I've got a fair amount of LGB track in stock. It was bought with the short-term intention of using it to run-in Peter Jones and to visualise some possible locations. The longer-term intention involves grandchildren and a well known blue engine. After all, I started off with the old Meccano clockwork Percy.
I had been shifting towards hand-building the track from day one. Issy's latest enthusiasm (Poop Poop said Mrs Toad) means I'm going to be time poor for the rest of the Summer which has put paid to that plan. I've also got a nascent idea for a better location for the line in the long term and I don't see the point of building track until then. So I'm back to using LGB as my proof of concept and to get some sort of 7/8ths line in place to help my thinking.
I'm also warming to that idea of a little 16mm line in one of the raised vegetable beds. Teddy seems quite supportive of the concept.
