Wilbert Awdry
Thomas had his genesis in a wooden push-along toy from the early 1940s made by Wilbert Awdry out of a piece of broomstick for his son Christopher. This engine looked rather different from the character in the books and television series and was based on an LNER Class J50, which was going to be his originally intended basis, with smaller side tanks and splashers. He was painted blue with yellow lining and carried the letters NW on his side tanks.
