Hi
Have given it a try with an IM FP7. Kato F7, Atlas FM 15-44, and a Life Like SW9, with NWSL low profile, replacement wheel sets. All worked in DCC with the exception of the SW9, the flanges are too small to make contact with the power strips. The cleaning effectiveness with light to moderate wheel grime was not so good. I still had lots of dirt on the wheels after using the Tidy Track, then using my tried and true paper towel over the track saturated with a bit of Goo Gone got the dirt off. I also tried to use the scrubbing pads, which appear to be thin strips of velcro hook or loop , I am not sure which. I did not see any contact between the wheel tread and the scrubbing pad. When I get a chance I am going to try Goo Gone and denatured alcohol or the WS track cleaning fluid (not at the same time) and see if this improves the cleaning action. I really want to use this gadget- it is well designed, either working on track contact, or a set of alligator clips to supply track power. The cleaning strips are easy to change, and it seems like a high quality product. I have purchased the rest of the WS Tidy track system, and am happy to report that the track cleaner works well, the attachable extension rod really gets the cleaner into hard to reach areas, and the little dust monkeys work well to continually dust off the track as you run trains.
