More recently I've been messing around building a small photographic 7mm diorama using some scrap wood and Peco Setrack.
I've based it on an imaginary branch serving Middle Farm (off the Kingswood Wharf branch) of the Duke of Buckingham's Wootton Tramway (Brill Branch) which has been upgraded to take steam locomotives. The original Kingswood Wharf branch retained it's longitudinal sleepered track as the wagons were horse drawn until this branch was truncated by the Met at Church Farm.
The overal dimensions are 1335 x 404 mm and only the base scenery has been applied thus far. The building is a place holder until I construct one from wood.
The sidings hold two wagons and the switch lead (headshunt) holds a loco and two wagons so there's enough to play about with.
A section of the OS map marked with the perceived route (blue). The red line is the Wootton Tramway Kingswood Wharf branch with the Church Siding Junction at the bottom.
Having recently acquired the Minerva Manning Wardle 0-6-0 my intention is to modify this to represent BRILL No 1 as used by the Met prior to the introduction of the classic A Class 4-4-0 tank engines.
There is a bit of work to do as highlighted on the two photos shown here for illustration. More alterations will be required as I progress. I have managed to locate about half a dozen relatively good photos from various sources.
Some of the alterations are: Wider cab; re-siting of the sand boxes; new brakes to replace the wooden ones represented; new steps; additional piepwork; smokebox door dart; lamp iron; etc, etc.
