I get a lot of derailments at my EZ track switches, gray roadbed. Any help here?
It could be the cars, it could be the switchpoints, it could be the switch frogs. The question is way too generalized to answer well.
You need to do some detective work to analyze the problem and try to identify where these derailments are consistently happening. Is it the same car every time? It might be the car, with any of a multitude of issues associated. If it's not consistent with the same cars it might be the track. But where on the switch is the problem happening. Is it where the swiveling point rail touches the stock rail? Or is it where the two rails cross each other at an assembly called a frog? You need to watch it analytically and narrow things down before we can help you much. I will say that I'm pretty sure there are a few hundred videos on YouTube about this so you might peruse and see what comes up.
