Stepney is a bubbly, honest, cheery chap who is busting with enthusiasm. He is very eager to please and is every engine's friend. After being saved from scrap by Rusty and the Bluebell Railway, he now runs his own branch line, but loves helping out on the Fat Controller's Railway. He has an enthusiasm for learning and listening to advice, as well as keeping busy. Stepney can feel down in the dumps if he does not get enough work to do or if he does not get a good long run to stretch his wheels. Stepney is high-spirited, lively, and is keen to see fair play. He is popular amongst the engines and is always game for more work.
