Good update overall Matt, seems to be coming on quite well, the abandoned line is quite a good idea as for the name not got anything really, just name it what you want to.
Purr, mew. I'm a cat lover myself, hence why I thought of the name Cat Valley Steam Railway for my 00 gauge railway in my bedroom. How about Goldfish Garden Railway? Who's the lucky black cat living with you? I'd like to make her acquaintance if I may. You've gone larger in size with track, I've gone smaller in size: N Gauge.
