Bertram

Bertram is an old tender engine who worked on a quarry on the far side on the Island of Sodor. He is known as the 'Old Warrior' because of his bravery. Toby found him whilst watching over the old mine, and has since then befriended him. He now works at the restored mines, taking passengers and children to the fairground within. He is number 9 on the Skarloey Railway.

Bertram only appeared in the Season 5 episode 'Toby's Discovery' with no dialogue, and was built using Duke's body with Smudger's face and painted dark brown. He is based on Palmerston from the Ffestiniog Railway. According to Britt Allcroft, Bertram is supposed to be a tank engine, and the model crew made a mistake.

He was not seen since Season 5.
