... -turnout is symmetrical, and b) the V-rails are straight beyond the fine- point intersection, then yes, the divergence is 1 in 10 each way. Approximately -- to be strictly 1 in 10 RAM each way the Y-turnout needs to be 1 in 4.95 RAM, not 1 in 5 RAM. Note that for the V-rails to be straight you need to use partial templates as in my previous diagram, or alternatively insert a zero-length transition at the fine point like this: 2_061452_060000000.png I think you are asking about the radius of the turnouts. You want a Y-turnout having approximately the same radius in each road as the turnout radius of an A-5 turnout? That raises the question of which radius to use. I suggest you use the internal geometrical radius, which is the same for all 1:5 crossings and independent of the type of crossing and the type of switch. You can find the internal geometrical radius by expanding the info panel and scrolling to the bottom. You will ...
