I'd just like to clarify an important, point. The baseboards were built by Dave, a key member of our group, and the "box of tricks" was built by Steve C, who is the only person I know who could have done it. He also mastered Templot and produced the track plan, overlaying on the OS map and giving us templates for the points.
For those interested in these things the layout is DCC controlled and the control panel uses a CML electronics module to allow push button control of points and signals. It also sets any one of 12 routes using just one push button. All DCC equipment is by Digitrax and point motors are Tortoise. As Frank says, the plain track is C&L but we built the points using Templot and copperclad sleepers as they were pretty much all non standard and include two scissors crossovers and a double slip. Point work was built by myself and Dave.
Ballast is Woodland scenics 'N' scale, a mix of buff and brown, but the ash ballast in the yard area is fine sieved sand.
Signals are mainly from MSE components, still awaiting LSWR finials in some cases and operated using servos and the brilliant GF control units giving slow pull off and bounce on return.
The first building has now been completed and installed, the goods shed. This and future buildings will utilise a new (to me anyway) material called Foamex ( not to be confused with foamboard) which gives great rigidity but is very light and easy to cut. If anyone is interested I'll try and post some pics.
