Track Cleaning Cars?

Anyone have a recommendation on a track cleaning car? I’m thinking one that can operate wet is the way to go. I’m not only concerned about effectiveness, but also derailing.
Thanks,
Mark

Go to www.centerline-products.com and see their entensive-expensive line of cleaners. Unfortunately
you can’t get them at a good discount.

A small block of masonite (rough side down) with some weight,mounted to a box car with Evergreen styrene telescoping tubing works well, and doesn’t create too much drag.
