Pittsburgh is really, really bad. True, it's not much of a "destination" on Amtrak; only two long-distance routes (Capitol Limited and the Pennsylvanian) stop here, and each runs only daily. And the CL arrives and leaves in the wee hours because Pittsburgh is the halfway point between Washington and Chicago. But even so, connections to local transit are poor. Several bus routes stop within a few blocks, but you won't find map or schedule information at the station. And there isn't even a safe pedestrian route. The only sidewalk is narrow, cobbled, and impossible for anyone with rolling luggage, and we won't even mention a wheelchair. Sure, you could cross to the opposite side (by the Greyhound terminal). But in a nice touch, that involves crossing four busy lanes of traffic. Without a signal or even a painted crosswalk.
What makes this particularly heartbreaking is that Pittsburgh's station is just an Amshack, though adjacent to the wonderful Union Station designed by Daniel Burnham at the turn of the last century with its beautiful rotunda. Its location is excellent, and Pittsburgh should be a natural hub for long-distance, regional, and commuter rail; but it isn't.
