So they look for a surface coating or cleaner that reduces micro-arcing
(if that really is the main reason) but doesn\'t affect traction too
much; anhydrous isopropyl is thought inappropriate because it leaves the
rail surface too dry after it evaporates, some swear by mineral spirits,
I guess some use a thin coating of automatic transmission fluid.

Is it possible to rather reduce the micro-arcing at the source through
some kind of snubbing or is that not really feasible wrt the process
described.

As a kid I did something nasty. *Don\'t* try that at home.

I modulated high voltage spikes onto the voltage that went to the rails,
similar to electric fence pulses. No more problems with locomotives not
starting up or stalling. The pulses were strong enough to burn through
any dirt layer. Of course, listening to the AM band was, ahem, slightly
compromised.

They are no different from your Tesla - it doesn\'t charge while you\'re driving, either.
Your reading comprehension is pretty poor, eh? That is in no way responsive to what I was saying.

Mine is fine, but yours SUCKS! Go reread the material - it is all in there.
Flyguy is great at reading material and deciding that it says exactly what he wants it to say.

He\'s got excellent self-indulgent reading comprehension. He\'s less good at comprehending what the text actually says. I\'ve been noticing this for a few months now.

https://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect

If you are too dim to comprehend what the text is actually saying, you can be dim enough to think it supports your point of view, even when it doesn\'t.

The ONLY thing Sloman is great at is SNIPPING! He clearly can\'t read, either.

It\'s clear that Flyguy resents having his defects pointed out. Flyguy is correct to assert that I can\'t read the stuff he links to as supporting his moronic assertions. Nobody with functional reading comprehension could. His \"reading comprehension\" is the kind that skips over the text finding the bits he likes and ignoring the bits he doesn\'t like, and he\'s too dim to realise what he is doing.

Yeah, I would expect your local radio-controlling governmental body
would get a little upset at an unlicensed transmitter on the airwaves

Well, I was only a kid

The noise wasn\'t worse than that from electric fences though.
