Harvey is a tank engine with a crane mounted on top of his boiler, which makes him look rather unusual. He is involved in repair, recovery and industrial jobs on the railway.
When Harvey first arrived on Sodor, all the engines thought he looked different and made him feel unwelcome. He quickly proved how useful he was after Percy had a terrible accident on Bulgy's Bridge. Since then, he has been an invaluable asset to the railway, helping engines back onto the rails, loading trucks, and aiding in repair work.
Harvey is a relentlessly cheery, big-hearted and helpful crane engine. He has a very unusual shape, due to his crane attachment atop his boiler, which he can be sensitive about should other engines make fun of it. However, he is very able to show that his crane is very useful in lifting cargo, trucks, and sometimes some smaller engines.
He has a booming, thoughtful voice and large wooden buffers. He is happy to work anywhere, ready to help clear up after an accident, and offer words of care, comfort, and advice.
With perhaps the most distinctive appearance of any engine, Harvey is painted burgundy with yellow lining and brown, square, wooden buffers. His name is written in yellow on his sides. The number "27" is written on both sides of his crane arm in yellow.
