A Ticket to Tomahawk (1950)

In 1876, Dawson wants to prevent a train from getting to Tomahawk, Colorado on time, to keep it from competing with his stagecoach line. Kit, who must get the train to its goal, forces Johnny aboard as the needed passenger. Madame Adelaide's showgirls (including Marilyn as Clara) ride along and, en route to Tomahawk, join Johnny in "Oh, What a Forward Young Man You Are".
