... quite a lot of data for USA standard-gauge, but not for narrow-gauge. 2. a Fast Tracks template? Do you know what data it is based on? 3. a turnout constructed in a Fast Tracks jig? Those are likely to be 3 different things. If it is a ready-built turnout, your best option may be to turn it upside down and scan the rails directly as a picture shape. Looking at your posted picture shape, which I assume is a Fast Tracks template: 2_291123_210000000.png The turnout curve appears to have been drawn tangential to the exit road at a location approximately at the end of the wing rail. Hence it appears to be a larger radius than can physically be fitted between the switch and the intersection point. In other words it is drawn as a curviform V-crossing as far as that location, with a crossing angle of around 1:7. If you wanted to replicate that exactly it would be necessary to use partial templates (I'm not aware of any such prototypes). ...
