The story so far...
Shortly after my father passed away a few years ago, leaving me his lovingly built n-gauge line based on a fictitious Isle of Arran railway, I decided that model railways didn't have to mean mainline tail chasing, despite the fact that the last layout he and I had worked on together ( some 30+ years ago) had allowed us to run a full length 'Queen of the Scots', 20 truck coal trains and so on, and look right.
Full marks to him, having never actually had a model railway
