Alan, I've got three other cunning plans on at the moment, what are you waiting for! Seriously if you want some more detail on anything from my build I'll happily pass it on, I've got plenty of sketches and a CAD drawing that have helped me get this far...
Paul, yes behind the sofa. Rather than a loop my daughter and I built an end to end line at my Mum's this afternoon. The wagon would look great on you line, and it does R1s!!
