My entry in the wiring competition, definitely installed using KISS principles - whilst the underside of the boards has not been painted, they were varnished.
This week's layout building activity has been limited to putting together and installing the siding gate. Whilst it may look a little over engineered for such a task, this is because in the interest of thrift the company used a cut down damaged level crossing gate. It is currently digitally powered - I push it open with one of my 10 digits (fingers).
The wall has been started using some surplus DPM modular wall panels, left over from a previous O scale USA layout. These have been clad to bring them up to the required size and will then be finished using Redutex Weathered red or blue brick.
