Stepney later wanted to have a change from his branch line and he was sent to help Toby and Mavis at Anopha Quarry. This excursion nearly ended in disaster after 'Arry and Bert tried to scrap Stepney, luckily without success, after Stepney accidentally ventured into the Sodor Ironworks. Stepney later helped Edward with the running of The Loop Line and was accidentally bumped into by Duck, who was looking at The Hot Air Balloon. He was last seen in the twelfth season, when he was hit by a truck of sugar in an incident caused by Rosie.
Stepney is a bubbly, honest and humble chap who is busting with enthusiasm. He is very eager to please and is every engine's friend. Even if an engine might not like him at first, his personality wins them over. 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.
Stepney is based on the real engine of the same name, an LB&SCR A1X Class "Terrier" 0-6-0T tank locomotive.
Stepney is painted in the goldenrod locomotive livery of the LB&SCR, formally known as "Stroudley's Improved Engine Green".
