Jake is a steam engine who appeared in the episode The Runaway Train. He was seen pulling a royal carriage to Oakford station. Budgie first meets Jake and delivers more coal for him. When Budgie and Pippa tried to warn a impending rockslide, Jake's brakes fail. Luckily, Budgie is able to clear the rockfall and then helps to divert Jake on a runaway siding in time.
Jake is painted in a light green livery with gray wheels.
Although Jake has no specific basis, it is possible that he is a tank engine so he is shown to have a coal bunker attached to him.
