Neville

Neville is an atypically square-shaped black tender engine

Bio
Upon Neville's arrival to Sodor, Thomas saw him with 'Arry and Bert, who were actually teasing him, which caused a rumour regarding him being friends with the diesels and being horrid to steam engines to spread. Percy and Emily thought that he was planning to bump the steam engines, despite his jolly greetings to the engines. Luckily, the rumour was rectified and Thomas befriended Neville after rescuing him from a broken bridge.

Despite his gentleness, Neville has acted a bit cheeky, having once laughed at Emily and paid her back for working with Whiff along with Molly and Murdoch.

Sometime later while working at the Sodor Slate Quarry, Neville told Thomas and Percy about the job of collecting the Sodor Brass Band.

Personality
Neville is gentlemanly, highly enthusiastic and kind, if a little naïve. Neville never holds a grudge, but can be easily hurt by unkind comments or not being accepted by others who judge him only by his appearance. Otherwise, he is bubbly, ready to pull together, and happy to make new friends. He has also been shown to be slightly cheeky in the episode Emily's Rubbish.

In Behind the Scenes with Pierce Brosnan, voice director Jamie Thomason describes Neville as being similar to Thomas, in terms of being around "the same age, helpful, keen, eager and cheerful" and he also describes Neville as being more inexperienced due to being new to Sodor.
