Thanks Noel. These are laser-cut wood kits from Timber Tracks which are beautifully presented and straightforward to assemble with their fast-setting wood glue. They are amazingly strong when complete. These models are destined for my new O gauge steam outline layout "Buffers Lock" which is in planning - a cross between my "Shunters Yard" and "Diesel Depot"! The boards and wiring will be done to the same high standards as "Little Siddington". The idea is to have an interesting O gauge layout that can be set up quickly for play at home/clubroom and easily transported in two cars to exhibitions.
