Kirklees Light Railway - Whistlestop Valley

Whistlestop Valley, formerly the Kirklees Light Railway, is a visitor attraction featuring a 3 1⁄2 mile (5.6 km) long 15 in (381 mm) gauge minimum gauge railway. The attraction's main site is in the village of Clayton West in Kirklees, West Yorkshire, England which was first opened to the public on 19 October 1991, with a second, smaller site in a rural area near the village of Shelley.

The railway at Whistlestop Valley runs along the trackbed of the Lancashire & Yorkshire Railway's former branch line, from Clayton West via Skelmanthorpe to Shelley Woodhouse (a few yards close to the former Clayton West Junction near Shepley) on the Penistone line from Huddersfield to Sheffield via Penistone and Barnsley.

From 1991 to 2021 the attraction was known as the Kirklees Light Railway. In June 2021, the attraction was rebranded under the name Whistlestop Valley but retains the name Kirklees Light Railway for its 15 inch railway operation.
