Mickey's Choo-Choo is a 1929 Mickey Mouse short animated film released by Celebrity Pictures, as part of the Mickey Mouse film series. Ub Iwerks was the animator. It was the eleventh Mickey Mouse short to be produced, the eighth of that year, and was one of the series of early Disney cartoons that led Mickey Mouse to become a national fad by the end of 1929. Originally produced in black and white, this cartoon was one of 45 Mickey Mouse cartoons colorized by American Film Technologies in 1991.

Plot

The cartoon opens with Mickey piloting an anthropomorphic 2-2-0 steam engine, ringing his bell and blowing the engine's whistle. As the engine and its coal tender back to collect a boxcar, the engine rests with Mickey, its railroad engineer, fuelling it, and feeding his engine with coal from the tender. As the engine eats too much coal and burps, Mickey decides to have some spaghetti, until Minnie comes along. After Mickey finishes his lunch, Minnie arrives with a violin that she can play, and hops onto the freight car. Minnie plays a musical song (Dvořák's Humoresque) while Mickey does the same. As Mickey looks at his watch, only to realize that they are late, he yells 'All aboard!' to the engine, which whistles in cheerful response after Mickey gets on board. The engine slowly starts out of the station and chuffs cheerfully through the beautiful countryside toward a hill and struggles up it. The engine ends having problems and starts to cry. The cartoon ends with Mickey pushing the boxcar so hard that it comes loose from the engine, runs into a cow, and explodes into a tree. In the final shot, Mickey and Minnie ride a handcar into the sunset.
