Map of the "T" light rail system.

The Pittsburgh Light Rail (commonly known as The T) is a 26.2-mile (42.2 km)[1][4] light rail system in Pittsburgh, Pennsylvania; it functions as a subway in Downtown Pittsburgh and largely as an at-grade light rail service in the suburbs south of the city. The system is largely linear in a north-south direction, with one terminus just north of Pittsburgh's central business district and two termini in the South Hills. The system is owned and operated by the Port Authority of Allegheny County. It is the successor system to the streetcar network formerly operated by Pittsburgh Railways, the oldest portions of which date to 1903.[5] The Pittsburgh light rail lines are vestigial from the city's streetcar days, and is one of only three light rail systems in the United States that continues to use Pennsylvania Trolley (broad) gauge rail on its lines instead of standard gauge. Pittsburgh is one of the few North American cities that have continued to operate light rail systems in an uninterrupted evolution from the first-generation streetcar era, along with Boston, Cleveland, New Orleans, Newark, Philadelphia, San Francisco and Toronto.



In the early 1960s, Pittsburgh had the largest surviving streetcar system in the United States, with the privately owned Pittsburgh Railways Company operating more than 600 PCC cars on 41 routes. In 1964 the system was acquired by the Port Authority of Allegheny County (PAT), which rapidly converted most routes to buses. By the early 1970s, only a handful of streetcar routes remained, most of which used the Mt. Washington Transit Tunnel just south of the Monongahela River to reach the South Hills area.

At that time, Port Authority planners were determined to scrap the rail system entirely in favor of busways (now called "BRT" for "Bus Rapid Transit") and an automated guideway transit system developed by Westinghouse Electric called Skybus. Community opposition rallied against the plan and in favor of retaining the electric rail trolley system and upgrading it into modern LRT. In the end, the LRT option was adopted for the South Hills suburbs, along with development of a busway ("BRT") system for the eastern and western suburbs.

Subway tunnels

The modern subway in downtown Pittsburgh between Steel Plaza and First Avenue stations uses the Pittsburgh & Steubenville Extension Railroad Tunnel, which began construction in 1863.[6] Rail lines (trolleys) had been a staple of the city and region since the late 19th century, the idea of a downtown to Oakland or East Liberty subway had been considered since at least the 1910s. A public referendum was passed to fund such a subway with an initial investment of $6 million on July 8, 1919, another $5.5 million subway plan was finalized at City Hall in meetings on March 28, 1932, and the public/private Allegheny Conference presented detailed plans and funding for a subway system on June 4, 1947.

Pittsburgh Railways

Pittsburgh Railways was one of the predecessors to the Port Authority of Allegheny County (PAT). It had 666 PCC cars, the third largest fleet in North America. It had 68 street car routes, of which only three (until April 5, 2010 the 42 series, the 47 series, and 52) are used by the Port Authority as light rail routes. The oldest portions of these old Pittsburgh Railways routes now served by the Pittsburgh Light Rail system date to 1903-1909.[5] With the Port Authority's Transit Development Plan, many route names will be changed to its original, such as the 41D Brookline becoming the 39 Brookline. Many of the streetcar routes have been remembered in the route names of many Port Authority buses (e.g. 71 series).

1895 to 1905 was a time of consolidation for the numerous street railways serving Pittsburgh. On July 24, 1895 the Consolidated Traction Company was chartered and the following year acquired the Central Traction Company, Citizens Traction Company, Duquesne Traction Company and Pittsburgh Traction Company and converted them to electric operation.[7] On 27 July 1896 the United Traction Company was chartered and absorbed the Second Avenue Traction Company, which had been running electric cars since 1890.[8]

The Southern Traction Company acquired the lease of the West End Traction Company on October 1, 1900. Pittsburgh Railways was formed on January 1, 1902, when the Southern Traction Company acquired operating rights over the Consolidated Traction Company and United Traction Company.[9] The new company operated 1,100 trolleys on 400 miles (640 km) of track, with 178.7 million passengers and revenues of $6.7 million on the year.[10]

Unfortunately the lease and operate business model proved hard to support and the company declared bankruptcy twice, first in 1918 lasting for 6 years and then again in 1938, this time lasting until January 1, 1951.[11]

On 26 July 1936 Pittsburgh Railways took delivery of PCC streetcar No. 100 from the St. Louis Car Company. It was placed in revenue service in August 1936, the first revenue earning PCC in the world.[12][13]

Large scale abandonments of lines began in the late 1950s, usually associated with highway or bridge work.[14]

1960s and Skybus '70s

In the 1960s a 92-mile (148 km) automated guideway transit system was planned fanning out to the north, south, east, southeast and west including connections to both the Pittsburgh International Airport the Allegheny County Airport, Monroeville Mall and adjacent to Kennywood Amusement Park. The modern subway/light rail system can be traced to the abandonment of the proposed "Skybus" system in the mid-1970s, and the subsequent $265 million federal grant on May 7, 1979, for construction of a downtown subway and modernization of suburban light rail.

Modern system

PAT, working with community representatives and government officials, undertook a detailed study on the future of the South Hills trolley lines, resolving to transform these valuable, high-density transit corridors into a modern LRT system. The resulting Stage I LRT plan achieved a comprehensive reconstruction and upgrading of the 10.5-mile (16.9 km) "main line" between downtown and the suburbs of Bethel Park and Upper St. Clair via Mount Lebanon and Beechview—basically following the Skybus alignment. The crowning achievement was to be a 1.1-mile (1.8 km) downtown subway, eliminating the trolleys' slow, street-running loop through Pittsburgh's Golden Triangle.

On December 10, 1980, after receiving federal funding, the Port Authority began construction on Stage One of its first "modern" light rail/subway service, the "T", which used a former Pittsburgh Railways trolley route to connect Downtown Pittsburgh to the South Hills. Stage One began with two construction projects – the downtown subway, and the former trolley route from the newly constructed South Hills Village Station and Light Rail Maintenance Center to Castle Shannon – both ends working toward the middle section of the route.

Steel Plaza subway station, the most utilized station on the system.

The first modern light rail cars began operation from South Hills Village to Castle Shannon on April 15, 1984[15] with the downtown subway added to the system on July 3, 1985. The last leg of the modern suburban "Beechview" line (from Castle Shannon to South Hills Junction via Mt. Lebanon and Beechview) was approved for funding May 8, 1985 with $20 million in federal grants and completed the modern system on May 22, 1987 at a total cost of $522 million. The suburban line in the south hills were former streetcar lines that had been rehabilitated to accommodate light rail vehicles. The Beechview line was reconstructed (being completely double tracked) and routed from the South Hills Junction through the Mount Washington Transit Tunnel, emerging at a newly constructed station at Station Square before crossing the Monongahela river on the Panhandle Bridge (a former railway bridge), which then led into a newly built downtown (cut and cover tunnel) subway with four stations, which incorporated the nineteenth century Pittsburgh & Steubenville Extension Railroad Tunnel. The downtown subway had four stations, Steel Plaza, Wood Street, Gateway Center, and Penn Station. The original subway branched north of Steel Plaza, with one branch heading west to Wood Street and one branch heading east to Penn Station.

The transformation was remarkable. An outdated, suburban trolley line with conventional jointed rail, aging electrical overhead and single track segments was reborn as a wholly double track light rail line with continuous welded rail and modern catenary. Upon completion of the subway, all former streetcar lines were removed from the surface streets of Downtown Pittsburgh.

Overbrook Line reconstruction

The line from South Hills Junction to Castle Shannon via Overbrook (now called the Overbrook Line) was first constructed by the Pittsburgh and Castle Shannon Railroad (P&CSRR) between 1872 and 1874.[16] In 1905, Pittsburgh Railways leased the route, and between 1909 and 1910, converted it to dual gauge, retaining the existing narrow gauge for the coal hauling trains and adding the Pennsylvania 5' 2-1/2" broad gauge for passenger service using streetcars. While the line was electrified with overhead power, the coal trains continued to use existing steam locomotives.

While the Beechview line was rebuilt during the 1980s, the Overbrook line remained largely unchanged and continued to be operated using PCC cars. The reconstruction of this line would be part of the Stage II project, to be performed at a future date pending additional funding. However, the condition of the track and infrastructure of the Overbrook line continued to deteriorate and in 1993, Port Authority determined the line to be unsuitable for safe operation in its current state and suspended service on the line. The line remained dormant until 1999, when Port Authority broke ground on the Overbrook Line reconstruction project.

The rebuilt Overbrook line was essentially an entirely new line built along the original line's right of way. As had been done with the Beechview line prior, the rebuilt line was completely double-tracked with continuously welded rail, pandrol clip fixation, upgraded catenary and signaling, and other improvements. The line as rebuilt featured eight high-level platform ADA accessible stations and, unlike the Beechview line, did not retain any street-level stops. The Overbrook line reopened in June, 2004. Coinciding with the opening, Port Authority purchased 28 additional light rail cars to support the line and increase overall system capacity. At this time, the 55 existing cars were completely rehabilitated as well. Ironically there is no station in the Overbrook neighborhood since the rail line is built into a hillside where construction of an ADA accessible station would involve considerable complexity.

In addition, as part of the Stage II project, upgrades to the traction power network, Operations Control Center, and signals and communications had been implemented.

North Shore Connector

The finished North Shore Connector includes Allegheny station, serving the Heinz Field and Carnegie Science Center. Notice the Pittsburgh Steelers banner prominently displayed. The red car sports an advertising wrap in the style of Pittsburgh Railways Co coloring and the PAAC 50th Anniversary logo.

In January 1999, the Port Authority of Allegheny County began undertaking environmental analysis, planning, and began construction of a light rail line to connect Pittsburgh's Downtown and North Shore. Federal funding was approved for the extension on February 6, 2004.

The main project involved twin bored tunnels below the Allegheny River to connect a refurbished Gateway Station, which is the current Downtown terminus, to North Side station, located just west of PNC Park and Allegheny station, located just north of Heinz Field. The completed project opened to the public on March 25, 2012. The North Side station serves PNC Park, the Andy Warhol Museum, Allegheny Center and numerous office buildings in the vicinity. The Allegheny station serves Heinz Field, the Carnegie Science Center, the National Aviary, the Community College of Allegheny County, the Rivers Casino, and other nearby businesses.

Unexpectedly high bids from construction companies had stalled construction, originally scheduled to begin in Fall 2005. The entire project is budgeted at $435 million, with approximately 80% ($348 million) coming from the Federal Transit Administration.[17] The Port Authority began construction in October 2006, with the first bore completed on July 10, 2008 and the second tunnel under the Allegheny river completed in early 2009.[18] Service began on March 25, 2012 with a final cost of $523.4 million.[19]

Fleet and depot

Current fleet

Port Authority operates a fleet of 83 LRVs as of 2006:

Trains are generally run in a two car configuration. The routes have sections that have a dedicated right of way as well as mixed sections that run along roadways with automobile traffic. Generally, stations along roadways have low level platforms while stops along the dedicated rights of way have high level platforms. To allow easy boarding in both situations, the trains have two sets of doors at the front, with a low set and a staircase as well as a high set with level access from the platform to the train.

Retired PCC fleet

The four remaining PCC cars were retired in 1999. These PCCs were from an original fleet of 12 "homebuilt" cars constructed in the 1980s in the Port Authority shops using a combination of new underframes, lower body panels, front and rear ends, interiors, wiring and controls, together with reconditioned components such as trucks, motors, and upper body parts and windows reused from original Pittsburgh PCCs numbered in the 1700 series. They avoided the breakers yard, along with some other trolleys from the later years of PAT ownership.

The South Hills Village Rail Center (SHVRC) is located at the end of the Blue Line - South Hills Village, adjacent to the shopping mall of the same name. All of the revenue light rail vehicles (LRVs) and some Maintenance of Way vehicles are stored there. All the old PCC cars were stored there as well prior to their retirement in 1999.


The "T" has three active lines along with several discontinued lines.

Red Line

Formerly 42S. The Red Line runs between South Hills Village and Downtown Pittsburgh via the Beechview neighborhood. Six stops serve Upper St. Clair and Bethel Park before merging with the Blue Line at Washington Junction. The Red Line splits again before Overbrook Junction (PAT station) and the Red Line heads toward the suburbs of Castle Shannon, Mt. Lebanon, and Dormont. After entering Pittsburgh city limits, the route features a variety of closely spaced stops through Beechview, where bus service is limited due to the hilly terrain, despite a dense population. Twenty stops occur between the split in the lines and their re-juncture at South Hills Junction. The route then enters the Mt. Washington Transit Tunnel. The remaining stations in Downtown are at Station Square, First Avenue, Steel Plaza, and Wood Street (PAT station). In March 2007, the closure of the Palm Garden Bridge for refurbishment suspended the 42S for five months; it re-opened in September 2007.[20][21]

Blue Line – Library

Formerly 44L, 47L. Service begins near the Allegheny County line in the Library neighborhood of South Park. Fifteen stops serve Library, Bethel Park, and South Park before merging with the Blue Line - South Hills Village line at Washington Junction. Some weekday, and all weekend trips end at Washington Junction, where a timed transfer to the Blue Line - South Hills Village will continue a trip to Overbrook and Downtown. For the trips that serve Downtown, the line splits again before Overbrook Junction station on the Red Line, as the Blue Line instead follows the Overbrook route. The line then makes eight well-spaced stops on its arc through the Overbrook, Brookline, Carrick, Beltzhoover, and Bon Air neighborhoods of southern Pittsburgh. The line merges with the Red Line at South Hills Junction before entering the Mt. Washington Transit Tunnel. The remaining stations are at Station Square, First Avenue, Steel Plaza, and Wood Street.

Blue Line – South Hills Village

Formerly 47S. In 2005, the Port Authority opened a new parking garage at the South Hills Village station. The 47S line was established in an effort to relieve congestion on the Red Line for the additional traffic that the parking garage created. The Blue Line - South Hills Village route follows the South Hills Village leg of the Red Line and the common leg from Washington Junction to Willow Station, which is adjacent to Overbrook Junction, where it switches to the Blue Line - Library mainline. It follows the Blue Line - Library to South Hills Junction where it reunites with the Red Line before entering downtown.

Discontinued lines

47D Drake

When light rail service began, PCC trolley service continued from Drake north through Castle Shannon along the Overbrook line to downtown. All downtown platforms incorporated both low- and high-level platforms enabling them to handle both types of vehicles. When safety concerns prompted the closure of the Overbrook line in 1993 the Drake line was cut back to Castle Shannon; service would later terminate at Washington Junction. In September 1999, PAT withdrew the four remaining active-service PCCs from service and closed the Drake line altogether.[22]

47 Shannon

This was a PCC trolley line that led commuters either northbound (via Overbrook line) or southbound (via South Hills Junction, Drake or Library lines) to Castle Shannon station. The line's turnaround point, the Shannon Loop, was located just past the station at Mt. Lebanon Blvd. This loop no longer exists. Also removed from the Shannon route were the tracks surrounding the old Castle Shannon Municipal Building (which is also gone) at the intersection of Castle Shannon Blvd. and Willow Ave. At this Overbrook line connector, incoming trolleys ran in front of the building and outgoing trolleys ran behind the building and through the narrow passage between the building and Castle Shannon Blvd.

Brown Line

Formerly 52. The Brown Line ran from South Hills Junction low platform (except the first and last trips of each rush, which serve the high platform) over Mount Washington and across the Monongahela River to downtown Pittsburgh, terminating at Wood Street. It is the only downtown route that does not stop at Station Square nor use the Mount Washington tunnel. The line supplements the 46K bus, running 4 times each during the morning rush and 3 times during the evening rush. A throwback to the days of the streetcars, the 52 does not feature stations or street-level boarding stops (which are generally designed like bus shelters in the suburbs, or are concrete island platforms in Beechview) but instead allows for boarding and unloading at designated 46K bus stops. Two inbound and two outbound trips (the first one in and the last one out of each rush) serve South Hills Village via the Blue Line. This service exists because the train is coming from the rail center located near South Hills Village Mall, and serves the entire length of the route. The steepest grade on the entire light rail system is on this line, about 10 percent.[18]

This service was discontinued in the March 27, 2011 system-wide cuts.

The line is still in existence, and is used as a bypass to the Mount Washington Tunnel during maintenance. The tunnel is closed to all vehicular (bus) and light rail traffic during maintenance.

44L and 44S

The 44 Castle Shannon-Library (44L) and the 44 Castle Shannon-Beechview (44S) were truncated versions of the Blue Line - Library and Red Line, respectively. The 44L ran from Library to Washington Junction. The 44S ran between Overbrook Junction and Traymore. It was introduced when the closure of the Palm Garden Bridge cut off the Beechview line from the Downtown. The 44S was discontinued when the Palm Garden Bridge re-opened, in favor of the 42C.[21]


Extensions and additions

Since November 1993 the Authority has studied the so-called "Spine Line" [23] to the Oakland neighborhood which is the third largest center for commuters in the commonwealth and the home to Carlow University, the University of Pittsburgh, Carnegie Mellon University, the Pittsburgh Technology Center, the University of Pittsburgh Medical Center and Phipps Conservatory. Thus far the extension to Oakland has not gone beyond the design phase. The First Avenue station was added in 2001;[citation needed] service to Penn Station was suspended on September 2, 2007.[citation needed] The "T" is most heavily used in four stations downtown (three of which are underground), where service is free of charge.

Proposed extensions

Former Chief Executive of Allegheny County, Dan Onorato, hoped to eventually extend the light-rail system east to Oakland[24] and west to Pittsburgh International Airport.[25] In 2009, Onorato along with Congressman Mike Doyle requested approximately $7 million in funding from the federal government for preliminary planning of the extension.[26]

The Pittsburgh Post-Gazette has taken a strong editorial stance in late 2012 for a workable extension to the Northern suburbs all the way to Cranberry.[27]

Several conceptual designs of comprehensive light-rail systems have been created for Pittsburgh in recent years. These designs include Ben Samson's Transit Map and Extracogent's Pittsburgh Metro Map.
