Hi SF Willie,
I'm a dealer for WS Products as well as a long time HO Model Railroader and forum member here and know the various difficulties that can arise in attempting to clean the rail with much of any scenery around the track.
After both, watching their video about this system as well as talking with Kevin at WS who demonstrated the products in the video I watched, I was very convinced that this system would be a great asset to both doing track maintenance as well as wheel cleaning of both Loco's and cars.
It seems to be quite well thought out and the pads can also be cleaned several times making them re-useable to last longer.
I really like the hand wand with it's flexable head for certain areas that might be hard to reach as long as scenery isn't in the way. It should also work well for reaching inside tunnels for the distance of the handle.
The cleaning wand comes with three each of four different pads, giving four varieties of coarseness for cleaning. Extra pads are available easily enough through me or others as well as extra Roto pad strip material when that becomes necessary.
The Loco wheel cleaning system would seem to have all other systems beat hands down as all wheels on the loco drivers are cleaned at the same time and for lead trucks, tenders or rolling stock it's just a matter of placing the car on the pads and rolling it back and forth a few times to clean the crud of the wheels.
I have the complete system on order less the dust monkeys for myself as well as another customer and should take delivery shortly. I feel WS has put a lot of thought into the product to ensure it works well!
I have all of these available and priced very reasonably. If I can get this for you or if you have other questions just let me know, ok?
Thanks for your inquiry, it's appreciated.
