Black Loch

Black Loch is a branchline that Emily runs. James was originally given the run but was replaced with Emily when she was late with the flour train once to often. Originally, 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. But Emily learns that the monster is actually a family of seals and the engines now like taking this route.
