... the shift shape corner 2 mouse action. It is easy to get the height correct -- just match the rails to the track gauge. Getting the length right is much more tricky. We need to match a switch to the green guide marks (bearing in mind that they were very approximate originally, and are now even more so). And also find a turnout length which matches the timber count (bearing in mind that we don't know the prototype or exact timber spacings, so again it is very approximate). gimp8.png Working in 4mm scale, after much trial and error I have matched the image to a turnout having a 12ft switch and 1:9 crossing angle. The blade tips and heel position (purple radial end mark) match well. The end-of-planing less so, confirming that it was very much a guess on the original. gimp9.png With the timbering added. For this size there are 32 timbers between the blade tips and the crossing vee. Which matches well my best attempt to count them in the original ...
