Copied from my post today on RMweb:just started to file up the first of the rails and found that there was no sleeper under the central bend in the middle diamond.Hi John, That's correct to prototype for diamond-crossings 1:5 and shorter. This ensures that the diamond point tips can be fully supported on a timber each side of the centre. However, if you are not building with exact-scale flangeways in P4, S7, etc., the wider model flangeways mean that the diamond point tips will be further from the centre, and there is then room for a middle timber. Click the real > timbering > half-diamond timbering > timbering as model menu option to have Templot adopt this non-prototypical arrangement and include a middle timber. For more information about this, click the real > timbering > half-diamond timbering > ? half-diamond timbering - help menu item. This is the prototypical arrangement for a short crossing in P4 -- narrow flangeways, no middle timber: 2_270615_360000001.png  This is the non-prototypical model option in 00-BF -- wider flangeways, the diamond points are further from the centre, and there is room for a middle timber: 2_270615_350000000.png  regards, Martin. |
