Black Loch is a famous lake near Castle Loch Causeway and Callan Castle. It is located on the Misty Valley Branch Line.


Thomas & Friends

In its first appearance, Donald and Douglas got trapped here whilst taking a heavy goods train to Callan Castle. They were soon rescued by Harvey (whom they initially mistook for the Loch Ness monster since they are from Scotland and there is the monster).

James was originally given the passenger run, but was replaced by Emily when she was late with the flour train once too often. At first, the engines were worried about the route, as it was rumoured that the loch was occupied by a monster and that boulders would bash engines' buffers. When Emily took the Black Loch run, however, she learned that the monster was actually a family of seals, so the engines now enjoy taking this route.



  • The Black Loch monster is based on the legendary Loch Ness monster (alternatively known as ‘Nessie’).
  • The location was originally known as Castle Loch.
  • The Black Loch Folly is now on display at Drayton Manor Theme Park.
