Proteus is a legendary narrow gauge tank engine with a magic lamp hung upon his funnel.


Legend has it that should someone find the lamp, their wishes will be granted. Skarloey told this story to the others, which made Peter Sam search the line looking for the magic lamp.

The clues to finding his 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 based on the Talyllyn Railway.


Proteus is painted bright yellow with red lining.

Voice ActorsEdit


  • Proteus appears to have the same model as Sir Handel, which could be why Sir Handel returned in the 10th series. Proteus' model was likely repainted into Sir Handel.
  • Proteus has larger pistons than Sir Haydn and Sir Handel.
  • The Track Master release of Proteus shows him carrying the number 3, like Sir Handel. Ironically, both are based on the same engine and used the same television series model.
  • All of Proteus' merchandise shows him with a nameplate, even though he never had one in the show.
