Mark or Dom (or anyone else using Aztec track cleaning cars) ... what is the minimum radius you can use this car on? I see on the Aztec site they say 7.75" which is an R195mm. But, can they work down to R145mm curves?

I haven't specifically tried R145 (I can tomorrow), but it's basically an MTL 40' boxcar and I've run those down to R120mm.

Hmm. John at Aztec contacted me and expressed concern with how the pads are applying pressure on such tight radii.
The question I had was borne out of one of his customers saying it didn't work on a Noch layout (how I came into this discussion). Seems to me that it should be able to RUN on tighter radii such as 145 or 120 (as should any MTL box car), but that the effectiveness of the cleaning may be diminished.

Today is a travel day for me, but I'll check it tomorrow and try to shoot some images.

I keep my layout covered with one of those light-weight space blankets. No lint from cloth & so light that it doesn't disturb the scenery.

The main purpose of the Aztec car is to polish the oxide off the railhead to improve electrical conductivity. Unfortunately I don't know of any cover that will stop oxidation, but the car cleans it off really well. Mark

On my current layout no curve is less as 14" / 35 cm radius. Best to wait data from Aztectrains' brass. Dom

Unfortunately she removes all the oxygen from the room.

Having worked on this sort of problem professionally, I think you're setting yourself up for an impossible task. You'll have an out-gassing issue with the layout materials, no to mention the room itself. People talk about using an anti-oxidant liquid or paste to protect the rails. I've questioned the value of these as sooner or later they'll flow into the ballast and the electrical arc through them will cause a potentially damaging chemical reaction. The cleaning cars, like Aztec seem to be the easiest and fastest solution. Mark

Mark, you are correct about the topical application of any liquid other than alcohol. I am familiar with only one gas used to prevent tarnish ...on silver. Cake camphor sublimates directly into a gaseous phase without becoming liquid. The cover described by Deb, or maybe a tunnel enclosure, would serve to retain that gas (and also retain the camphor smell.) Aztec (or other) does smell much better. Rory
