... I need to work out which bits of rail need to be (electrically) bonded to each other, and which bits need to be switched (and hence isolated). The rules are the same as for all track formations -- all V-crossings need to be isolated from the surrounding rails and have their polarity switched. K-crossings do not need to be isolated or switched. In the case of a slip, single or double, the V-crossings are switched by the points at the opposite end: 2_221250_560000000.png I've just noticed that one of the turnouts that leads into the DS is shown as having too tighter radius, so I need to straighten that out a bit. Is there any easy way of reattaching the other templates to it afterwards (assuming the geometry works out) Yes, use the group notch linking functions. If you post your .box file here I can explain properly. regards, Martin. posted: 23 Mar 2014 15:04 from: Adrian (ffoil) Martin Wynne wrote: For a neat result in ...
