Regular readers may recall I added a layer of 5mm foamboard on top of the ply to build up the trackbed. I also did this in areas such as the yard, under buildings and under the platform.
This morning I have been making up the platform in order to get it into primer, painted and then to sort out the land around it. I was merrily checking setback of the platform face to track centreline and just thought I'd better check height above rail tops.
It should be 3' and no less than 2'9", so 12mm - 11mm. Mine came out at 15mm, much too high. I had wrongly assumed the Peco concrete platform fronts would be the right height from base of their track.
So out with the demolition tools and up with the foamboard under the platform area.
Came up really easily and cleanly - apart from a very thin layer of card which was stuck to the ply. Far easier than trimming the platform!
Platform structure then needed 2mm adding to it to take it up to the right level. The plasticard packers will also give a bigger area for gluing it down.
Capacity for 2 coaches, just...
I have included a very short section of ramp at the very end to help hide the edge when viewed along the platform.
