Metaal opstuwing in dutch (dont know the correct english term), metal cluttering?
The stuck brakes probably happened somewhere along the way from germany to rotterdam (i guess maybe like 30 miles from the waalhaven, rotterdam). If it happenned from its starting point sensors along the route would have picked it up + another opposite driving train driver would have seen a lot of smoke coming from the train..
The cast iron brakes always get this terracotta color like pattorn when they get really hot.

1 + Just because you are from The Netherlands

Also here we no longer use (class 1 railways) castiron, brake shoes. We switch them to low friction composition brake shoes.

As a Freight Conductor we call that Slag Build-up. And yes it will derail a train if it gets bad enough.

Now THIS is Braking News!

Braking bad.

In Canada and USA, its called built up therad. 1/8 build up (according to AAR) is usually grounds for changing the wheel.

Shit better stop leaving pennies on the tracks

@op that is called tread buildup (TBU) or treading in engels :)

I'm soooo glad that wasn't an animal like I originally thought it was...

I’ve seen wheels come in glowing blue but never this.

I thought you ran over a bird.

Thought it was a dead bird under there for a second.

For a truck, you spray the heck out of it with W-D 40, then smack it with a Ball Peen hammer.
kban72
Its fun to say Ball Peen Hammer.

So the excess metal comes from the rails, right? Not the wheels?
wrinklegrommet
What does that all mean in terms of repairs/replacement?
nojustsayitdont
About $3.50

In the States, it can be built up to a certain height before the wheel has to be changed
BelarusianPotatoFarmer
I think the translation for the technical term would be "metal catch". We see the same thing in automotive brakes.
intashu
Brake pads and wheel need to be replaced from heat hardening or just clean the slag and go.
TheFeralDog
Brake shoe yes, wheel depends on damage a carmen will come inspection and measure the wheel for damage. If it's within legal specs it stays

Friction braking, what a waste. Wonder when 99% of trains will be electric, so the engine can regen brake w/as much power as it launches.
MacClay
For that to work, every axle would have to be powered, and convincing train companies to pay for that is going to be super fun.
TheZui
Most trains I know of (europe/germany) have regenerative brakes. But they are not as effective as the air brakes.
onefaller
trains are electric. those diesels are just generators.
ChuckKarma
Shit you're right. They should have fatass batteries, too.
kuriosly
Regenerative braking isn't that efficient though (not that it doesn't help)

Looks like they trained you well for your job.

I didn’t even catch the pun lol, I thought he was just being nice
cousteau
Wait wait, (1) are they like gigantic bike brake pads? (2) do they touch the wheel border, not the sides? Woah.
Samsungman
I understand what happened here, but F**K that title.
dreadfroggy
I believe in America, we call that "shelling".
Syphon02
I always heard it called 'flashing', though that may just be related to plastics doing this, not metals
Saro87
You are correct
PoppinLochNessHopster
Not slag/debris/bunch of horse shit?
HsuDoNihm
I... sure I'll call it that now. I used to call it "going to shit" but uh, I don't anymore.
Klingon00
Is that like galling? https://en.m.wikipedia.org/wiki/Galling
bigcuntry
Built up tread, shells are when the wheel itself chips. At least, that’s what freight car mechanics call it
dreadfroggy
Good point. I did not zoom in on the pictures. It is build up, not chipping/shelling.
guardian19d
Isn't that called a skid-flat or something?
jagl678
Built up thread
Saro87
Flat spots are caused when the wheel locks and slides on the rail.
Dorsk84
That's when the wheel stops and drags. This here is the brakes where just one enough to heat up and melt, but not stop the wheel.
ThelostWorldofAtlantis
Smell that coming from a half mile away.

Damn

Looks like we've got a whole bunch of railway people here! I'm doing my part!
Dorsk84
I know a few people who work at a railway in NH. Learned a little bit from them when we at their place hunting.
