I emptied the kitchen cupboards to weight, it worked very well
All the risers are in place now, i have a bridges to build now to cover the gaps.
The Turntable will sit here, about 7 inchs higher. My next move is to infill the middle section to get it up to the correct height. The piece of paper is a template for the first curved Trestle Bridge. It will be 3 inch's tall.
I am going to build a dock at the front of the layout, the piece at the front is the road into it.
A few more pictures of how it is taken shape
