The B6259 Hawes to Kirkby Stephen road runs almost parallel to the railway line between Moorcock Tunnel North Portal (Structure ref 257630) to Birkett Tunnel South Portal (structure ref 264300). For the most part therefore access to structures along this length of the line is easy. Many structures can be viewed from the roadside (parking places are readily available) or by way of footpaths and Access land.
