BaltACD Most common cause I would hear from trains stalling - "We were doing good until we got to the greaser."

Greasers also cause trouble going downgrade. The dynamic brakes cannot maintain as much braking force without sliding the wheels and the car brakes lose some of their effectiveness.
Just another complaint from an operator type.

DeggestyYes, the natural lubricants can be quite bothersome. You also do not want to meet a weed-killer train that has just come down a grade. It also makes the rails slippery. I still remember going up to Asheville from Hayne (just west of Spartanburg in the summer of 1964.
Used to get the Weed Spray Train on a regular basis in late May through the end of June up to about 2014 - the Weed Spray contractor switched from using a train to using a hi-rail vehicle - they could get more track time with the hi-rail than they could with the spray train.
Never too old to have a happy childhood!

Might do the job - especially if it blows the leaves off the tracks before they are mashed.
We'd have to get the shortline we run on to do the same with their locomotives.
I've found that under most circumstances, I can do just fine on clean, wet rail. That's why a pressure washer comes to mind. Add the leaves and it's another story. And the leaves tend to be like the rail greasers - their slipperiness gets spread.
Larry Resident Microferroequinologist (at least at my house) Everyone goes home; Safety begins with you My Opinion. Standard Disclaimers Apply. No Expiration Date Come ride the rails with me! There's one thing about humility - the moment you think you've got it, you've lost it...
Overmod But how quickly we appear to have forgotten the LaserTrain from the LIRR updates Dave Klepper provided -- and that doesn't seem to be flopping at all. (And who can argue with power lasers as a solution for anything??? )

Need to be tried out on Baldwin shark nose cabs first.

mudchickenThe idea is to lubricate the side of the top ball of rail (5/8" below gage corner on down the gage side of the ball), not the top.
That is gauge-corner and flange lubrication. TOR is a completely different animal (and a completely different set of salesmen touting different potential management-related bennies).
No few of the prospective systems for TOR point out not only that it needs to be applied only after the last axle of consist power, but that some means of either cleaning it off or letting it naturally degrade or be washed off the railhead region must happen before the next driving axle crosses it. Where this starts to get fun is in situations like climbing grades with too much effective train resistance, where a stalled train needs to back over its own dispensed TOR to get a better start. Various kinds of active rail 'washing' or passivation schemes are supposedly provided, and magically kept in full proportional working order with their precious magic fluids kept untainted and in full supply.
That TOR provides 'measurable' running resistance reduction has been demonstrated. I submit that the "market" has spoken much as MC has, that said reduction is not worth either the first cost or the ongoing maintenance to provide it.
I confess I had high hopes for the self-metering Crayola sticks on locomotives for flange and fillet greasing with hard compound that would not 'migrate' out to treads as easily. I also had high hopes for Porta's HAWP and for tools to maintain the various angles and areas of that profile. I'm still surprised at the general primitive state of many right-of-way greasers (a better term than 'flange greasers' in almost any circumstance) and how many areas are serviced by periodic MOW trucks -- one of the things I'm interested to see 'automated' as a sequel of the BNSF robot-inspection research.
mudchicken (Sounds like a job for a work train and guys with the knowledge of how to use fire hoze nozzles).....You might even get a few DOT 110 or 111 tank cars donated to the cause.

In the fall, on a breezy day, the application of this "lubricant" is constant. They'd just stick better to the wet rails.
I suspect that some sort of high pressure jet (as in pressure washers) would be more effective. Or a sand dispersal system that doubled up (or better) the amount of sand put down, to the point that it would overwhelm the leaves.
adkrr64Our RR has rail lubricators planted all along the right of way, and the lubricant is applied annually during the autumn season.
Plant-based and all-natural, to boot!

The idea is to lubricate the side of the top ball of rail (5/8" below gage corner on down the gage side of the ball), not the top. Being that putting the lubricant application system on the locomotive does not work (between the poor attention of the mechanical forces and the unthinking operationg people turning the applicators off (some are glorified wax crayons) , the things never work as intended), the lubricant is either put down by M/W hi-rail trucks or by wayside applicators.
Goop gage* anyone? The darned traction motors in the shiny operating toys (necessary evil things) create corrugation on the top of rail that only a rail grinder will remove in the end. If you start seeing "steel dandruff" along the gage side base of rail, you have serious i$$ues in your future.
(*) real term
Edit: 5 minutes after my reply, an article from one of the two railroad industry rags (PR) put out a set of articles on lubricants, lubricators and application methods (complete with the obligatory operating side whining)
I haven't read the article, probably won't as I don't subscribe, but I don't see any useful purpose to top of the rail lubrication. In fact TOR, as I know it, is a serious safety hazard!One day efforts to lubricate the edge of the rail head wound up leaving a very very small bead of oil on top of the rail. Needless to say that the division came to a complete stop on either side of the mountain because of lost traction.
.
Unfortunately, fillet lubrication ultimately turns into top of the rail lubrication on curves as the grease slings off of the wheel. This is then exacerbated by rain which will make the greasy spot spread along the top of the rail for a quarter mile or more!
Keep in mind that TOR and flange/fillet lubrication are very different things, involving different agents delivered in different ways.
IIRC, the top of rail lubrication would be done after the locomotives have passed.
Bob ThatcherI am confused - these seem contraditory goals.
And they are. OTOH, if rail lubrication is balanced with the need for traction, there's money to be saved. It also depends on the tightness of the curve.
Pay a visit to Deshler sometime (https://www.youtube.com/watch?v=b5eIj7-j0is} and listen to the singing as trains traverse the transfers (wyes), especially heavily loaded cars like coil cars.
If you can get close enough to the rails (without trespassing), you will actually see flakes of metal from the rails and the wheels on such curves...
Within the "Fighting Rail Wear" article in the February 2020 Trains, it was mentioned that "low friction hampers tractive effort and braking..." Later in the same article, the methods for lubricating the top of of the rail on curves (to reduce rail wear) are described.
