Biography in the SC Shorts

In another SC Short called "The Gay Race", 451 was one of the contestants who participated in the race, and it was revealed that his name was "451". In the next SC Short "James the Splendid Stupid Stuck-up Stunt Engine", 451 was talking to Percy about his dirty looks, until James crashed into Percy. Then James crashed into 451, but he beated him up for it. In the short "Snow Is Nothing But Trouble", 451 was racing across the snowy island when he crashed and flew into the air, clearing a snow pile while he was at it. He accidentally found out who was in the snow drift while talking to Jack and Jock. Spencer once told 451 to keep his distance in case he made his paint sooty, but 451 pointed out that his job requires him to get sooty and Spencer does not know that because he is too full of himself. When Spencer had to pull freight cars, he decided to "show 451 how a streamlined engine pulls freight cars", but he ignored a "Go slow" sign and had a horrific accident. 451 apologized for teasing him and Spencer apologized for being too full of himself.
