Thomas the Tank Engine Wikia

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


Thomas & Friends

Proteus was a very old engine from the hills of Sodor with a magical lamp, and the legend goes that 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.

In the ninth series, Skarloey told Proteus' story to the other narrow gauge engines and Thomas. At first, Peter Sam scoffed at the tale, but almost thought he discovered the lamp himself. He later realized that maybe just believing in the lamp will grant your wishes.

In the twelfth series, Miss Mary Marvel, a famous storyteller, read stories about the legend at a special show. Later, Peter Sam found a neglected statue of Proteus that was lost for many years. The statue was then restored and is now preserved in a park near the Skarloey Railway.

Technical Details


Proteus is based on the Talyllyn Railway's Sir Haydn, a Hughes Falcon 0-4-2ST. Sir Handel and Albert share the same basis. However, his cylinder block, wheels, and valve gear are based on a Kerr Stuart Tattoo Class 0-4-2ST, the same basis as Peter Sam.


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.


Official Description

From Official Media[1]

Proteus: Proteus was a very old engine from the hills of Sodor with a lamp that was so bright you could see it for miles. Legend has it that the lamp was magic and if any engine ever found it, their wishes would come true.


  • Proteus is likely named after Proteus, a legendary sea-god from Greek Mythology.
  • The statue of Proteus is missing his signature lamp.
  • Some TrackMaster releases of Proteus show him carrying the number 3, like Sir Handel. This may have been a factory error of using Sir Handel's TrackMaster model with a different face and added headlamp or same tooling.
  • His Wooden Railway and TrackMaster toys depict him with nameplates despite not having any in the TV series.
  • Despite that he never spoke in the series, his first speaking role was in Thomas & Friends Storytime and he's voiced by Keith Wickham.
