Not any more, Alan
The old Up line was the only one still in situ south of Whitwell for many years, but all remaining track was lifted in 2012. Some was intended for the Borders line, some was offered to local preservationists, but the rest was simply recovered for recycling. One of the reasons it was lifted was that a fair bit had already been stolen by 'metal fairies', but in truth, although the formation is officially protected, all the track would have to be lifted anyway for remedial work to be carried out on the formation, which has suffered badly in some areas from subsidence and the actions of burrowing animals. The section between the A1(M) bridge and Shincliffe is bad - an area where there was originally a trestle bridge, I believe, which was simply filled in to make an embankment - and in the area of Broomside Junction there is a lot of subsidence too. There's the odd signal post still extant, and a few telegraph poles, but that's about it these days. There's still a stub from Tursdale Junction to just by the old NCD workshops, but that's really where the recovery trains were being loaded at the south end, back in 2012. The points at Tursdale are clipped out of use now. You can see a small amount of track at the north end from Pelaw heading towards Follingsby, but that doesn't go far either. I was at Penshaw in late September; the old junction is a wasteland now. All along the route, trees and bushes are rapidly reclaiming the formation too, even though much of the ballast still remains.
