SEPTA (former Red Arrow Lines) west of Philadelphia
This is a preserved North Shore Line car operating at the East Troy Museum. Perhaps this is one of the cars on which my father actually worked.
This is the last run of the Milwaukee Road Cannonball commuter train out of Milwaukee; the picture was taken at Brookfield.
One aspect of railroading which I think is fascinating are the stations, a lasting tribute to a bygone era. When I would visit a city for the first time, I would typically find and photograph the train station, some no longer in use. I have included several from across the country which are clearly identifiable, and which show three completely different approaches to station building. Here is Los Angeles Union Passenger Terminal.
From the Midwest this is Milwaukee Union Station.
From the East this is the Pennsylvania Railroad's 30th Street Station in Philadelphia. It looks more like a courthouse or large bank than a train depot, and it is clear what image the PRR wanted to project with this building.
