Porky is informed that his beloved Train the 13 1/2 named Toots, his engine, is to be replaced by a streamline train by the name of The Silver Fish. After the driver of The Silver Fish insults Toots, Porky mutters that his train could easily take on the steamline train. The driver agrees to a race that ends with Porky being the victor (thanks to a bull seeking revenge on Porky after previously being insulted by him) and becoming the new driver of The Silver Fish whist a battered Toots is on a trailer behind with Headin' for the last Roundhouse' written on a sign attached to it.
