Harvey (Thomas The Tank Engine)

Harvey  is a tank engine with a crane mounted on top of his boiler, which makes him look rather unusual.

Bio
All the engines except Thomas  teased Harvey at first, but when he was able to rescue Percy  after an accident, they realized 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. He mainly works at Brendam  and the yard, but his favourite place to be is at the Water Works, where he is said to live.

Since his addition to the railway, Harvey's helped after many accidents, but he couldn't do it alone, so Rocky was brought to help.
