Bertram

Bertram, nicknamed the "Old Warrior" for his bravery, is an old narrow gauge engine who worked in a quarry on the far side of Sodor.

Bio
Bertram presumably worked the mines on the Mid Sodor Railway, as the narration describes the mine had been worked by the little engines but was run down. Bertram's fate was unknown to many after the mine's closure, and it was assumed he was haunting the mine. Toby found him whilst watching over the quarry one night, and has since befriended him. He now works at the restored mines, taking passengers to the fairground within.

Persona
Nothing is known about Bertram's persona, other than that he is incredibly brave.

Appearances
Bertram only appeared in the fifth season episode "Toby's Discovery" with no dialogue, and was built using Duke's body with Smudger's face.

Basis
Bertram is based on Palmerston of the Ffestiniog Railway.

Oops
According to Britt Allcroft, Bertram was supposed to be a tank engine, but the model crew made a mistake.
