C.B., the Red Caboose, is played by Katie and is PB'd by Adam Lambert. His journal is theredcaboose.

He comes from Starlight Express, and is from some vague point in Act Two of the show - before he gets trashed and decides that he's done one rock'n'roll too many, of course.

He's everyone's favourite caboose with a split-personality, and is based off his original London self.
