Peter Sam
Peter Sam is a happy and kind engine, but is a little vulnerable and often teased by the others. He, like Sir Handel, was tutored by Duke and has great respect for him deep down, despite ribbing him about his age. A hard worker by nature, Peter Sam seldom grumbles about late hours or extra work.
Fun Fact
Peter Sam was actually known as Stuart, but was changed when he came to Sir Topham Hatt's railway.
