The Major and the Minor (1942)

Returning to her hometown from New York, Susan Applegate learns that she hasn't enough for the train fare and disguises herself as a twelve-year-old to travel for half the price. She hides from the conductors in the compartment of Major Philip Kirby, a military school instructor, who takes the "child" under his wing.
