Black Loch (also known as Castle Loch) is a famous lake near Callan Castle, crossed by Castle Loch Causeway.


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).[1]

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.[2]
