Lionel made a two-disc Track Cleaning item (6-36878), which is not motorized. Its two spinning discs may be a better track cleaning device than their one-disc version. However, I've heard that the two-disc model may be vulnerable to leaks of cleaning fluid from its onboard tank. I'm considering buying a 6-36878, but I don't want to buy a leaking product. Comments from hobbyists welcome.
