This was supposed to be a mock up so I could work out how the railway was going to cross the shed door to form the circular layout I wanted. Then the mock up worked so well, I just got stuck in!
I was determined to have a Walnut Tree style viaduct, all girders and spindly, with the valley far below. The valley you see here is only 20 cm below the bridge deck simply because when I made the valley deeper, the valley sides would have exceeded 45 degrees and it just looked wrong! I wanted the valley to have the following....a double track railway line (an early competitor to the Gwynraven line), it also had to have a river, a main road and a garage. This makes the valley floor quite cramped which is typical of the Eastern Valleys Lines around Blaenavon. I took great care to make this module to scream South Wales, even if there was no loco or stock on show.
The road,river and railway line are on a skew to add scenic interest. The railway line in the valley is cut in to the valley side and will feature a retaining wall. on the right side of the railway line is the river. There will then be a stone wall and then the road with it's Esso Garage.
The viaduct deck is 3mm ply. It is going to rest on brick pillars, one of which is in the middle of the viaduct, squeezed between the river and the road. The girders are probably going old Peco ones as I have some to recycle from the old layout.
The whole unit is a lightweight box which lifts in and out and can be bolted into place also.
All in all a successful bank holiday.
