I set the radius of the main line and minimum radius of 1200mm warning. In the information panel I get the switch and turnout curve radii and also a smallest radius on template figure. What does this last figure refer to? Hi Graham, Welcome to Templot Club. Here's a diagram for a turnout with a regular type V-crossing: 2_260807_370000000.png The smallest radius now figure shows whichever of these radii is the smallest. According to the various turnout settings, and the main road curving, it could be any of them. However, the switch radius is not usually smaller than the turnout radius. In some turnout sizes, called natural turnouts, it is the same as the turnout radius. These sizes are A-7, B-8, C-10... Here is a case where the smallest radius is in the main road. This might ...
