Question for Joe

Very good article on track cleaning cars ...

A question — these systems basically clean the top of the rails. If I understand Joe, where the electrical contact occurs is at the edge of the top of the rail — that it is most important to clean that edge, not the top. Is that correct?If so is there a car designed to do that?

Cleaning Rail

Jimcubie1 makes a valid point, and maybe the ultimate solution is to make model rail more closely resemble prototype rail.

The standard rail profiles have a curved top surface.  Under traffic it gets crushed and worn to a flatter surface; railroads invest significant amounts of money to grind it back to close to the original shape.  The design goal is to have the wheel treads follow a fairly narrow contact band as this can then be used to help guide the wheels and reduce flange wear.

This narrow contact band on the prototype is what we are after on our model wheel/rail interface.  With a narrow band we should be able to sweep is clean with any of these "slider" cars.  As it is now the contact is close to the gauge corner/flange throat as Jimcubie reports.

Good question

Good question, now I have to go read the article.

Soft cloth track cleaning cars best

Abrasive or masonite slider track cleaning cars get the top inner edge, but it’s true the lower inner edge can still have oxides. But every little bit helps, so these slider track cleaner cars remain popular, but they’re not ideal.

BEST TRACK CLEANING CARS
The best track cleaning cars use a cloth with solvents like mineral spirits. The heavy brass CMX Cleaner tank car is an excellent choice. It has a spring loaded corduroy type cloth wiper that gets soaked by a regular drip feed from the tank car. The spring loaded cloth wiper gets the inside railhead as well when cleaning.

However, the CMX car alone isn’t enough, otherwise you’re just loosening and redistributing the black gunk and not really removing it. Loosening the black gunk does expose some fresh metal on the railhead, so it is helpful, but your track will crud up more quickly again and you’ve also loosened black gunk to be picked up by rolling stock wheels depending on how much you have plastic wheels (more prone to accumulating loosened black gunk) vs metal wheels (less prone to accumulating loosened black gunk, but not impervious).

To pick up the loosened black gunk, you need one or more Centerline roller cars to follow behind. These cars have a heavy brass roller wrapped in a handy wipe like material. The soft loops in the cloth on the roller also seat down around the railhead, cleaning the top inside railhead as well. The La Mesa club runs THREE Centerline cars behind the CMX tank car with the solvent-soaked pad to pickup the loosened black gunk. Just leave the handy wipe cloth on the roller dry, don’t add any solvent.

TRACK CLEANING BY HAND STILL BEST
While a CMX car with mineral spirits followed by one or more Centerline roller cars is ideal, the best track cleaning will still be using a robust Q-tip soaked in mineral spirits rubbed along the top inner railhead until no more black gunk comes up. I like to use gun cleaning Q-tips because they’re quite robust and gave a longer wood handle that helps when trying to clean under bridges and inside tunnel entrances.

I soak the cotton bud in mineral spirits and work on six inches of track at a time, focusing on one railhead at a time. I rub cotton bud along the top inside railhead, making several passes, rotating the head slightly with each pass to expose clean cotton to the railhead. If the rail is especially dirty, it can take a couple Q-tips to get most of the black gunk.

To finish up, I rub a dry Q-tip along the inside railhead as well, rotating it and making several passes to make sure I’ve gotten as much black gunk as possible. Then I move across to the opposite inner railhead and repeat the process.

APPLYING GRAPHITE AFTER CLEANING
Once I’ve cleaned both railheads like this, I come back with a 4B stick of graphite and using moderate pressure give the inner railhead one quick swipe of graphite. I do not rub it back and forth nor do I give it more than one quick pass.

Lately when I clean like this, I have started apply the graphite in short 1 foot sections and the skipping a couple feet and applying another foot of graphite with a quick single swipe. I especially like doing the every foot then skip a couple feet method on grades to make sure I don’t overdo the graphite application. Graphite is something you must be very careful to not overdo because MORE is not better. With graphite, it’s the extremely light coat that you can’t see that does the magic.

DID THIS ANSWER YOUR QUESTION?
Hopefully, that answers your questions. We have a TMTV video coming soon where I demonstrate my track cleaning and graphite application methods.

My favorite cleaner remains this self propelled DCC powered vacuum and scrubber car from Korea Brass:

1_123554.jpg 

It's not made in brass but the company that makes it primarily works in brass.  I learned about this car from Model Railroad News and when my personal Fallout Money ahem Selective Reenlistment Bonus dropped, I cleared my wish lists and this was on it.  I had just enough time to run it around the club layout one lap before shipping off to Korea for the second time. There, I had the immense pleasure to meet the man who designed and produced this machine; he graciously gave me a tour of his factory and showed me the 3D printed prototype used to develop the diecast body.

In the vacuum hopper there are again the results of a single pass around the club layout.

1_123650.jpg 

But wait, there's more!  In addition to the vacuum, this machine also has a set of magnets and not pictured after this, a scrubber pad.

1_123915.jpg 

The only issues noted during testing was the fact that scrubber pad does not like going in reverse through turnouts whereas the felt covered sled is at an angle.  There is a second issue whereas the couplers have been designed to coupe with blueprint coupler height and not the Kadee standard, whereas Korea Brass designs all of their models to have the coupler centered at standard blueprint coupler height, if that makes sense, which puts is about 1/16"-1/8" higher than the Kadee height.  An underset coupler solves this issue.

My unit has not had enough track time for what it is worth, but it's a beautiful machine.  As if it could get any worse, I now own two because you can get it in yellow with a green roof or green with a yellow roof and I wanted a yellow unit and a green unit, even if I eventually repaint the cars and roofs elsewise.

(Alas, it appears this model has been downgraded and then discontinued.  If you find one at a decent price ($250), I would consider it.)

KB track cleaning car...

Is the Korea Brass car still available?  It seems to have been removed from their web site.

Randy, it appears on Kore

Randy, it appears on Kore Brass's site, but it appears their US outlet is no longer carrying it.  It may have been discontinued.  I also notice they dropped the DCC option and went to just a DC option that is perhaps DCC ready.

Ken did review it on What's Neat in 2018.

In watching the video, I forgot that it is indeed self propelled.
