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

- 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.
