Hi Geoff,

I have imported the NLS 60" map as a background:




I notice some differences between the map and your plan:




At A the alignment and switch positions differ. At B the original curving is sharper than your design.

I used the georeferenced version of the map. Did you use a different version of the map, or maybe the original single sheet version? Georeferencing does change the curvature. Or maybe some other railway map or track plan? Or are the differences intentional?

You referred to a tandem turnout, but I'm not really seeing that. What I'm seeing is an outside slip. It doesn't necessarily make any difference to the final result, but it might change the approach to creating the design.

cheers,

Martin.
