Neville is a kind, ubiquitous, black square-shaped tender engine. When Neville first arrived on 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 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.[1
