Pie in the sky idea and there's no economic reason to build it either. There's other towns in the North East which are much higher priority Washington for example or the West End of Newcastle or South side of Sunderland both which would offer a much better return for not much difference in costs since it's just building a new line. Other than Stanley, there's nothing between Consett and Newcastle.

I live near the B&T line and the only reason that works is because the line already exists so it's easier and much much cheaper to do.
