The Double Hills

The Double Hills are a set of two steep hills on the North Western Railway. It is currently unknown exactly where on the Island of Sodor they are located.

It was here that Stafford's battery ran out while trying to keep up with Spencer, where James' sheep got loose, and where Thomas' brakes failed.
