>>1034949As in last image post (isn't full length though) and few earlier ones, I just keep two large boards that take up most of the dinning room but can easily be packed up and go straight back under a bed with a dust cover over them. Haven't laid one or fitted the underframes yet but it's easy to move around and still a decent size to run larger medium-sized rakes. Most of my rolling stock though I'm building up for my local club layout that's going on the exhibition circuit from next year or 2018 onwards depending on when it's finished. That's a very large 1.5 x 7 meter one though, so looks fine with full size rakes.
N gauge is really the way forward for small spaces, convenience and mobility as both range and choice of manufacturers are getting closer to OO. Good few options though:
Modular systems are one; quite a few companies and individuals now make them to order or sell their own modular systems in sections. I saw some great ones from traders and bespoke manufactures at the International N Gauge Show earlier this year but they don't come cheap. Best one I saw came fully landscaped and started at £150 ($187 for burgers) per modular section.
Cheaper alternative is build your own one in pieces that are easy to store. Just need to be careful and make sure you get the joints right if there's a lot of sections required.
Finally if you don't want a fixed layout but something you can do more than make a basic oval with, there's always Kato's track system. As with modular options, it's not that cheap, but for a temporary and fully adjustable track system in terms of quality, convenience, choice and the ton of extra accessories on offer it's unmatched. A basic double track oval with passing loop can quickly turn into something much bigger whenever you feel like adding to it.
