“This is your ghost, Toby. His name's really Bertram. But we call him "the Old Warrior" because he's so brave.”
―The Signalman introducing Toby to Bertram[src]

Bertram, nicknamed "The Old Warrior" by the railway staff because of his bravery, is an old narrow-gauge tank-tender engine who worked at the mines. He lived on a remote part of the Island that was once very rarely visited.


Thomas & Friends

Bertram used to work at the mines, near the Mid Sodor Railway and Tidmouth Bay. His fate was unknown to many after the mine's closure, and it was assumed he was left to rust. He remained at the mine until it was rediscovered years later.

Over time, he became legendary; many knowing of the "old warrior ghost" haunting the mine. However, one night Toby discovered Bertram whilst watching over the mine and castle, which were being restored to accommodate visitors. At first, Toby thought Bertram was a ghost, but the two have since become firm friends. Bertram was later restored and became responsible for transporting passengers to and from the mine and the castle, taking passengers to the fairground within.


Not much is known about Bertram's personality; however, it is said that he is very brave and that he and Toby are firm friends. Toby states that if there are any ghosts at the mine, they certainly make the place feel very happy.

Technical Details


Bertram is based on Prince, a George England tank-tender engine from the Ffestiniog Railway at Porthmadog, North Wales. Unlike his basis, Bertram is built to 2ft 3in gauge, while Prince is built to 1ft 11½in gauge. Duke is also based on Prince and has the same modifications as Bertram.


Bertram is painted dark brown with red lining.

In some of his merchandise, he has two brown or red nameplates on the sides of his saddle tank with his name painted on them in gold. Bertram's original Wooden Railway toy depicts him with a red cab roof, domes, and lining. He also has a black letter L in place of his nameplate on both sides.
