Tom and Jerry somehow acquire a locomotive, which is happily steaming over hills and mountains until it runs out of gas. A saint Bernard shows up with a barrel of gasoline, but the train 'drinks' too much and takes off into the distance. Forced to hike, after a series of encounters, T and J enter a Swiss Inn. A characteristic Van Beuren musical number ensues. The cartoon ends when the T and J partake of the local delicies, with alarming results.
