Duke: He often pulls tourist trains to the "supernatural" locations on the SKR, from Duncan's bridge to the tunnel where it's said you can see Proteus' light
Peter Sam: He finds food fascinating since he cannot eat it, instead learning about it's intricacies through his good friend, the refreshment lady

Duncan: He has a chain connecting his nose piercing to his handrail. Due to the sheer size of it, he has a few keychains hanging off of it, including some pendants with his workers and fellow engine in them
