I've got a centerline. She works nicely over plain rail and lionel switches with a half load of BBs in the roller tube.
If I wanted to go crazy and make it look ugly one could install a drip oiler{habor freight} over the roller, via a bracket, to get big layouts...I run a carpet empire so that's not needed- for me at least.
I need to pop over to Ace hardware for some e-clips for my 2 rehabbed lionel cars{darn oem clips break when I recrimp them}....I'll see if they have any roller stock there that works in this cleaner.
Oh, the oem rollers that come with a centerline cleaner look like they're paper rolls inside- the replacement rollers centerline sells are said to be waterproof- I doubt the "1st set" that comes with it are though....input on that from those who've tried?
