Has anyone any comments on the effectiveness or otherwise of the above attachment, particularly on R1/R2 curves?
I no longer use mine.
Honestly and briefly, they dont seem effective, although, theoretically , they must be.
They might keep track clean, once properly and thoroughly cleaned some other way, and then only if used daily, and with repeat passes. Obviously, you must always run the car with pads, which also gets a bit tiresome, unless you fit multiples. The small pads become tattered fairly quickly, and also become saturated with brass oxide dust rahter quickly too, so they must be cleaned (with something like the LGB smoke fluid) or replaced.
They tend to hang up, on joints, frogs and the like, less so when fitted to a car, like a flat or gondola, with a good deal of heft to keep the pads down, and to force them over odd edges , mis-alignment, etc. They work fine on R1, provided you have fitted them a car with the shortest wheelbase-ie 2 axel, no brake platform.
For what they cost, id suggest giving them a go, and seeing how they work for you.
if you can afford one, the track clenaing loco is superb, fun, easy to use, and worth its weight in gold on long railways.
Better still, albeit far more effort, and less fun, is the red cleaning block. It is imho, simply unbeatable for getting every spot clean.
I use both.
If funds are an issue, id spend on the red block before the undercarriage cleaning pads.
i have a rolling frame, into which fits a red cleaning block, which floats in the frame, and it is pushed or dragged, doing much the same as the carriage pad system, but with far more surface area. While marginally better, when add a 5 lb lead ingot on top of the red block for more abrasion, it must then be pulled or pushed by at least 2 or 3 stainz, an alco, a mallet, ,etc due to huge drag. It too has issues hanging up on joints and tracking with such weight on top should there be a slight twist in a curve.
My point being, the only gadget I've used that works really well, is the track cleaning loco. Should you decide to go this way, there are previous threads, with tips. Im happy to give my thoughts on tips for the loco should you ask.
