Oscar and Grundgetta argue over the letter X and a train. They tell Gordon they're actually preparing for a song about the X Train, a favorite method for Grouch vacations. They're backed up by a pair of Grouch conductors (Richard Hunt and Martin P. Robinson).
Portions of the song borrow from "Chattanooga Choo-Choo."
