Peter Sam, named Stuart in his younger days while being brought up under the instruction of Duke, is highly enthusiastic, eager, and bubbly. He can be occasionally cheeky, teasing, and a little cocky, but is kind-hearted, well-meaning, and good mannered. He can also be prone to being a little naive at times and perhaps take things a little too literally. Peter Sam has a special funnel which makes puffing much easier, after his old one was damaged in a nasty accident with some trucks that broke free from the incline. With an infectious attitude and high spirits, Peter Sam is almost kind and hard-working to a fault, seldom grumbling about late hours or extra work. He is always nice to the coaches and even the trucks.
