I've finally got around to gluing the track down!!!! But the plan got revised again. I laid the track out to do a terminus/ fiddle yard scheme, and, in short.......boring.
So we now have a single track circuit, a passing loop, a three road engine shed, a DMU bay and a four road goods yard.
I'm looking forward to 'playing' with my model trains, and to hell with prototypical realism!!!!
