... as look better) by following the prototype practice- or at least, there is no need to follow old modelling myths. Now I'm making a diamond and wonder about a similar issue at the centre of it, where the stock rail and check rail curve to form the angle of the obtuse crossing. It seems that on the prototype these rails curved quite gently- at least on the 1: 7.5 crossing I'm making. Someone on the Scalefour Forum sent a picture of a drawing for this area- here it is. 3591_091212_270000000.png The radius is marked, roughly track gauge, extending over a greater length than the sleeper width. Meanwhile the printout from my Templot template shows a curve, but not one as long and gentle as that, though it is difficult to say where it begins and ends- just the useful thing about the three marks on turnout acute crossings. 3591_091216_190000000.jpg Here is a screenshot of the Templot trackpad for the same thing, showing a crisp bend. 3591_091213_080000000.png So I'm wondering a few things about this. First, is there a ...
