... the B-6 turnout is much longer than it needs to be. Because of the contraflexure it can be shortened significantly -- here I made it a 9ft-switch 1:5 turnout, which still provides a radius of 1165mm (46"). Change to a curviform V-crossing, make a branch track, and insert an S-curve transition in it. Then adjust the length and position of the transition zone until the curve doesn't quite kiss the shed road, close to the end of it: 2_030829_590000000.png Then you can use the make transition function as shown in the above link to complete it. Because the control template is itself a transition curve, it is necessary to select its 1st radius in the make transition dialog. The shed road template can then be deleted and the new template extended to replace it: 2_030829_590000001.png I also normalized the first S-curve transition (to look neater on the trackpad, it doesn't affect the tracks). The fly in this ointment is that no prototype railway company ever used mathematical transition ...
