Continuity mistake: Baxter and Beecher are riding in a horse-drawn wagon. As they go across a bridge, the train carrying the Marx Brothers approaches. Baxter and Beecher leap off the bridge, one jumping to the right and one jumping to the left, but they are side by side when they land in the river below.
Continuity mistake: The train that the Marx brothers are driving is a locomotive of a 2-8-0 wheel arrangement. However, when the train runs off the track, the locomotive is portrayed by a 2 truck Climax type engine of a 0-4-4-0 arrangement. Then, the train reverts to the 2-8-0 once it returns to the tracks.
