A Train of Incidents (1914)

Two young people, Betty Browne and Billy, are set to inherit money if they marry, but each imagines the other as a rough cowboy and refuses; by chance, they end up on the same train with their chaperones (Miss Prim and Bunny), leading to mistaken identities, romantic confusion (as Bunny and Miss Prim fall for each other too!), and a hilarious mix-up before they finally discover each other's true identities at a station and fall in love for real.
