Might as well extend beyond Barley Mow towards Pelton, Beamish, Stanley and Annfield Plain. Getting to Pelton would be relatively straightforward if using the old South Pelaw to Consett alignment. Beyond that, you'd need to seek a new route through High Handenhold and Beamish as well as the replacement of two bridges at Shield Row if the line were to follow its original route to the edge of Annfield Plain. Extending beyond Annfield Plain towards Consett would be tricky as roads and houses occupy much of the old trackbed.
