spent yesterday playing O gauge - luckily I don't have the dough or space.... I have a signalbox and a 1:43 scale van though so I can sort of dream of bigger things..
Chris, Chris, Chris, if I can build Fourgig in 4ft x 1.5ft then what's stopping you? Cost? - handbuilt track, Scalecenes structures, Lima stock (with a LOT of detailing opportunities!)
