Axel is a Belgian engine.
Axel, along with the other international engines, accidentally arrived on the Island of Sodor when the ferry they were travelling on stopped at Brendam Docks instead of the Mainland. He was the engine approached by the Dock Manager to explain their presence and was informed they had got off at the wrong place. Embarrassed, Axel proceeded to order the other engines back onto the ship.
Axel competed in the Great Race alongside Gordon, Flying Scotsman, Spencer and Etienne. He spent the majority of the race in last place, but after Scotsman slowed to express concerns on the explosion of Gordon (known as the Shooting Star at the time)'s boiler, managed to overtake both Gresleys and finish third. He returned home after the show was over with the other international engines (bar Ashima).
