The Wensleydale Railway is a tourist and heritage line starting at the County town of Northallerton to Redmire on the edge of the Yorkshire Dales National Park, passing through the Georgian market town of Bedale and the Dales market town of Leyburn, with constantly changing scenery, from the arable lands of the Vale of Mowbray in the east to hills of the Yorkshire Dales in the west.

The railway in Wensleydale is a remarkable survivor. Having lost its passenger services in 1954, and almost half its route mileage by the early 1960s, the line survived until 1992 by carrying limestone to the smelters on Teesside. When this traffic finished, the Ministry of Defence decided to use the line for the occasional transport of military vehicles. This kept the line alive for just enough time for the Wensleydale Railway Association to build, support, and eventually form a company to take a 100-year lease on the 22 miles of line from Northallerton (Castle Hills) to Redmire.

The line is a predominantly heritage diesel line, with  steam services operating over selected weekends, special events and the summer months. For further information please see the timetable page for days on which the steam service runs.
