The Settle–Carlisle line is a 73-mile-long (117 km) main railway line in northern England. The route, which crosses the remote, scenic regions of the Yorkshire Dales and the North Pennines, runs between Settle Junction, on the Leeds–Morecambe line, and Carlisle, near the English-Scottish borders. The historic line was constructed in the 1870s and has several notable tunnels and viaducts such as the imposing Ribblehead.
