Cronk-ny-Braaid, or the Hill in the Valley, more famously known as Cronk, is named so as the town was built on a curious rocky outcrop in the centre of the valley leading to the heart of Sodor.
This incredibly defensive structure led to its development into a fortified town. A (now ruined) castle was built here in the twelfth century.
Just to the west is a magnificent viaduct where Gordon once had his dome blown off in 1957. A few miles to the north is a public school and the ruins of Cronk Abbey, both of which are serviced by Abbey Station on the Peel Godred branch.
It was first seen in the Railway Series book Stepney the "Bluebell" Engine where Gordon takes over the train from Duck and Stepney. It later appeared in Enterprising Engines where Flying Scotsman and Donald take over the failed diesels' trains from Henry.
In the television series, it made an appearance in the sixth season episodes, A Friend in Need and Jack Jumps In and in a Jack and the Sodor Construction Company episode, Mud, Glorious Mud, as well as an eighth season learning segment, How Does Emily Get to the Station? It was mentioned in the Jack and the Sodor Construction Company episode, A Happy Day for Percy and the seventeenth season episode, Gordon Runs Dry.
- A siding was added only in the eighth season learning segment, "How Does Emily Get to the Station?" and in Jack and the Sodor Construction Company, a car park for cars was added.
