... in the desired place it's unlikely that you will be able physically to fit the tracks there. In answer to that question I've now, at last, done a screen shot of the problem that I experienced when using "Peg\ Align\ Make transition curve...". In fact I've done 2 screen shots one of the initial result as proposed by Templot and a second with my change to the curve to make it "match/ align". 2787_021620_120000000.png And this is what I modified it to... 2787_021617_010000000.png I used F6 to change the curve to this which I think looks ok, but without scanning along the curve with my eye down at track level I don't have any means of knowing if I've created a dogleg in this curve. Have I done this the correct way or do you have much better way of achieving a smooth transition?
