Did some testing and suggested to Rokuhan that R120 was too small for most of the existing Z scale locos and cars and that R145 might be better received. Word has come back that this project has been upgraded with R145 radius track and the case size is a bit bigger at 70 x 70cm while height remains the same. The new smaller switch should be available to go with this layout and a new smaller controller which can be mounted inside the case.
