Fellow Sussex Downs 009 group member Tim Sanderson was there with his Elmsgate & Thatcham Light Railway, which is surprisingly busy to operate despite it's modest size - I should know, I have had the pleasure of operating it.
Kolne USW (H0) by the Wealden Railway Group took my fancy as a small shunting layout (operated as a puzzle), with added passenger interest, and very nice Scenics. Unusually my son liked it too - he normally likes bigger and busier layouts! This scene is very nicely done - fun by the lake? Take a closer look and all is not what it seems! I didn't notice the sign at the time but Pharmaceuticals company Bayer are a big employer in Cologne.
Nuenbruckenbahn (N, Iris & David Guscott) was an Alps scene with rabbit-warren track-plan, working cable cars, and interesting if implausible scenery. It may offend the purist but it was fun and very popular with the kids (mostly guessing which tunnel the train would appear from), and that in my book is a good thing!
Gorringe Park Depot (00 - Denis Stevens) was a neatly modelled modern-image MPD, a bit of a cliché perhaps but with good reason. I thought the setting looked likely (unlike some of this genre), and this scene combined even more clichés ... I like someone with a sense of humour!
