Wheel slipping and sanding with very heavy train.

- Moving heavy train uphill from standstill sometimes leads to adhesion loss. Sand can be sprayed under the wheels to restore and maintain traction.

This is my life.....ignoring my problems and watching train videos for the entire day......
It's better than mindlessly watching reality shows
hahahaha
Interesting , I’m not sure why but i always thought they would use way more Sand for this instead of what appears to be a very Precise minimum amount meticulously placesd ? obviously it’s a very wellEngineered Process (Pun Intended )
Tc train can you make a new pantograph video please
that would be cool
but i wonder if he can legally do that and i think its dangerous to mount a camera
best i don't
Amazing footage..
what kind of brakes were used? the breaking pads were not applied, at least on the locomotive..
These were not brakes this was sanding done when the wheel slips its releases small particles of sand which stops wheel from slipping and provides grip and also its limited!!!
Dynamic braking maybe.
Normally they don't use the locomotive's brake on longer trains to spare it, because it costs more to replace. On a train with 20 cars, it has little effect on overall braking performance. For example on a Hungarian Class 431, there is a foot switch, which when pressed keeps the locomotive's brakes released, despite the fact that you're using the train brake. As soon as you let your foot off the switch, the locomotive's brakes get engaged too.
@@Alexander470815 yes, maybe. This electric locomotive (68E) have regulated rectifier for smooth two-step rheostatic brake.
Outch it hurts, and I have question. It is a relative old locomotive and I'm wondering, why it doesn't have Anti-Wheel Slip Brake-Function. Which applies for a 1-2 second the direct brake to around 1-2 bar to stabilize the wheel and then you can add sand. Because, if you directly add sand into the wheel slip like this and your locomotive gains instantly traction, it puts a lot of stress onto the couplings, and cause to break it. Possible, way.. would be to add a bit direct brake by the driver itself.. just not for too long or the thermic stress on the wheels will be too much.
I don't have enough hands and fingers for all these things at once. There is no such automatic function in this locomotive and manually operated direct brake reacts much slower than sander. We often use the brake in slippery conditions to clean and dry the wheels. The original automatic anti-slip function, which is no longer existent, also applies sand. It is not so stressful if the slipping is suppressed in the very beginning.
There is no anti-axle blocking mechanism. This locomotive has only protection against prolonged slip, that trips the main 25kV contactor. Second generation locomotives from Škoda, 69E, 71E, 99E are equipped with fully automatic slip elimination, that can adaptively limits power deliveded to traction motors via SCR pulse drives. Those were state of the art machines at its time.
We don't have any protection, tripping the 25 kV switch. It can be sometimes tripped by the overcurrent protection of the non slipping motor from the pair due to rising the voltage when the current of the slipping motor decreases. This is actually what happens at 0:27.
@@TC-Rail Dunno, I drive myself relative old locomotives like the Br 110 built around 60s. My arms are somehow enough, although I don't know exactly the cab layout of this beauty. The Stabilizng System, I was talking to, is only automatic in our Br 111 and Br 151. It is called, "Schleuderschutz Bremse" in German. I had once the unlucky moment, where a magnet valve didn't work anymore for the stabilizing brake and had to manually use the direct brake to save sand.
Although, you're already in rather better position with the iron block brakes, because the rough surface of the wheels help in this case. Tbh, can sadly not judge much about the situation without my body o' meter, how it feels.
@@TC-Rail Yes, i meant that - the "slip" relay, that trips on voltage difference between motors in one group.
Great movie! Cheers, Fabrizio
Nobody steals your camera ? And do you get back the camera?
I love this videos
Very nice - thank you
Is it Czech lokomotive 121 or 122 or 123 or 130 or 131
Škoda 68E2 - BDŽ/TBD 44.
Jak by se tam asi taková uhelka a hrbatice vůbec dostala ? :D
Neni to uhelka jako 122 nebo 130. lokomotivy typu 68E byli vyrobeny pro univerzální službu BDŽ v 149 kusů. Soukromnik TBD-TP koupil nekolik z těch a po generalní opravu v ČZ-Loko je použiva na své uhelné vlaky.
Great video. ☺
Super video !! Very different
Trine kay wheel sleep hoty hay to balu ratey sulpay hotey hay
Osm capture
Really interesting video
excellent
Nice , it is a Sulzer locomotive ???
No, i guess. It is a Skoda😀
@@viktormkdrailfan simply clever
Guessing from the roaring fan, i think it is 68E too
😎
The wheel is really big as watching on a 65inch tv
Interesting
I want full view of this engine plzzz
Това Шкода ли е
Wheels move even faster when they r dragged
what loco?
