Harvey

Harvey is a crane engine: he has a crane arm mounted on top of his boiler, which makes him look rather unusual. The other engines teased him at first, but when he was able to rescue Percy after an accident they realised that his difference was what made him special. Since then, he has proved very useful, using his crane arm for maintenance, building and clearing up.

With perhaps the most distinctive appearance of any engine on the show, Harvey is painted dull red, with some gold. His name appears on both his sides, as well as the number 27 – which, including the Narrow Gauge engines and excluding Diesel, accurately reflects him being the 27th addition to the fleet of engines working on Sodor.

Harvey is based on a real crane engine - No. 4101. He first appeared in Season 6.
