Thanks for coming back to me guys.
Chimer, you assume correctly , both ends will be complete with no gaps, one is lower level and higher at the other end. Again yes, 3.5" over 8' which i worked out at 3.5%, locos have no issues but again this may change. The narrow base board along one side will be extended to match the 2' width the same as the other boards. The plan was to have a split level station at one end so upper over the lower level with some town scape, the sidings down one side a country station at the opposite end then maybe an engine depot, goods yard etc to come later.
Tony, mmm, looking at the layout I agree with you as regards to the stream line versus Hornby/set track but the only downside is having to fork out for the new points
