|“||"People say I'm old fashioned, but I don't care. The Fat Controller says I'm a useful engine."||„|
|~ Edward to Trevor the Traction Engine, Saved from Scrap, 2nd season of Thomas & Friends, 1986|
Edward the Blue Engine is one of the oldest engines on the Fat Controller's Railway in Thomas the Tank Engine & Friends. He is reliable, helpful, kind, friendly, and very wise, and proves to bigger engines of how really useful he is. Whenever there's trouble, it's Edward that Sir Topham Hatt turns to to restore order. Like James, Edward is a mixed-traffic engine, meaning he can pull coaches or cars respectively. He often works as a back engine, helping push heavy trains up Gordon's Hill. Edward also has his own Branch line which he runs with help from BoCo, and sometimes Donald & Douglas.
Edward is based on the Larger Seagull K2 (21 class) 4-4-0 from the Furness Railway. He is the protagonist, later supporting deuterogamist in The Adventure Begins.
Edward overall is kind-hearted, helpful, clever, friendly and a very wise engine. Besides, he is one of the oldest engines. He admits that he has never broken down in ages and proved to be very reliable. He is a hard worker too, and always does his best to finish the job. If ever an engine misbehaves or acts out, it's Edward that the Fat Controller turns to in order to soothe things out. In the Adventure Begins, he is a mentor to Thomas the first time he arrives on Sodor.
However, his persona slightly changed from the seventh season until the fifteenth season, almost close to make him out of from his true character. He acted cheeky like Thomas, had a lack of confidence in himself in that he keeps secrets from the other engines and Sir Topham Hatt, when he was once leaking steam and likewise when he was told to pull the post train whilst Percy was being repaired. Sometimes, he acted in a way similar to James.
His original persona returned in seventeenth season. In eighteenth season, especially in episode "Old Reliable Edward", Edward is shown to be sarcastic and to have a limitation to being patient towards Gordon who never said "Thank You" to him after helping Gordon to give him a push up the hill. After Gordon was tricked by Thomas, Edward sarcastically teased Gordon in that he is not really reliable due to always being stuck on his own hill, and due to always calling Edward "Very old and unreliable". Even so, in the end, Edward helps Gordon up the hill and Gordon finally thanks Edward.
