I have finally got around to sorting out the track plan, It is based upon a single level plan that appeared in Model Railroader. It fits perfectly into my space and there is room for a helix up to the second level without exceeding the space I have avaliable. I have also decided to construct the layout in a domino style inspired by Mark Lestico and his Cascade Sub so If I have to move the layout I will not have to destroy it in the process. This is the outline of the bottom level at the moment with the upper level to come at a later date. The track plan will not be the same all around the bottom deck but will be similar. The loop up the helix to the top deck will be on the outside and the track down will be on the inside of the helix.
