Spencer the Silver Engine

During his first visit to Sodor, Spencer took the Duke and Duchess of Boxford on a trip around Sodor. He ignored Gordon's warnings about taking on water and thus ran out - Spencer attributed the incident to a leaky tank.

Upon his next visit, Spencer challenged Edward to a race and maintained a lead for the majority of the race, but vainly fell asleep while the Duke and Duchess stopped to take photos and lost to Edward, after Edward got onto the summer-house branch first.
