Dunno about search engines, but according to IMDB, the station scenes were filmed at Pathe Studios, Hollywood- presumably a sound stage set.
I didn't watch the whole clip in detail (and I've probably seen the movie on TV at some point), but from the trainboards it looks to replicate LaSalle Street Station in Chicago (NYC trains). Only one short clip at 6:11 (and possibly another) MIGHT show LaSalle St., as a rear projection. A look at a 1953 Official Guide (the oldest I have handy) shows that some train numbers match; 20th Century, Motor City, Ohio State...
(A movie related aside; LaSalle St.- the real one- was also used in "North by Northwest", and "The Sting".)
