Edward (voiced by William Hope) is a blue mixed-traffic engine.
Edward is kindhearted and always keen to help a friend in need. The small engines trust him to lend a listening ear and sympathetic advice. He is a hard worker too, and always does his best to finish a job.
Sadly, the big engines often see Edward as old-fashioned and slow. While it is true he is the oldest engine on the North Western Railway - it must be noted he helped build it - he has proved time and time again that he is more than capable of working as hard as any engine, but he is a more clever and wiser engine, too.
Since the sixth season, Edward's persona differs slightly. Despite his reputation of being kind and friendly, Edward has sometimes seemed to act cheeky. Edward has also acted with a lack of confidence in himself in that he keeps secrets from the other engines and the Fat Controller, when he was once leaking steam and likewise when he was told to pull the post train whilst Percy was being repaired. Sometimes, Edward has seemed to share the same personality as James, such as when he decided to show off his special waterwheel and laughed at Thomas when he was wearing a funny funnel.
