... That is very rarely found on the prototype, except perhaps in cramped yards. Apart from looking unprototypical it can also cause rough running and sometimes overthrow and coupling problems. Reverse curves always have a length of straight between them, or else they transition smoothly from one direction to the other in an S-curve. Generally in models we never have enough space, so inserting a length of straight between reverse curves isn't always feasible. But Templot makes it easy to create smooth S-curve transitions in place of reverse curves: 2_292139_340000000.png Here I have used Templot's make transition function to create a sweeping S-curve transition between your curves at A and B. You can see what I meant by a less geometric and more flowing design. Now we can create another transition for the other running line, and start inserting the pointwork into the curves: 2_292143_000000000.png I changed some of your turnouts to C-10 size. That is always a good size to use if you have room for them when creating curved pointwork, allowing easier radii than shorter curved turnouts ...
