Ed, thanks for the tip, I will go ahead and bevel the rerailers where you indicate. I wash the fabric after each use and when it appears to be worn out, I will cut another piece off the roll that came with the car.
Mel, I appreciate the offer but I do not think that kind of effort on your part is necessary.
Bear "It's all about having fun."
I have several wood plank crossings and some are styrene. I bevel the approaches to reduce the chance of any "dragging equipment" getting snagged on them, including the fabric of the CMX cleaning pad.
I don't have any plastic rerailers but if I recall, they come to a point. You should bevel the leading edges of these points.

Bevel the edges I've highlighted here, especially that point:

Run the CMX over the rerailer by hand until you don't feel any snags anymore. A little resistance over the "Planking" shouldn't cause a problem.
Be sure your cleaning pad is replaced often and that it is clipped so that it is snug against the brass backing plate.
Good Luck, Ed
Does anyone have issues running a CMX cleaning car over a rerailer track? And how did you solve it? Sanding down the middle brown portion of the track?
