Once Farina manages to climb aboard himself, the kids attempt to stop the runaway locomotive, but have no luck until the engine crashes into a grocery truck.
As it turns out, however, the entire incident is revealed to be a dream Farina had as Joe and Chubby's father lectured the kids about rail-yard safety.
The film marked the first appearance of Norman Chaney as "Chubby", having won a national contest to replace Joe Cobb as the Our Gang "fat kid".
Railroadin' has since been released on DVD as well, but was never added into the Little Rascals television package, despite being restored to sound.
The train yard scenes were filmed at Redondo Junction just south of downtown Los Angeles.
