In an effort to generate some interest in this section, here is some info on our various efforts, starting with the main OO loft layout. This is a double loop occupying the full depth (front to back) of the loft at a crossbeam height convenient to sit the baseboards on. The layout is just over 2m wide (and about 2.5m deep), that being the size of the ex-Ikea wardrobe panels I had lying around, which happened to just fit across between adjacent rafters. There is a central area for operators, with the double loop crossing between the two sides on narrow sections across the rafters - made to look a bit like a trestle bridge on one side. The larger baseboard is a yard/MPD with turntable, carriage sidings, loco shed, coaling siding and a couple of sidings for breakdown train and permanent way. We will be trying to squeeze in some extra sidings as we currently have nowhere to store larger rakes of goods wagons The smaller board contains a station and goods yard with goods shed and small loco shed. Everything is currently analog, split in to four control 'zones' - outer loop, inner loop, MPD/yard and station/goods yard, each zone controlled by part of a HM2000 + left and right HM2000+ controllers. Rolling stock is a complete mish-mash of things which take Josh's fancy, although it is possible to run a full LNER or BR setup (although we also have some GWR and a Hogwarts Express!). Very much a work in progress, we have only recently (a couple of months ago) lifted the original temporary track setup, cork boarded the entire surface, cut the turntable well and permanently laid the track.
