Union Station [from a story by Thomas Walsh] is a melodrama that locales its thrills in a big city railway terminal and spins off a tale of kidnapping.
William Holden, while youthful in appearance to head up the railway policing department of a metropolitan terminal, is in good form. Kidnapping is revealed when a femme passenger arriving at the terminal reports two suspicious characters. The passenger is Nancy Olson, secretary to a rich man and his blind daughter (Allene Roberts). Events prove Roberts has been kidnapped and the terminal is to be used as the payoff location.
The production catches the feel of a large terminal and its constantly shifting scenes of people arriving and departing.
