To fix it without changing your other alignments I used a 9ft-5.6 turnout. Although very short, the contraflexure means the radii remain well within your limits. With a bit more tweaking it could be changed to a more likely prototype 1:5.5 angle. Or with more tweaking to a B-6. 2_200955_080000000.png You have made very little use of transition curves, which gives the design a bit of a train-set look. Also there was a mismatch at the top right. To show what I mean I have introduced 3 transitions (marked yellow bars). You can see that it produces a better "flow" effect -- and also smoother running. .box file below (no other changes). regards, Martin.
