Upstairs was Llangerisech, Nigel Ashton's 2FS layout. In its current incarnation it is basically running re-wheeled proprietary N gauge stock, representing the 1970s.
Expectations were for "somewhere between 50 and 500 visitors". I think the actual turnout was towards the lower end - about a hundred.
From my perspective it was an enjoyable day - the chance to help run Llangerisech, to see a couple of other interesting layouts, chat to other modellers, and to spend some money at the shop.
