Kirk's got it! The picture was taken from the back of a commuter train heading North into the Mount Royal train tunnel. The camera was a Pentax K1000 with the standard 50mm lens, and the film was Kodak TMAX p3200.
The train was a real museum piece on rails. I believe it was built during the nineteen-thirties, and was kept running well in the nineties. The picture itself was taken in 1991. I'll get myself a new scanner and locate the pictures I have of the train itself. It's quite a sight to behold.
What was funny was the n00b next to me who kept saying "your picture won't be any good."
