One of my favourite designs on Carl's micro site is 'Endal Street'.. an ambitious shoebox plan from Jon Songoygard in Norway.
It features dual gauge track running through cobbled streets and overhead electrics. In a moment of madness I thought I'd give it a go! (Like I haven't got enough started)..
I figured it might be quite nice to try and build it using foamcore and card/paper. The turntable and sector plate might present some difficulties.. but I'll worry about that later.
So far, box built, track built (soldered construction). Next step.. worry about the turntable and sector plate!
