The Pennsylvania Railroad. The rayish-brown terra cotta building is Pittsburgh's Union Station, designed by architect Daniel Burnham, and was constructed from 1898 to 1904. It served as a key stop for both east and west trains of the Pennsylvania Railroad until the early 1970s. Following its purchase by the US General Services Administration from the Penn Central Corporation in the late 1970s, a $20 million restoration project was initiated in 1986. This aimed to convert the office tower into apartments. While the building remains an active railway station, trains now utilize an annex on the Liberty Avenue side. The Amtrak station is the final stop for the Pennsylvanian train from New York to Pittsburgh and is also a crew change point for the Capitol Limited, traveling between Chicago and Washington, D.C.
