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 line is a predominantly heritage diesel line, with steam services operating over selected weekends, special events and the summer months.
