This post is from the North Wales Train News forum. It describes a telephone conversation between Network Rail Control in Manchester and the narrow-gauge Ffestiniog Railway. The line mentioned in the conversation is a disused standard gauge line linking Blaenau Ffestiniog with Trawsfynydd and was last used when the Trawsfynydd power station was active.
NRC: Hello, it's Network Rail Control here, we've had a report of a
bridge strike on the line between Blaenau Ffestiniog and Trawsfyndd.
We've looked on our map and it's not ours, so we've just realised
that it's probably yours.
FRC: Nope, it's not ours, not if it goes to Trawsfyndd
NRC: You sure? It's certainly not ours
FRC: It's standard gauge track
NRC: Oh really - didn't know that - it's not on any of our maps!
FRC: If it was on our line it'd be narrow guage and heading towards
Porthmadog
NRC: Ah, ok, I wonder if somebody knows if we own this!
................And these are the people that look after our railways
