Gravitrax compatible ramp. Can be used in conjunction with the ball catcher. See my other designs.
Wet sanding the track helps to reduce friction.

Here's a video with most of the elements in my library. And... a preview of the lapse timer I am about to release. The lapse timer has custom electronics that I will be making in small batches. If you are interested in the lapse timer drop me a message. If there's enough interest, I could consider ordering larger batches of circuit boards and components.
