Neville is a black tender engine, who works on the Norramby Branch Line.
The engines did not like Neville at first. Although he was kind and friendly, Neville had the misfortune of looking like a Diesel. Thomas saw him with 'Arry and Bert and soon a rumour spread that he was planning to bump the steam engines. Luckily, the rumour was rectified and Thomas befriended Neville after rescuing him from a broken viaduct.
Sometime later, Neville told Thomas and Percy about the job of collecting the Sodor Brass Band.
