Shen Valley is a valley that first appeared in the ninth season. Percy took the famous artist here while looking for the Spirit of Sodor and the artist complained that it was too green. Thomas once took the Fat Controller for a picnic here but the grass was muddy. In the tenth season, Thomas took Skarloey here during a tour of the Island.

Shen Valley is located in the west of Shen Ven, along the Peel Godred Branch Line in between Abbey and Hawin Lake.
