The '''Chicago Transit Authority''' ('''CTA''') is the operator of [[public transport|mass transit]] in [[Chicago]], Illinois, United States, and some of its [[suburbs]], including the trains of the [[Chicago "L"]] and [[List of Chicago Transit Authority bus routes|CTA bus service]]. In {{American transit ridership|annualdate}}, the system had a ridership of 650,200,800, or about 1,781,372 per weekday as of 2024.

The CTA is an [[Illinois]] [[Government agency|independent governmental agency]]<ref>{{cite web|title=CTA Facts at a Glance|url=http://www.transitchicago.com/about/facts.aspx|access-date=October 20, 2014|publisher=Chicago Transit Authority|location=[[Chicago]]}}</ref> that started operations on October 1, 1947, upon the purchase and combination of the transportation assets of the [[Chicago Rapid Transit Company]] and the [[Chicago Surface Lines]] streetcar system. In 1952, CTA purchased the assets of the [[Chicago Motor Coach Company]], which was under the control of [[Yellow Cab Company]] founder [[John D. Hertz]], resulting in a fully unified system. Today, the CTA is one of the three service boards financially supported by the [[Regional Transportation Authority (Illinois)|Regional Transportation Authority]] and CTA service connects with the commuter rail [[Metra]], and suburban bus and regional [[paratransit]] service, [[Pace (transit)|Pace]].

The Chicago Transit Authority provides service in Chicago and 10 surrounding suburbs.

The CTA operates 24 hours each day and on an average weekday provides over 950,000 rides on buses and trains. It has approximately 2,000 buses that operate over 127 routes traveling along {{convert|1,516|mi}}. Buses provide about 560,000 passenger trips a day and serve more than 10,000 posted bus stops. The Chicago Transit Authority's 1,560 train cars operate over eight routes and {{convert|226|mi|km}} of track. Its trains provide about 1,283,471 customer trips each weekday and serve 146 stations in Chicago and seven suburbs.<ref>{{Cite web |date=2025-05-15 |title=CTA Facts at a Glance - CTA |url=https://www.transitchicago.com/facts/ |access-date=2025-05-20 |archive-url=https://web.archive.org/web/20250515133926/https://www.transitchicago.com/facts/ |archive-date=May 15, 2025 }}</ref>

Currently, the CTA provides regular service within Chicago and the neighboring suburbs of [[Forest Park, Illinois|Forest Park]], [[Evanston, Illinois|Evanston]], [[Skokie, Illinois|Skokie]], [[Oak Park, Illinois|Oak Park]], [[Summit, Illinois|Summit]], [[Cicero, Illinois|Cicero]], [[Berwyn, Illinois|Berwyn]], [[North Riverside, Illinois|North Riverside]], [[Rosemont, Illinois|Rosemont]], [[Evergreen Park, Illinois|Evergreen Park]], [[Oak Lawn, Illinois|Oak Lawn]], [[Park Ridge, Illinois|Park Ridge]], [[Harwood Heights, Illinois|Harwood Heights]], [[Norridge, Illinois|Norridge]], [[Lincolnwood, Illinois|Lincolnwood]], and [[Wilmette, Illinois|Wilmette]].

The CTA accepts payment with a [[Ventra]] card, a Ventra disposable ticket, [[Contactless payment|contactless credit or debit card]], and certain smartphones. Unlimited ride Ventra cards/tickets are only valid for one passenger. CTA buses also accept cash. Up to three children under 7 can ride free with a fare-paying rider.

The CTA has many free and discounted fare options, for elementary, middle, and high school students, college and university students, people with disabilities, senior citizens, and military service members.

===Cash===
Only buses allow riders to pay directly with cash at a farebox. Exact fare is required, since no change is given. Since January 7, 2018, the bus full fare is $2.50, the senior/disabled fare is $1.25, and the student fare is $.75. No cash transfers are available. Previously, some rail station turnstiles accepted cash, but this feature has been removed in an effort to speed up boarding. Cash at rail stations is only accepted at Ventra Vending Machines to purchase Ventra cards and tickets.

===Transit Cards===
The CTA no longer sells Transit Cards. All remaining Transit Cards must have been used by July 1, 2014.<ref>{{cite press release|title=Transitioning to Ventra|url=http://www.transitchicago.com/transition/|publisher=Chicago Transit Authority|location=Chicago|access-date=June 14, 2014|archive-url=https://web.archive.org/web/20140620112639/http://www.transitchicago.com/transition/|archive-date=June 20, 2014|url-status=dead}}</ref> In its place CTA has adopted the Ventra Card system. The Ventra Card can be purchased online, Ventra Vending Machines at CTA rail stations, and at authorized retailers like Walgreens, CVS Pharmacies, and check cashing locations.

===Ventra===
{{Main|Ventra}}

Ventra is an electronic fare payment system for the Chicago Transit Authority and [[Pace (transit)|Pace]] that replaced the [[Chicago Card]] and the Transit Card automated fare collection system.  Ventra (purportedly Latin for "windy," though the actual Latin word is ''ventosa'')<ref>{{cite press release|last=Mancini Nichols|first=Chrissy|title=Talking Transit: Chicago transit gets open payment system|url=http://www.metroplanning.org/news-events/article/6548|publisher=Metropolitan Planning Council|location=Chicago|access-date=March 20, 2013}}</ref> launched in August 2013, with a full system transition slated for July 1, 2014.<ref>{{cite web|title=Ventra FAQ|url=https://www.ventrachicago.com/faq/|publisher=Chicago Transit Authority|location=Chicago|access-date=October 18, 2013}}</ref><ref name=JulyRollout>{{cite news|last=Thomas|first=Monifa|title=Ventra cards become only way to pay starting July 1|url=http://www.suntimes.com/26203756-418/ventra-cards-become-only-way-to-pay-starting-july-1.html|newspaper=Chicago Sun-Times|location=Chicago|publisher=Chicago Public Media|access-date=March 14, 2014|date=March 14, 2014}}</ref> The Ventra payment system includes several options of payment, including a [[contactless smart card]] powered by [[RFID]], a single day or use ticket powered by [[RFID]], any personal bank-issued credit card or debit card that has an [[RFID]] chip, and a compatible [[mobile phone]]. This includes Google Pay, Apple Pay, and Samsung Pay.<ref name=CTAVentra>{{cite web|title=Ventra|url=http://www.transitchicago.com/ventra/|publisher=Chicago Transit Authority|location=Chicago|access-date=October 18, 2013}}</ref> Ventra is operated by [[Cubic Transportation Systems]].<ref name=CTADebit>{{cite news|first=Jon |last=Hilkevitch |title=CTA's Ventra debit option rife with fees |date=March 20, 2013 |publisher=Tribune Publishing|location=Chicago|url=http://www.redeyechicago.com/news/ct-met-cta-ventra-hidden-fees-0320-20130320,0,3911415,full.story |archive-url=https://archive.today/20130411185138/http://www.redeyechicago.com/news/ct-met-cta-ventra-hidden-fees-0320-20130320,0,3911415,full.story |url-status=dead |archive-date=April 11, 2013 |work=Red Eye Chicago |access-date=March 20, 2013 }}</ref>

Riders using Ventra pay $2.25 for bus, $2.50 for rail (except Blue Line O'Hare station, $5). Disabled & seniors who are 65 or older pay $1.10 for bus, $1.25 for rail. Elementary and high school students  7–20 years old: Valid 5:30&nbsp;a.m. to 8:30&nbsp;p.m. on school days pay $.75 during school hours and pay $1.10 during weekends and holidays. The two transfers, within two hours, from the start of a trip is free. After that, it is considered a new trip and the user is charged another fare.

===Contactless payments===
Ventra readers on buses and rail station turnstiles can accept contactless payments directly from mobile devices. Riders can pay a PAYG fare ($2.50) by touching mobile phones with [[Apple Pay]], [[Google Wallet|Google Pay]] and [[Samsung Pay]]—or any contactless bankcard with the contactless wave symbol.<ref>{{cite web |title=How-To: Paying with Apple Pay, Android Pay or Samsung Pay |url=https://www.ventrachicago.com/how-to/mobile-wallet-apps/ |access-date=December 10, 2018 |publisher=Chicago Transit Authority |language=en}}</ref>

==Governance==
The CTA is governed by a seven-member board representing Chicago and the surrounding suburbs. Four members are appointed by the [[mayor of Chicago]], while the other three are appointed by the [[governor of Illinois]].<ref>{{Cite web |title=Chicago Transit Board (Info & Meetings) |url=https://www.transitchicago.com/board/ |access-date=November 18, 2025 |website=CTA |language=en}}</ref> The board is advised by the ADA Advisory Committee and Citizens Advisory Board, which are composed of Chicago-area residents chosen by the board.<ref>{{Cite web |title=ADA Advisory Committee |url=https://www.transitchicago.com/board/ada/ |access-date=November 18, 2025 |website=CTA |language=en}}</ref><ref>{{Cite web |title=Citizens Advisory Board (Info & Meetings) - Administration |url=https://www.transitchicago.com/about/citizens-advisory-board/ |access-date=November 18, 2025 |website=CTA |language=en}}</ref> Day-to-day operations are handled by Acting President [[Nora Leerhsen]].<ref name="President" />

==Fleet==
As mandated by the [[Americans with Disabilities Act of 1990]] for all transit operators in the U.S., all CTA buses are [[Accessibility|accessible]], with a ramp on every bus available for use upon request by anyone who has trouble with steps, even temporarily.  The majority of train stations CTA operates have elevators or ramps to provide access for customers with disabilities. All trains are accessible, either through fully level boarding or a ramp to bridge the 3-4in height gap.

===Bus fleet history===
[[File:19680609 41 CTA Rapid Transit @ Kenton Ave. (5629455595).jpg|thumb|L trains used to allow passengers to put arms out of window]]
[[File:Chicago Marmon 9728 on route 85-Central Ave, 1968.jpg|thumb|right|A [[Trolleybus|trolley bus]] serving route 85-Central in 1968]]

In 1953, the CTA placed an order for [[Flxible]] buses after the latter's absorption of the [[Fageol]] [[Twin Coach]] Company.

Until 1973, CTA's fleet included a large number of [[Trolleybus|electric trolley buses]]&nbsp;– or "trolley coaches", as they were commonly known at the time.<ref name="TrolleyCoachNA">[[Mac Sebree|Sebree, Mac]]; and Ward, Paul (1974). ''The Trolley Coach in  North America'', pp. 49–60. Los Angeles: [[Interurban Press|Interurbans]]. LCCN 74-20367.</ref> In the 1950s, the fleet of around 700 trolley coaches was the largest such fleet in the U.S., and represented about one-quarter of CTA's total number of surface-transit vehicles (motor bus, trolley bus and, until 1958, [[streetcar]]). Possibly influenced by the [[1967 Chicago blizzard]], during which CTA trolley buses were unable to maneuver around abandoned automobiles without dewiring, CTA decided to discontinue trolley bus service. Trolley bus service was phased out in the late 1960s and early 1970s, and trolley buses ran for the last time on March 25, 1973.<ref name="TrolleyCoachNA"/><ref name="Murray">Murray, Alan (2000). ''World Trolleybus Encyclopaedia'', p. 79. Yateley, Hampshire, UK: Trolleybooks. {{ISBN|0-904235-18-1}}.</ref>

CTA buses were known as the "green limousine" or the "big green" &mdash; buses were one or more shades of green from the CTA's establishment until the end of the 1980s. With the delivery of the [[Transportation Manufacturing Corporation|TMC]] [[Rapid Transit Series|RTS]] buses in 1991, a more patriotic color scheme was adopted, and the green scheme was fully phased out by 1996. A notable color scheme was the "[[United States Bicentennial|Bicentennial]]" of about 1974 to 1976.<ref>{{Cite web|url=http://busdrawings.com/Transit/illinois/chicago/1974t8h5307a/7903.jpg|title=Harry Gershen photograph at busdrawings.com}}</ref>

CTA bought very few buses between the mid-1970s and the end of the 1980s. During this time, purchases were only made in 1979 (20 [[MAN SE|MAN]]/[[AM General]] [[MAN SG 220|SG 220]] [[articulated bus]]es), 1982-83 (200 [[New Flyer Industries|Flyer]] [[Flyer 700/800/900 series|D901]] buses and 125 additional MAN articulateds), and 1985 (362 MAN Americana standard-length buses). Another aspect of this period was that with the exception of the 1979 and 1983 MAN orders, none of those buses had air-conditioning, a budget saving move by the CTA. The 1972-76 fleet of [[GM New Look bus|GM "New Look" buses]], 1870 total, which were originally air-conditioned (although there were problems with the air-conditioning systems, eventually being disabled and sliding windows installed in the buses), composed the majority of vehicles in service into the early 1990s.

In 1995, the CTA placed an experimental order of their first 65 low floor transit buses from [[New Flyer Industries]] [[New Flyer Low Floor|D40LF]]. Also, that same year, the CTA received its last order of high floor buses from Flxible Corporation, shortly before the manufacturer folded.  In 1998, the CTA placed an order for 484 new low floor transit buses from [[Canada|Canadian]] bus-building firm [[Nova Bus]]. This executed move billed the CTA as Nova's American launch customer for the latter's signature product, the LFS series. This was also done to meet the "Buy American" requirements for buses in the United States transit bus market, since [[General Motors]] ceased bus production and Flxible went out of business. Lastly, these buses replaced the ones that were built in 1983 and 1985 as these buses both lack air conditioning, aging, and not ADA compliant.

Today CTA's current fleet of buses is mostly dominated by New Flyer's [[New Flyer Low Floor|D40LF]], numbered 1000–2029, which replaced buses that were built in 1991 and 1995. In 2014, CTA ordered 400 new buses from [[Nova Bus LF Series|Nova]]. The number increased to 425 after it exercised an option. The buses are numbered 7900–8324. The CTA exercised another option for an additional twenty-five buses, numbered 8325–8349, from Nova Bus. Nova Bus delivered an additional 600 new buses (numbered 8350–8949) which replaced the remainder of the older Nova buses that were delivered between 2000 and 2002, in addition to starting the retirement of New Flyer [[New Flyer Low Floor|D40LF]] buses delivered between 2006 and 2009.{{Citation needed|date=October 2025}}

After the [[September 11 attacks]], CTA announced its "If you See Something, Say Something" campaign.<ref>{{cite web|url=http://www.transitchicago.com/safety/default.aspx|title=CTA Security & Safety|publisher=CTA}}</ref> CTA has also installed a security camera network,<ref>{{cite press release|url=http://www.transitchicago.com/news/default.aspx?&ArticleId=562

CTA has also been actively prosecuting vandals, announcing on several occasions that felony convictions were obtained against persons who spray painted authority vehicles.<ref>{{cite press release|url=http://www.yourcta.com/news/ctaandpress.wu?action=displayarticledetail&articleid=119081|publisher=CTA|date=March 21, 2008|title=Vandal Sentenced to Prison for Defacing CTA Property}}{{dead link|date=August 2017 |bot=InternetArchiveBot |fix-attempted=yes }}<br />{{cite press release|url=http://transitchicago.com/news/ctaandpress.wu?action=displayarticledetail&articleid=130753|publisher=CTA|date=December 19, 2007|title=CTA Vandal Receives Felony Conviction for Criminal Defacement and Trespass}}{{dead link|date=August 2017 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

==Technology==
The CTA installed GPS Bus Tracker systems on all buses starting with the 20 (Madison St) bus in 2006,<ref>{{cite web|url=https://www.transitchicago.com/mayor-daley-cta-launch-bus-tracking-pilot/|title=Mayor Daley, CTA Launch Bus Tracking Pilot|website=CTA|access-date=February 4, 2019}}</ref> before expanding it to other routes in 2008.<ref>{{cite web|url=https://www.transitchicago.com/cta-expands-bus-tracker-program/|title=CTA Expands Bus Tracker Program|website=CTA|access-date=February 4, 2019}}</ref> The original claim justifying the addition of this technology was that it would reduce the issue of [[Bus bunching|bunching buses]]. The system also allows riders to be able to determine the location of buses online.

A report prepared by the CTA claims that there was a decrease in bus bunching from 3.9% to 2.3% from 2007 to 2009, but the report neither demonstrated a direct connection between Bus Tracker and this reduction in bunching, nor did it show whether this was a temporary or permanent phenomenon.<ref>{{cite web|url=http://www.chicagocurrent.com/articles/30889-Bus-bunching-down-40-since-2007-CTA-report-says|title=Bus bunching down 40% since 2007, CTA report says|author=Ben Meyerson|publisher=Chicago Current|date=December 16, 2009|access-date=December 17, 2009|archive-date=May 25, 2011|archive-url=https://web.archive.org/web/20110525202626/http://www.chicagocurrent.com/articles/30889-Bus-bunching-down-40-since-2007-CTA-report-says|url-status=dead}}</ref>

==Special events==

=== Holiday Train ===
During the months of November and December, the CTA decorates several "L" rail cars in seasonal decorations and lights, which run alongside an open-air flatcar transformed into [[Santa Claus|Santa]]'s sleigh as the [[CTA Holiday Train]].

=== Heritage fleet ===
The CTA maintains a small fleet of former rolling stock and buses for use during special events and for private charters.<ref>{{Cite web |title=Commuters Step Back in Time as CTA Brings Out 1970s Railcars for Crosstown Classic Game |url=https://news.wttw.com/2025/05/16/commuters-step-back-time-cta-brings-out-1970s-railcars-crosstown-classic-game |access-date=2025-09-29 |website=WTTW News}}</ref> These include [[4000 series (Chicago 'L')|4000-series]] rail cars, [[6000-series (CTA)|6000-series]] rail cars, [[2400-series (CTA)|2400-series]] rail cars, and buses built by [[GMC (automobile)|GMC]] and [[Flxible]].<ref>{{Cite web |title=CTA Heritage Fleet (Historical Trains & Buses) |url=https://www.transitchicago.com/heritagefleet/ |access-date=2025-09-29 |website=CTA |language=en}}</ref>

=== Pride Train ===
Since 2017, the CTA has run a specially-wrapped train during [[Pride Month]], making it the first transit agency in the United States to do so.<ref>{{Cite web |title=CTA Unveils New Pride Train Design in Celebration of LGBTQ+ Pride Month |url=https://news.wttw.com/2025/06/02/cta-unveils-new-pride-train-design-celebration-lgbtq-pride-month |access-date=2025-09-29 |website=WTTW News}}</ref>

== Public art ==
The CTA is home to a collection of art – including mosaics, sculptures and paintings. More than 50 pieces of art are exhibited at over 40 CTA stations.<ref>{{cite web |title=Online Gallery - Public Art on CTA |url=http://www.transitchicago.com/art |publisher=CTA}}</ref>

According to the CTA, the original pieces of artwork contribute to each station's identity and enhance travel for customers.{{citation needed|date=December 2024}} Many of the pieces are a result of the Arts in Transit Program, which is funded by the Federal Transit Administration and coordinated locally through the City of Chicago's Office of Tourism and Culture. A number of other pieces were created through the CTA's Adopt-A-Station program and through partnerships with organizations such as the [[Chicago Public Art Group]].<ref>{{cite web |title=Public Art on CTA - video |url=https://www.youtube.com/watch?v=sGyCzlkI_xw |publisher=CTA}}</ref>

=== Arts in Transit ===
In 2004, the CTA and the City of Chicago Public Art Program installed nine permanent works of art at eight renovated rail stations on what is now known as the Pink Line. The CTA has since created an ongoing program to showcase permanent works of art in conjunction with the City of Chicago Public Art Program. The Arts in Transit Program is funded by the Federal Transit Administration, and created opportunities to develop original artwork for station reconstruction projects along the CTA Red and Brown Lines. Artists were selected for each of the stations included in the Brown Line Capacity Expansion Project and select renovated Red Line stations.

With the completion of the Brown Line Capacity Expansion Project in December 2009, original artwork was installed in each of the 18 renovated stations along the CTA's Brown Line. By combining the visibility and accessibility of the city's mass transit system with the creativity of Chicago's art resources, this program resulted in a successful public display of professional works of art designed with input from nearby communities. This program provided high-profile locations for public art and server as a gateway to communities served by the CTA stations. Media under consideration included, but were not limited to, mosaics, art glass, ornamental fencing, mixed-media artwork, and freestanding sculpture and furniture.

The CTA and the City of Chicago Public Art Program, administered by the Office of Tourism and Culture, encouraged and facilitated collaborations between artists, government agencies, the community and other partners. The City of Chicago Public Art Program accepted qualifications from local and national professional artists or artist teams capable of creating permanent public works of art for the CTA Arts in Transit Program for the renovated stations.{{Citation needed|date=June 2020}}
