Plot

Leaving for vacation, Mickey Mouse and Pluto arrive at a train station in Burbank, California (home of Walt Disney Productions headquarters). They board a westbound train to Pomona, but are both immediately kicked off by the conductor, played by Pete, stating that dogs aren't allowed (a side gag reveals Pluto's luggage to contain bones). Pete then rambles off the train's destinations and forces his watch to tell him when the train is ready to leave. When the watch does show the time for the train to go, Pete calls, "All aboard!"
