I remember the 160 and 163.
New Lambton to Sunderland.
Ended up being Cadet workings until the services were withdrawn.
Redby ran one and GNE the other, in the mid/late 90's. Then GNE got them both.
They both missed Grasswell out though. One passing Shiney College and the other via Newbottle after coming through Fencehouses and Sedletch Road.
