Earlier this year, Märklin announced new larger curved points for the C track range. The points are made for both Märklin and Trix C track. Unfortunately, there was no drawing that showed how the geometry worked. This spawned a lot of guessing around the Internet. With the new Märklin and Trix catalogue hitting the streets, the guess work is over, because a drawing is now included.
Here are some drawings that show you how to correctly use the points with the existing geometry. I have used the same colours as in the catalogue.
