Dallas,
Figure a lot of us are reaching the 'checkout' age so we need to, at least, make an 'inventory'.
=====================
New delivery.
CMX track cleaning car.
These things are expensive so it took awhile until I finally won a bid that was under 100 bucks (92 plus shipping, etc 109 delivered).
It's all brass so it's heavy. This is a used item. Came with trucks and couplers.
Suppose to adjust the two knobs on top to get a desired flow of liquid.
The two wires at each end snap over the brass bed to hold the cleaning material to the pad.
I ran the car with a Bachmann PRR GG-1 (my 'work train' and 'mainline tester' engine). I changed between 2 pieces of cloth about every 100' and then every 200'. After about 3 or 4 trips and about 1000' of track, the rail is very clean as, using a paper towel, it was clean after wiping the towel on the rail. I'm very impressed with this 'track cleaner'.
I used lacquer thinner as it removed 'gunk' quickly but evaporates quickly and leaves no residue.
The pads only get dirty along the rails and they got 'gunked' pretty fast so I just soaked one while using the other.
I found it easier to just soak the cloth versus using the knobs to adjust the flow of any liquid.
One gets about 2' of cleaning cloth that can be purchased separately. I thought I'd try some felt but the surface is too coarse and doesn't work well.
My old track cleaner can be retired after only 45 years. I believe it's by Ulrich from the 70's.
New truck bed soft cover installed after the old one got destroyed by the high winds when taking the grandkids 3-rail layout to their house. My 17 year old Chevy Silverado truck with only 200,000 miles and no rust and the best part: 325 CI V-8
Of course, under the hood has to, also, be kept super clean:
