Night Passage (1957)

The workers on the railroad haven't been paid in several months. That's because Whitey and his gang - including fast-shooting, dangerous, but likeable Utica Kid - keep holding up the train for its payroll. Grant McLaine, a former railroad employee who was fired in disgrace, is recruited to secretly take the payroll through. A young boy and a shoe box figure into the plot when Whitey's gang tries to hold up the train, and Grant and the Kid meet again to settle an old score.
