The Rascals have been hanging around the railroad yard at the
Greenpoint Train Station, but after
Mickey and
Joe set off a runaway locomotive, which runs over
Farina back and forth several times, they get chased off the yard. The gang soons builds their own
dog-powered five-car contraption on an abandoned line of track, earning the wrath of
Toughy,
who has been running his own train nearby. He and a friend set a piano
crate on the tracks, causing a crash. While the train crew clears the
tracks, Toughy uncouples the three traliing train cars, so when the
engine is running again, it circles the track and rams the back of the
train. Mickey and Joe put the train in reverse, which involves a dog on a
treadmill chasing a cat in a cage in the opposite direction, and
successfully go back around the track and recouple the passenger cars.
However, while they are doing this Toughy and his crony remove part of
the tracks. Once the gang's train is running again, this sends the gang
rolling out into the city streets to cause havoc, rumbling through and
past businesses including the
Blacksmith Shop,
Palms Garage, and
Sam Seelig Public Market before inevitably crashing at the bottom of a hill. The kids survive by
bailing out before the crash, but Farina emerges in a daze, seeing
stars and holding his head.
