D199 attempts to help Donald and Douglas after having his diesel tank drained of beer, but they Scottish Twins stubbornly refused do to them not trusting him. However, when they later got stuck on a collapsing bridge, he came to their rescue. Although he was able to save the twins, the bridge finally collapsed under him and D199 fell to the water below. Donald and Douglas were happy that he saved them, but felt guilty for being so rude to him. D199 was eventually fished out of the river and was awarded by the Fat Controller by being purchased for the North Western Railway and given a new name, which was Ted.
