Where Does All The Dirt Come From?

[Anonymous]

my grandfather always told me... "if two drops of oil looks about right. use ONLY ONE"

he almost NEVER used a dropper or oil tube/needle. he'd use a toothpick to transfer oil from the bottle/can to the wheel/axle or whatever it was he was oiling. so that he'd only be using a quarter-of-a-drop of oil or lube. too much oil allows more dust/dirt/etc. to stick in the wheel bearings and gears and can actually increase the friction. we found that switches/turnouts and bumps/imperfections in the rails were the dirtiest because of the shaking/vibration the train got as it crossed these bumps shook the crud onto the rails. we still had to clean the rails, but we probably only did it once a year. cleaning the wheels is as important as cleaning the tracks too. i remember seeing toy train cars that would ride tilted/crooked because of the gunk that stuck to the wheels and made a "tire" thick enough to make it ride high on one side[:D]

[dinner][dinner][(-D]Gee Dave all of this talk about hot dogs has made me hungry, so guess what I'm having for lunch.[swg]

Seriously, I like onions on my hot dog. Normally when I go to a sporting event, I put the onions on the dog first, then apply ketchup. When I go to the ball game on Wednesday, I'm going to try doing my condiments in reverse order, essentially using the ketchup to glue the onions to the dog, and keep them from falling in my lap.

The oil is what holds this mess to the track. Dust alone would simply fall off when the train went by. Any takers???[;)]

Elliot & Woodsy,

So what is the lesson? Oil sparingly? If oil and grease are applied sparingly, might this dirt phenomenon still occur?

I'm thinking that it might. Let's for a moment use the mustard/hot dog analogy. You get your dog, flip it in the bun, lay a thick bead of ketchup, then add just a teeny weeny bead of mustard. Murphy's law states that a bunch of that tiny bit of mustard will end up on your clean white shirt.

This was exactly what I was thinking, especially the CARBON, hence the black color. Add dust to the oily mix and you get that gunk or crud buildup on wheels and rollers. It can get so thick that it has to be scraped off, and can even cause derailments if allowed to build up too long. It sometimes comes off the wheels in chunks, and deposits itself in the frogs of turnouts.

The key ingredient has to be the oil, without that the crud would not collect and "snowball". (Just MY theory) [swg]

Could also be smoke fluid residue?

Or possibly residue from the cigars you are smoking?

Doug,

Unless you are using brass rails, oxidation shouldn't be too much of a problem (common, correct me if I'm wrong, folks). Dust devils are another cause of dirt. My dusty New Mexico desert scene has frequent dust storms that blow across the tracks. To keep the dust down, I use a spray bottle of water to wash down the trees and stuff, but not the tracks.

The fellow in the CTT May04 feature cleaned his tracks only once in 10 years; but he keeps a dust-free basement.

I didn't know the traction tires wear away. I have to check my Ballyhoo circus engine which I've run a million miles since Christmas. I've reused a lot of old track and some of the gunk seems to be simply oxidation. It rubs away with a bright boy eraser or ScotchBrite pad.

John K,

Good morning. I asked the same question once and some model railroaders told me that the seemingly never ending gunk comes from traction tires. Possibly when you use solvents on the rails, it interacts with the rubber and the rails and wheels of rolling stock get a heavy black coating. And, even if you didn't use solvents, I suspect the rubber just naturally coats the rails.

In the future, I plan to buy some plyobond and remove the traction tires on a test locomotive and put the plyobond on instead. I've heard from several folks who've done that and say that plyobond works better than traction tires. I suspect there will be less residue as well.

The traction tires in HO seem to be made of a different material (vinyl?) than our own dirty black rubber ones, and it doesn't leave as much residue.

To clean the track: NEVER USE SANDPAPER!!! it will scrape away your tin sheet fron the rail and rust will eat your tracks. From the european manufacturer ROCO you can get a rail cleaning gum, which works fabulous. Secondly, don't use engines with rubber bands around the wheels (extra traction). Those bands desintegrate in a year or two and they will smear themselves out across your layout.
Rubber is for cars, modeltrains don't have to have those. If they do, put in more weight.

From polutents in the air of course!
Especialy if you like to vaporize oil. [:)]

Get an air cleaner for the size of your room and use them track cleaners.
I've been having good luck with the new Lionel version.

Mineral Oil from smoke tends to condense on the rails of O gauge track, making them even more likely to get the crud on the track than other gauges. Track covered in mineral oil is a magnet for dust and dirt.

Why they make soft paint brushes. I live in 1940 built two story house and it is dusty. So you learn to dust keyboards, couple of fish mount trophies, wife's many menageries and other things with the paint bursh. It will work great on layouts too. After all, ever seen a clean railroad? [;)]

[Dr. John]

Just think, you get to BREATHE the same stuff that ends up on your track!

Seriously, I think your problem is common to all model railroaders of all scales. You get a combination of dust, moisture, oxidation and oily residue from the engines and cars. I find that the residue returns quickly, especially if you don't run trains. For me, emory cloth, Brite Boys and alcohol based cleaners do the best - emory cloth or Brite Boys for heavy duty crud and alcohol with a soft cloth for lighter jobs (the alcohol evaporates quickly without leaving its own residue). Wheel crud is a tougher challenge - you can scrape it off, or saturate a paper towel in alcohol, lay it across an unpowered stretch of track, and roll cars across it - helps some.

Frequent running of metal wheels on metal track helps keep the track cleaner longer.

I was doing a bit of overdue track cleaning (alcohol on a shop rag) when it occured to me that the three black streaks on the rag all looked the same size. Why was the center streak as big as the two outside streaks?

It must mean that most of the dirt was coming from the sparking, breaking down track, rollers, and wheels.

Anyone ever seen anything, or have some ideas, about the source of dirt on track and the crud that builds up in the flange corner of wheels. The crud builds up even on trucks on non-powered cars.
