Decision At Sundown Iron Horse : Season 1 Episode 25

With Calhoun away, the train is taken over by a group of ruthless outlaws who demand that Dave turn over a large fortune in bonds that is being delivered. Dave tells them that they will have to wait for Calhoun to return with them, but that is a delaying tactic as Calhoun will not be back that soon and Dave may have to resort to other plans to save the lives of the crew and passengers.
