... were not introduced until about 1925 and never used by the GWR. I think you could probably use the GWR loose-heel 12ft switches in the switch list if you don't have the dimensions to set up a full custom switch. First restore the geometry> turnout road exit length> normal setting. Next it is important to increase the crossing entry straight so that the turnout curve does not extend past the crossover mid-point. Use the SHIFT+ F11 mouse action to do that with the peg on CTRL-5: 2_050551_010000000.png Now, for a straight crossover: 1. CTRL+ F12 and reduce the exit track to the minimum. 2. either store it on the background and then geometry> shift/rotate> rotate 180 degrees. or tools> make mirror on peg, then template> swap hand: 2_050606_130000000.png On reflection it would have been better to extend the crossing entry straight even more, back to the wing rail joint. Do you have any prototype drawings for this? I seem to remember it was all in an early issue ...
