 Porky is the engineer on the most pathetic train in the fleet. After some routine episodes (using pepper to get the engine to sneeze itself up a hill, chasing a cow off the tracks, only to discover too late that it s been replaced by a very angry bull), Porky gets word that he s going to be replaced by the new streamlined Silver Fish. He insults it under his breath, but the Silver Fish engineer hears and challenges him to a race. The angry bull catapults Porky to victory.
