... contraflexure). If that is part of a crossover, leave the V-crossing type as regular. Otherwise in many cases of contraflexure you will usually want to change to a curviform V-crossing. (A Y-turnout is unhanded, contraflexure turnouts are handed left and right.) More about types of V-crossing here: http://templot.com/martweb/gs_realtrack.htm#xing_types This is the result of the above in 4-SF (00-SF), with a curviform V-crossing: 2_080815_260000000.png That is such a short turnout that I suggest it is not what you want. Or if it is, the fact that you are modelling LPTB is irrelevant. To get a satisfactory result I used to the shortest 9ft straight switch. If you ease the crossing angle from 1:3.75 to say 1:4.5 you get something looking more reasonable, but at these angles you still need to use a short straight switch rather than an "A" switch: 2_080831_130000000.png In this case the turnout radius is now around 42 ...
