Trixbrix R40 Curved Switches
The curved switches from Trixbrix are fantastic and allow to fork or switch tracks on limited space. However, there is a drawback that comes with those switches: locos and cars easily derail when pulling from the peak to the outer curve of those switches. The reason is that these switches do not come with guard rails (check rails) on the outer track to prevent the axles from being pulled to the inner side of the curve, thus derailing on the frog.
Former Mattzobricks Core Development Team member Hilbert has created a small 3d printed part, that can be mounted on the switch and acts as a railguard to prevent those derailings.
The part designed for left R40 curved switches. For right curved switches, just mirror the part in your 3d slicer program before you print it.
Thank you, Hilbert.

If you want to convert a standard LEGO switches to meet the Trixbrix R40 geometry pattern, these instructions might help you.
This is what you need:
- Standard LEGO switch
- Standard corner (R72)
- A stable pad
- Some 2×4 plates
- Sharp knife, e.g. a utility knife

Please be aware of your fingers and handle with care!
Thank you Max for this contribution.
The easier version is of course to just order some R40 switches at Trixbrix.eu.
