Well I'll contribute to thread drift.
You O scalers are hanging around with the wrong HO crowd.
I cleaned my whole HO layout after sitting for over six years during construction. Funny thing was, it still ran, but there were a few areas acting up. When I was running regular proto-op sessions , I didn't clean any track for over five years! I did track oil, and I'm going to try giving up on that, as I don't like the amount of gunk I seem to be accumulating on my rolling stock wheels (all of them metal). I'm planning on securing another two Centerline track cleaning cars for a consist of three cars), so that I can coat the first car roller with denatured alcohol, and the following two cars with dry rollers so soak up the deposits. When I track oiled, I applied light machine oil to the centerline roller pads.
I just got through changing couplers on 22 Proto 2000 freight cars from the crap Kadee knockoffs to Kadee #5s. At the same time, I cleaned the wheels. I was pulling off caked up dirt with my knife like chips on a lathe.
Instead of getting hollow wear in the thread, and high flange like the real thing, I get low flange from all the crap caked up on the tread.
I actually find that the HO works far better than three rail O from a track cleanliness standpoint (even discounting the poor DCS performance that will result from less than pristine track). Three rail has one big disadvantage. There are only rollers, with tiny contact patches for the center rail. Two rollers per locomotive, maybe four. Locomotive weight becomes inconsequential too, as the only force on the roller to the rail is from the spring.
When I was doing the modular gig, we ended up having to clean the track at least once a day, usually twice, or we started having engines acting up (yes, even running TMCC). The center rail was the big culprit, keep that clean, and life was good (as long as the TMCC signal didn't take a powder). We usually used cloth rags and denatured alcohol. Some of the guys like to use 600 grit emery paper, I was not a big fan unless the track (gargraves or Ross) rusted. Emery paper leaves micro scratches, and the dirt likes to accumulate in the scratches.
One of the best track cleaners I have found if you have to use a hand held device is a simple piece of 1/4" masonite (the shiny side). Good enough to clean just about any dirty track.
Two rail O scalers should have it far better that HO, but those who operate in HO learned the same tricks from O scalers; wipers on the backs of pickup wheels, and do everything we can for all wheel pickup. All of my brass steam are in the process of getting this upgrade, pc board strips on both sides of the driver, and phosphor bronze wiper wires on the back of the drivers.
With a couple of exceptions on switches that I still have not wired power to the insulated frogs, I simply do not have dead spots on my HO railroad.
I just did a three hour operating session, ran seven mainline trains, three locals, and the yard, and no reported dead spots, and only a couple of derailments in the yard ( ballast between the points and the stock rail).
I loved my time in O scale (albeit in three rail), but going back to HO has been a very pleasant experience, and the home HO railroad is far more reliable than three rail was on even its best day. And this is said not even factoring DCS into the equation.
This doesn't mean that I still don't long for doing a two rail O scale layout, but I doubt I will ever have the time, ambition, or funds to do that, and the HO gig too. A man has got to know his limitations.
Thanks for letting us hy-jack your thread George.
