I refer to the recently installed section of high-level base board — see my post #336. However, some additions are required to this part in the darker grey:
The already-built adjoining section of retaining wall has a narrow strip of high-level base-board included in its construction, which will add an extra couple of inches to the width of the higher level. This provides the space for the head-shunt for the centre road and platform 2. One small further addition is required to the high-level base-board in this section, at the position shown ringed in red here:
A small forward extension to the high-level base-board is necessary at the position shown to accommodate the alignment of the track connecting platform 2 to the main running circuit and the point lever for the turnout giving access to the head-shunt. Having looked at various real railway retaining walls, often any repairs, alterations or extensions are in a different style to the original wall.
All of the wall made to date is of the same pattern, as seen here:
I shall make the retaining wall for the forward extension in a different style:
The retaining wall built so far is made of recovered vintage material with over-scale impressed bricks. It will look odd if the new section I am about to build has much smaller (= scale) bricks. So I will use material made for me some years ago by Poppy’s Wood Tech. This is plywood with a laser-cut brick pattern, but with bricks of the same dimensions as used by Milbro in the 1930s.
I have started making the buttresses I will require:
Generally, it will be easier to lay the track on the high-level base-boards behind Cavendish Goods before fixing the retaining wall in place. However, this small forward extension has to be built and installed before I can lay the track connecting platform 2 to the main running line. Hence, I have started the work needed or track laying on the high-level will be held up.
