We're only making plans... for micro
I'm very fond - perhaps obsessed - by minimum space/micro layouts whatever the scale/gauge.
Mr Carl Arendt's excellent website, Micro/Small Layouts, is (in my opinion) the best thing on the www. Packed with ideas and inspiration - great stuff.
Using foamboard, here is a tuning fork style micro in O gauge, 63" x 10" (40" scenic). Shunting is in the hands of a Class 35 Hymek, DCC fittted by Howes with sound. I still have some work to do; frame it in, use of a mirror at one end maybe, more weeds. Bits and bobs.
