Proteus

Proteus was a very old engine from the hills of Sodor with a magical lamp. Legend has it that his lamp was magic and if any engine ever found it, their wishes would come true. The clues to finding the magic lamp are feeling a rush of wind when the lamp is near, hearing a strange creaking sound, and see a flickering light that shines on and off. Proteus is painted bright yellow with red lining. All of Proteus' merchandise shows him with nameplates, even though he never had any in the television series. Proteus' TrackMaster model depicts him with gold side rods instead of his original, silver ones. Proteus has also appeared in various magazine articles.
