The check rails and gap that should be produced at the point where the two half diamonds would meet are not generated. In the attached box file the two lower sets of track are from a 1:9 regular and generic turnout and have not produced the check rails, whereas the top one is 1:8 and has. 32_151949_370000000.png Attachment: attach_1446_1960_DiamondCrossings .box 301 Last edited on 16 May 2012 00:53 by Andrew Fendick posted: 16 May 2012 01:00 from: Martin Wynne Hi Andrew, Fixed K-crossings are not prototypically correct at angles flatter than 1:8, and would be extremely unreliable if modelled as such. Switch-diamonds (movable K-crossings) are used instead, and Templot draws them as such, like this: fb_movablek_dslip.jpg© thanks to Mick Nicholson An excellent picture from Mick Nicholson showing a flat-bottom double ...
