Well, this was on TCM last night and this morning, on Noir Alley - "The Killer That Stalked New York." Most of the real train bits are at the beginning - one of the stars arrives on a train at Penn Station - GG1 No. 4919, now at the Virginia Museum of Transportation, leading. There are some shots of what appears to me to be Penn Station (movie is from 1950, though maybe shot a year earlier), but I never saw the real thing - or if I did, I was too young to remember.
When she climbs up stairs after alighting from the train, the post at the bottom of the stairs matches that of the pic in the Remnants of Penn Station Tour thread in Real Trains. Except there is more - the ball on top of the post that's missing now, and the ironwork on the post that's either gone or painted over currently.
For people who know the station and can comment - she passes out of the gate, in the background is a Travelers Aid Station sign atop a structure. Across the hall are pay phones - above them a sign that says Public Telephone/Attended Service. In the middle of a hall is a newsstand. She walks out with a Red Cap - across the street is the Hotel Statler (Hotel Pennsylvania).
There's a few shots later on of what I think is from a platform on the 3rd Avenue El - but I could be wrong.
