There you go... Thanks for that.
When the railways were nationalised, as long as the guage was correct, I assumed anything could go anywhere so to speak.

Again, I always assumed the one West of Pelaw, that cut through Leam Lane Estate, went through where Wrekenton Golf Course is and around the back of Harlow Green towards Eighton Lodge was the one that ended up towards Dipton, rather than the one from Bowes that split near Long Bank (with one joining the ECML and the other going across the Marshalling Yards towards Kibblesworth). But thinking about it, these two probably joined up together at some point further west.
