As the title suggests, feel free to discuss/share your stories/experiences with locomotive wheelslip.
Or Webm's/Gifs/Links.
That is fine too.
Also, this is not limited to only steam, but diesel-electrics as well, as such is usually the first thing to come into mind upon wheelslip.
What do you want to know about wheel slip? It's normally an environmental thing (slick rail) or fault with a traction motor these days. The solution is to blow sand, apply a slight amount of independent, or cut out traction motors sequentially until you find the faulty one. It's not that impressive since modern locomotives will inform you of it in the cab and you can quickly correct it.
Still doesn't stop some morons from burning up rail and creating a lot of work for a bucket gang.

Oh, I should have been a bit more specific when I stated that, heh.
I know all there is to know about wheelslip, this were just for others to discuss, like what went wrong, what the crew did wrong if referring to steam locomotives, etc...
For example, the Blue Peter Slip of '94.
What exactly happened to the operator, as it were stated the he broke both of his arms in an effort to stop the violent spin thanks to a valve that were forced wide open by steam pressure.

"In 1994, during the first run of a preserved steam locomotive from Edinburgh to Newcastle, 60532 suffered extensive damage during a catastrophic uncontrolled wheelslip"."During an unscheduled stop at Durham Station the inexperienced footplate crew overfilled the boiler. As the train departed south across Durham viaduct an initial slip was poorly controlled by the driver, who then reopened the regulator too early, probably worried about stalling on the bank up to Relly Mill. The force of the initial slip caused the boiler to prime, carrying water over into the regulator valve and jamming it open. This allowed passage of steam through to the cylinders, perpetuating the slip and accelerating the driving wheels. When the driver attempted to wind the reversing gear back into mid-position to halt the slip, the force of the boiler spun it into full-forward position, and the driving wheels reached a rotational speed of 140 mph before the cylinder heads blew off and the motion disintegrated.
The driver suffered major injury to his arms, as a result of the screw reversing lever whipping around when he released it. The accident brought to light the importance of train crews being trained on the specific locomotives they were driving, rather than simply a common general instruction on steam locomotives. Neither the driver or fireman had ever worked 60532 before, and were unaware of the locomotive's sensitivity to priming, which led to the accident."

I see.
From what I observed from the video as well as your explanation, one could say that both the driver and fireman were at fault, but somewhat "poor" maintenance were to blame, no?
>>938126
I've got no idea, but from reading boiler priming is related to operator fault, design and poor water. Maintenance doesn't seem to factor in, and with the amount of work that goes into getting a locomotive a boiler ticket I doubt it would in this instance.

Another thing I do not understand is why both railfans and "foamers" alike get off to experiencing wheelslip.
As you stated, it is really not as impressive on modern day diesel-electric locomotive as it is on a steamer.
I can assume that slipping with steam engines occur more often in the UK than in the US, due to the latter having a nearly balanced dome throttle, unlike the former.
>>938137
>balanced dome throttle
Forgot to ask, what's that mean?
>>938176
Because steam engines don't work like diesels, bruh.
>>938177
In general, in the steam dome is a valve which basically is what the throttle/regulator opens/closes on a steam engine, thus controlling thus supply of steam to the cylinders.
While in the US, the domes are rather cylindrical in shape, from what I have seen, domes on the UK are more "cone" shaped.
I forget really.

What they said.

Relatively, as opposed to, say, 1800s.

You'll have to be specific.
What exactly is it that you wish to see?
>>938603
I like videos that describe how either the operations or how the actual locomotive work in more detail than you usually see on shows nowadays.
If that's too picky then maybe one of your favorite vids?
Don't worry too much about it, the ones you posted were great.
>>938639
https://www.youtube.com/watch?v=M4BWsYbJROQ
Hm, you're fine, but still reasonable.
I had quite a few in mind actually.

This.
https://www.youtube.com/watch?v=rYw5MmJH-uw
This I suppose.

And to stay on topic with the thread.
It would be nice if more people were to contribute though, as it really just feels one-sided in my opinion.
>>938662
>one-sided in my opinion.
It's all good. You're not really offering some kind of argument. I'll check those vids out later tonight I hope.
Give the thread some time while other anons sift through it and there's bound to be more questions/comments etc
This engine is very prone to slipping, as it was originally a tank engine. As a tender engine, there's less adhesive weight. Of course, it's much more fun in this form anyway! We're considering attaching heavy metal plates to make it less slippy.
>>938662
Ok, I got to watch those vids and that's what I'm looking for for the most part.
The two amateur walkthroughs I couldn't even finish watching because reasons that irritated me.
Regardless, thank you. And the last vid with the wheelslip was great.

I actually have a 2-disc collection upon various documentaries abut the railroad, its history and whatnot from Walmart for a steal of five dollars.
It probably covers what you are looking for as well.

Is this what you asking for?
>>939288
More or less.
The only reason I have been posting mainly wheelslip from steam locomotive was because I simply figured that was what most people would think about.
Oh how I was wrong, kek.
I have seen some ridiculous wheelslip/wheelspins on diesels as well however.
https://www.youtube.com/watch?v=-5E6lrkpp9Q
Like this.
>>939297
Someone definitely should montage Hulk Hogan's theme to this video.
>>939297
How is that happening/allowed?
I thought those were computer controlled to not do that.
>>939311
https://www.youtube.com/watch?v=G9qTWEjG-Qc
To be frank, i'm not quite sure.
I assume that most of not all locomotives built from the 80's back did not have such technology, going off from the general shape of such, as it is rather dark.
I assume it is of the EMD four-axle "General Purpose series, or GP.
>>939321
That vid reminded me of when I drive in the snow and how I have to use smart throttle application since I don't have traction control. It's actually really fun and rewarding.

It will tell you the slip is happening. It's up to the engineer to do something about it.
Wheel slip happens quite a bit when you're switching and working industries.
>>939726
Ah.
So I was way out of the ballpark with my answer.

What the flying fuck? Surely the engineer must know he's fucking shit up and not going anywhere. Wouldn't blowing sparks like that clue you in that keeping on the throttle is futile?
>>944743
Either they SOMEHOW didn't notice, even then the notices are practically screaming in front of their faces, or they just didn't care.

2 Class 56's struggling
Funny how 1 class 60 could've managed this without a sweat
>>945201
I suspect it's referring to field weakening on the (DC) traction motors: https://en.wikipedia.org/wiki/Brushed_DC_electric_motor#Field_weakening
Class 56's have an alternator (so an AC generator) but then it's rectified to old fashioned DC traction motors, and there's a fairly sophisticated control system/computer to manage it all.
>>945217
Awesome, thanks anon.

do you know any good book titles or authors about railraods and the technical stuff of railway constriction?

All I can really say is that you have to go out and search for yourself.
From what I have seen on the Barnes & Noble Bookstore's website, the only one which be be of interest is this:

Would love to see one like op's where the conrods fly off and shit seizes and flies everywhere.
If I had the money I'd put cameras everywhere and fully surround a loco with protection while I'll jam that sucker WOT while being held stationary.
