<{POST_SNAPBACK}>Therefore your comment only applies to GFN Profi turnouts and no others?
However, the important dimension is the crossing gap and whether it is moving or not, it will cause stock to lurch, if it is excessive.
Correct - (although I am assuming "GFN" is a typo) & the movable frog is only a feature of the express points.
If you look at the FLM express points you will see that there is no gap, due to the moveable section of the point.
Also, in our experience FLM Profi track is far more "universal" than another well known make that used to call it's track "universal".
It's beginning to get to the situation that you either have to compromise & accept the odd "lurching" with finer scale flanges using "universal" track or use a much finer track & change all the wheels.
