... Hi Robert, There are several possible solutions, but the simplest is two transition curve templates: 2_261703_520000001.png These have a common radius of about 1315mm at the centre, reducing to about 1120mm radius at the outer ends. I created them using the "make transition" function, described in this tutorial: http://www.templot.com/martweb/info_files/make_trans.htm First I did tools> make branch track on the turnout templates. Then I positioned a dummy template (blue) outside of them using the F10 swell mouse action: 2_261703_510000000.png Then use "make transition" to the dummy template to create each transition curve template. It needs a bit of fiddling about with the radii -- the curves must come as close together as possible without actually touching, and they must do it at locations well clear of the centre section, and clear of the turnouts. Otherwise the resulting transition zones will be too long and/or overlap each other or the turnouts. If you have not used "make transition" before you will probably need a bit of practice ...
