... , the vee splice rail also has contraflexure. Sometimes this is what you want (in a curved crossover for example). But in many cases where the intention is for the tracks to diverge, it is better to change to a curviform V-crossing. Otherwise you will have a short section of reverse curve in the diverging road. Often this doesn't show very obviously on the screen, but it will do when looking along the finished tracks. To see what I mean, here I have greatly exaggerated the effect: 2_240554_100000000.png 2_240554_300000000.png I see this problem very often in uploaded track plans. I have tried to explain it so many times over the years that I'm not sure I have the strength to carry on. Templot can't automatically make this change when the curving radius goes negative because there are many cases where it would not be wanted -- in curved crossovers for example.
