As NR are currently doing a reorganisation around routes. e.g. each route lets say West coast will be a semi autonomous organisation. its therefore not inconceivable that lets say FGW takes a franchise to run the route ( track, signals, stations etc ) and the trains for South west !!!!!!!!!!!!!!!!!!!!!

That would take us back to the pre British Rail days when you had GNER, Great Western etc etc

Personally I'm not sure if that would be good or bad.

I think you mean LNER

I do.
