... exactly it is necessary to change to CLM unit angles and in most cases to generic V-crossings (it's not worth bothering to do this if you are not using an exact scale/gauge such as P4 or S7). This crossover then turned out to have 15ft straight switches and 1:10 V-crossings. The switch toes for the crossover then matched the switch location marks on the map. The accuracy of these 60"/mile maps is surprising -- the track gauge and 6ft way match exactly: 2_280402_310000001.png Having paid for a year's subscription to this NLS service I now need to get the next Templot update out quickly so that everyone can get a full year's benefit of it.
