Kevin is a well-meaning, but clumsy four-wheeled crane who works at the Sodor Steamworks.
Making his first appearance in Hero of the Rails, Kevin works at the Steamworks with Victor, offering help whenever possible. When Spencer was sent to the Steamworks after getting slate in his funnel, Kevin distracted him by dropping parts all around while Thomas took engine parts to Hiro. He later participated in Hiro's official restoration. Thomas was once put in charge of the Steamworks when Victor went to visit one of the Narrow Gauge engines and Kevin helped Thomas fetch parts. However, Kevin got so busy that he became confused and accidentally pushed a button which sent Spencer up in the air on the gantry crane. Soon Victor arrived and helped restore order to the Steamworks.
Cranky once had too much work to do at the docks, so Kevin was sent to help out. Unfortunately, Cranky didn't want Kevin's help and told him to stay in a corner out of his way. When Cranky dropped a load of pipes and a cage full of chickens, Kevin rushed to help. This made Cranky even more cross. Thomas and Salty tried to show Kevin that Cranky did have a heart of gold deep inside, but were unsuccessful immediately. When Cranky knocked over a barrel, Kevin tried to help but ended up falling into the sea. Luckily, Cranky fished him out of the water, but not before The Fat Controller arrived and saw what had happened. He was about to send Kevin away in disgrace when Cranky spoke up, defending Kevin and proving to them both that he really did have a heart of gold. Together, Kevin and Cranky got all of the work at the Docks done. Later Ben tricked Kevin so he could be painted blue just like his twin, Bill so they could deceive Connor again.
Kevin later became fascinated with the snow, and decided to play around in it despite Victor's warnings, but got stuck outside the Steamworks until Thomas spotted him waving his crane arm round, not knowing that Victor went out to search for him.
Kevin is a young, bubbly, enthusiastic crane who works at the Sodor Steamworks, where he assists Victor in repairing engines. He is innocent, well-meaning, bursting to help and say hello, and always eager and ready to lend a helping hook. Kevin is often seen dashing about and tends to be quite clumsy, having a habit of frequently dropping things from his hook and pranging objects as he buzzes about. He often exclaims that it was "a slip of the hook". Something that he says often enough for Victor, who he refers to as "boss", to be able to commonly finish the sentence for him. But Kevin is loveable, kind-hearted, and funny, if rather naive, and always tries his best, regardless of his inexperience.
Kevin is painted in a yellow livery with black warning stripes. His hook and brake are red. He has the Sodor Steamworks logo painted on his cab door.
