Just saw "Going Home," from 1971. Robert Mitchum, Brenda Vaccaro, Jan-Michael Vincent. There's a minute or two of the latter in what I guess is Pittsburgh - looks like trackage neighboring steel mills. Lots of PRR hoppers with coal or coke, empty P&LE gondolas, green P&LE box cars. A couple P&LE SW switchers - 8957 and 8958 - Vincent appears to be riding on one of them, with what looks to be a U Boat leading a moving train two tracks over on the right, in the background. Then he drops off, waves to the crew, and cuts across the tracks.
