Featuring Pittsburgh Railways

Pittsburgh Railways started in 1902 with the acquisition of several local traction companies. In 1905 Pittsburgh Railways leased the Pittsburgh & Castle Shannon Railroad which operated on a line built by the railroad in 1871 called the Overbrook Line from Pittsburgh to Castle Shannon. In 1964 the Port Authority of Allegheny County more commonly known as PAT acquired Pittsburgh Railways.

At one time Pittsburgh Railways had 600 miles of track and a fleet of 668 PCC cars third largest in North America behind Chicago and Toronto, with their 683 and 745 cars, respectively. The once 600 miles of track has now been reduced to 25 miles.
