Library is a station on the Port Authority of Allegheny County's light rail network, located in the Library neighborhood of South Park, Pennsylvania. It is the southern terminus of the Library branch of the Blue Line. A 430 space park and ride lot is located on the premises, drawing travelers from both South Park and Pittsburgh's suburbs in Washington County, located just to the south. Despite the station's name there is no lending library near the train station, in the past many riders have been confused into thinking there was an actual library there.
The Pittsburgh Railwaysinterurban line from Charleroi to Pittsburgh was opened through South Park on September 12, 1903, with passengers changing at Castle Shannon to continue their journey to Downtown via the Pittsburgh and Castle Shannon Railroad. It was cut back to Library in 1953, with a turnaround loop for the single-ended PCC's that operated on the line. In the late 1980s, new light rail vehicles began to use the line. These new cars had larger, articulated bodies, and were thus unable to negotiate the loop. Moreover, these cars were double-ended, eliminating the need for such turn-around facilities. In 2004, the loop was removed and a new, larger station was built to better accommodate the light rail cars.
