The Red and Blue Lines, making Chicago, New York City, and Copenhagen the only three cities in the world to offer 24-hour train service on some of their lines throughout their respective city limits. The oldest sections of the Chicago "L" started operations in 1892, making it the second-oldest rapid transit system in the Americas, after New York City's elevated lines . The "L" gained its name from "el" because large parts of

2380-405: The South Side "L" introduced multiple-unit control , in which the operator can control all the motorized cars in a train, not just the lead unit. Electrification and MU control remain standard features of most of the world's rapid transit systems. A drawback of early "L" service was that none of the lines entered the central business district. Instead trains dropped passengers at stub terminals on

2448-490: The United Kingdom ). Recent changes in UK government policy towards farming have encouraged upland landowners to make access more available to the public, and this has seen an increase in the number of stiles and an improvement in their overall condition. However stiles are deprecated and are increasingly being replaced by gates or kissing gates or, where the field is arable, the stile removed. Many legacy stiles remain, however, in

2516-454: The city's streetcar system, obtained the necessary signatures through cash and guile—at one point he secured a franchise to build a mile-long "L" over Van Buren Street from Wabash Avenue to Halsted Street, extracting the requisite majority from the pliable owners on the western half of the route, then building tracks chiefly over the eastern half, where property owners had opposed him. Designed by noted bridge builder John Alexander Low Waddell ,

2584-420: The close spacing of the support columns (a more extensive plan proposed replacing the entire elevated system with subways). The subways bypassed a number of tight curves and circuitous routings on the original elevated lines (Milwaukee trains, for example, originated on Chicago's northwest side but entered the Loop at the southwest corner), speeding service for many riders. By the 1940s, the financial condition of

With 509 cars in operation, the 2600-series is the largest of the three series of "L" cars in operation. The cars were rebuilt by Alstom of Hornell, New York , from 1999 until 2002. The 3200-series , was built from 1992 until 1994 by Morrison-Knudsen of Hornell, New York. These cars have fluted, stainless steel sides similar to

The cars are being built at a new CRRC Sifang America rail car manufacturing plant at 13535 South Torrence Avenue in Chicago's Hegewisch neighborhood. Production of

2788-413: The conversion of the O'Hare branch of the Blue Line and the Howard branch of the Red Line to all-stop service. The removal of skip-stop service resulted in some increases in travel times, and greatly increased ridership at former "A" and "B" stations due to increased train frequencies. Station signage highlighting the former skip-stop patterns would remain into the 2000s, when it was gradually replaced across

2856-402: The current Red and Green Lines. From this point, Green Line trains made all stops along the entire route, while Red Line trains stopped at all stations south of Harrison . The elimination of A/B skip-stop service continued with the opening of the all-stop Orange Line and the conversion of the Brown Line to all-stop service. In April 1995, the last of the A/B skip-stop system was eliminated with

2924-432: The decade the city with the help of the federal government accumulated sufficient funds to begin construction of two subway lines to supplement and, some hoped, permit eventual replacement of the Loop elevated; as early as the 1920s some city leaders wanted to replace the "ugly" elevated tracks and these plans advanced in the 1970s under mayors Richard J. Daley and Michael Bilandic until a public outcry against tearing down

2992-616: The elevated tracks used a multiple close-rivet system to withstand the forces of the passing trains' kinetic energy. The Union Loop opened in 1897 and greatly increased the rapid transit system's convenience. Operation on the Yerkes-owned Northwestern Elevated , which built the North Side "L" lines, began three years later, essentially completing the elevated infrastructure in the urban core although extensions and branches continued to be constructed in outlying areas through

It is sometimes called a "rotogate", especially in Chicago, where it is used at unstaffed exits of Chicago "L" stations, and is also used increasingly in New York City Subway stations since the turn of the 21st century. Stile A stile

3128-611: The highest level since the station opened in 1969. The 2003 Chicago Central Area Plan proposed construction of a Green Line station at Cermak , between Chinatown and the McCormick Place convention center, in expectation of continued density growth in the vicinity. This station opened in 2015. Currently, the Red Line and the Blue Line provide 24-hour service, while all other lines operate from early morning to late night. Prior to 1998,

3196-610: The line opened. In discussing various stylings of "Loop" and "L" in Destination Loop: The Story of Rapid Transit Railroading in and around Chicago (1982), author Brian J. Cudahy quotes a passage from The Neon Wilderness (1947) by Chicago author Nelson Algren : "beneath the curved steel of the El, beneath the endless ties." Cudahy then comments, "Note that in the quotation above ... it says 'El' to mean 'elevated rapid transit railroad.' We trust that this usage can be ascribed to

3264-399: The most popular type of turnstile. There are many variations of this style available, including one which is designed to be accompanied by a matching ticket box, and one with a ticket box built in. Some styles are designed to allow entry only after a payment (actual coins and tokens) are inserted, while others allow access after a valid barcode is electronically read. A disadvantage to this type

3332-404: The nickname dates from the earliest days of the elevated railroads. Newspapers of the late 1880s referred to proposed elevated railroads in Chicago as " 'L' roads." The first route to be constructed, the Chicago and South Side Rapid Transit Railroad gained the nickname "Alley Elevated", or "Alley L" during its planning and construction, a term that was widely used by 1893, less than a year after

3400-551: The now-retired 2200-series . The 5000-series train cars are equipped with AC propulsion; interior security cameras; aisle-facing seating, which allow for greater passenger capacity; LED destination signs, interior readouts, and interior maps; GPS; glow-in-the-dark evacuation signs; operator-controlled ventilation systems; among other features. AC propulsion allows for smoother acceleration, lower operational costs, less wear and tear, and greater energy efficiency. The AC propulsion can take advantage of regenerative braking , meaning

3468-505: The peak volume in the 1980s. In 1976, three North Side "L" branches – what were then known as the Howard, Milwaukee, and Ravenswood lines − accounted for 42% of non-downtown boardings. Today (with the help of the Blue Line extension to O'Hare), they account for 58%. The North Side, which has historically been the highest density area of the city, reflects the Chicago building boom between 2000 and 2010, which has focused primarily on North Side neighborhoods and downtown. It may ease somewhat in

This obstacle was overcome by the legendary traction magnate Charles Tyson Yerkes , who went on to play a pivotal role in the development of the London Underground , and who was immortalized by Theodore Dreiser as the ruthless schemer Frank Cowperwood in The Titan (1914) and other novels. Yerkes, who controlled much of

3604-463: The popular "L" began, led by Chicago Tribune columnist Paul Gapp , and architect Harry Weese . Instead, then new Mayor Jane Byrne protected the elevated lines and directed their rehabilitation. The State Street subway opened on October 17, 1943. The Dearborn Subway, on which work had been suspended during World War II , opened on February 25, 1951. The subways were constructed with a secondary purpose of serving as bomb shelters, as evidenced by

3672-460: The post-World-War era growth of the expressway ; its general use of alleyways instead of streets throughout its history, and expressway mediums after the war, better knit the system into the city, and in pioneering ways. It consists of eight rapid transit lines laid out in a spoke–hub distribution paradigm focusing transit towards the Loop . In a 2005 poll, Chicago Tribune readers voted it one of

The system was designed to speed up lines by having trains skip stations while still allowing for frequent service at the heavily used "AB" stations. A/B skip-stop service debuted on the Lake Street Elevated in 1948, and the service proved effective as travel times were cut by

3808-502: The structure of the wall. Chicago %22L%22 The Chicago " L " (short for " elevated ") is the rapid transit system serving the city of Chicago and some of its surrounding suburbs in the U.S. state of Illinois . Operated by the Chicago Transit Authority (CTA), it is the fourth-largest rapid transit system in the United States in terms of total route length, at 102.8 miles (165.4 km) long as of 2014, and

3876-496: The suburbs of Forest Park , Oak Park , Evanston , Wilmette , Cicero , Rosemont , and Skokie . The CTA operates over 1,350 "L" cars, divided among four series, all of which are semi-permanently coupled into married pairs. All cars on the system utilize 600- volt direct current power delivered through a third rail . The 2600-series was built from 1981 until 1987 by the Budd Company of Philadelphia , Pennsylvania.

By October 2008, system-wide slow zones had been reduced to 9.1% and by January 2010, total slow zones were reduced to 6.3%. CTA's Slow Zone Elimination Project is an ongoing effort to restore track work to conditions where trains no longer have to reduce speeds through deteriorating areas. The Loop received track work in 2012–2013. The Purple Line in Evanston received track work and viaduct replacement in 2011–2013. The Green Line Ashland branch received track work in 2013, prior to

The "L" has been credited for fostering the growth of Chicago's dense city core that is one of the city's distinguishing features. And according to urban engineer Christof Speiler, the system stands out in the United States because it continued to invest in services even through

New lines were built in expressway medians, a technique implemented in Chicago and followed by other cities worldwide. The Congress branch, built in the median of the Eisenhower Expressway, replaced the Garfield Park "L" in 1958. The Dan Ryan branch, built in the median of the Dan Ryan Expressway, opened on September 28, 1969, followed by an extension of

As of January 2024, the "L" had 1,480 rail cars operating across eight different routes on 224.1 miles of track. CTA trains make about 1,888 trips each day servicing 146 train stations. In 2023, the system had 117,447,000 rides, or about 416,200 per weekday in the third quarter of 2024. The "L" provides 24-hour service on

Optical turnstiles generally use an infrared beam to count patrons and recognize anyone attempting to enter a site without a valid entry pass. The drop-arm optical turnstile is a combination of the security of a tripod or barrier turnstile and a fully optical turnstile. The lanes can have either single or double arms. When access

With the DC propulsion of the previous series, they utilize dynamic braking which converts the excess kinetic energy into heat within a resistor bank. Next-generation train cars, the 7000-series , have been ordered and are beginning to enter service. Each 7000-series rail car will feature LEDs, 37 to 38 seats, and is a hybrid of

4420-510: The wake of the current high level of residential construction along the south lakefront. For example, ridership at the linked Roosevelt stops on the Green, Orange, and Red Lines, which serve the burgeoning South Loop neighborhood, has tripled since 1992, with an average of 8,000 boardings per weekday. Patronage at the Cermak- Chinatown stop on the Red Line, with 4,000 weekday boardings, is at

Growing ridership has not been uniformly distributed. Use of North Side lines is heavy and continues to grow, while that of West Side and South Side lines tend to remain stable. Ridership on the North Side Brown Line, for instance, has increased 83% since 1979, necessitating
