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 Railwayand 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 became firm friends. Bertram was later restored, and became responsible for getting passengers to and from the mine and the castle, taking passengers to the fairground within.


Not much is known about Bertram's persona; 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.
