The fact that all wheels slip by the same amount shows that there is some pretty advanced motor control going on. Apparently, the whole traction system is designed to slip in exactly this way under high load and low friction.
In Germany it's called Superschlupf (super slip), which refers to a small amount of wheel slip providing slightly higher traction than no slip at all. Even more wheel slip (at 0:35) leads to less friction and more wear, so engineers try to avoid it. Some people call it Superschlumpf (super smurf), which is a pun.

Still the old 151 was better. A co-co with a massive weight. Co-co's are hardly made anymore and modern locomotives are way to light. Power is useless without weight.
Engineer's POV : In traction, low adhesion may cause a wheelset to accelerate more quickly than the train (wheel spin) to the point where it can damage the traction system or result in damage to the wheel and rail (rail burn). Wheel slipping occurs when tractive effort exceeds adhesive weight whereas sliding occurs when braking effort exceeds adhesive weight.. When Tractive effort is more than adhesive weight, difference in power accelerate the wheel which results into grinding action on the rail.
I'm just wondering why hadn't the conductor increase the rail adhesion by adding sand. Since both steel rails and wheels have less friction coefficient. Also, Bombardier Traxx 2 and Siemens EuroSprinter are lighter in weight but have more torque which results in relatively low tractive effort than say GE Evolution series (300 kN vs > 800 kN well this also has to do with axle arrangement configurations..). Even high adhesion locomotives in the US struggles when fully loaded so why not use sand when it is available? Maybe it ran out?
@@josephsmith8275 The heaviest trains require the highest friction and the heaviest locomotive.

Well mechanically at 0 rpm you are at 0 power.

Motor efficiency is some 98% at nominal power of 1.5 MW, what means armature losses of some 30 kW. These losses are roughly the same at the standstill, so entire loco dissipates in turn 120 kW + the mechanical power when it moves.

Looks like an AC traction motor locomotive. No brushes, and AC technology controls slipping more effectively than DC. Looks like a lot of wheel "creeping" going on. EMD units will spit out sand once excessive slipping is detected (past creep) ... but AC can control slipping so effectively that the operator at times may just patiently keep lower throttle until he/she pulls away. I did not realize that Europe had sanding restrictions but the comments make sense (avoid switches). Note: earlier EMD AC tech was based on Siemens AC tech and I wouldn't be surprised if this is in fact a Siemens loco in the video? Even ABB uses similar AC tech. I think the loco and the operator are doing their jobs and letting the technology do what's best for the conditions. I tend to not second guess operators. Thank you for the video at showing what a loco can do under slippery conditions. I always admire Euro railroad operations. Peace form USA ...
Easy, the driver forgot to enable the sander, it's not automatic application like on U.S. locomotives, in Europe's engine there's a Sand button which require manual press, sanding is REQUIRED in case of Wheel Slip and Wet conditions.
@@Jeremy974 Our brush class 60's in UK auto sand it can be isolated but auto sand isolate takes out most of wheel creep system and obviously EMD 66's are auto sand . I agree with you sand is needed with poor rail conditions ie wet rail
There is no technical reason why DC could not achieve just the same result. But the point why you won't see it with older DC motors is, to implement it you need fast response of the traction regulator and for that you need it to operate without much filtering towards the motor itself. And in order to do that efficiently, you need rather high PWM frequencies. But once you have the technology able to use these high PWM frequencies, that is the same technology needed to implement an DC to AC (variable frequency) inverter to feed way simpler, cheaper to make and maintain, more reliable, more efficient and more robust AC traction motors. So with all that present there it would be just silly to still keep using the DC traction motors...
Aha, so that's why. In Sweden there is no restriction or really any problem using sand, we just sand away. We also use a much more coarse-grained sand in our domestic locomotives Rc than the dust in the Traxx.
Of course sand is also used for traction in Germany and elsewhere in Europe, it's just prohibited to use sand on already slipping axles. So shut down the power, then start using sand. But in cases like this, on flat terrain, wasting sand isn't really necessary if you'll get to your desired speed anyway, even if it may take some time. You'll save it for steeper grades where you couldn't hold your speed or start moving without using sand.
Of course it will slip. With 2000 tons to pull, it has to struggle. Reduce the load and see how light it will travel. Over-weighted trains not only stresses the locomotive driving bogies but also the rail tracks. The excessive weight can buckle the tracks and press them hard into the ballast.
Over-weighted? 2000t are the average weight one loco is pulling. In germany, two locos of the year 1972 are pulling a 5000t Coal Train without problems.
Something is not right here! If the available slip-slide technology works, sanding would start right from the beginning when the slip-slide is detected, which normally takes under a second to start sanding.

Slipping of wheel from rail line is caused by less friction. This can be removed by broza powder to be splinter on the track just ahead of engine wheels. This can be sprayed on the rail track.

Will Railway authority used this type of sprinkling by a switch on the drivers seat instead of asking some of his staff to put stones on the rail track.
A co-co arrangement would have worked. That's the problem with electric locomotives, lack of weight results in lack of tractive effort. This same loco might have no issues notching up to about 80 miles with the same load in motion, but it struggles to start from rest.

They usually use only 2 wheel boogies today because 3 wheel boogies means more wear for the rails. If it's too heavy at a steep section a second loco for pushing (to reduce the force on the couplers) is the best option.
The number of axles is ultimately determined by the weight the rails can carry a 120 Lb rail can only carry around 30 to 40 lb so thats the maximum weight each axle can carry
Electric unit nor 'empty' train equate to nothing without more information. Did the empty train weight 500 tons or was it empty at 3000 tons. Were the brakes not kicked off yet? Was it on some incline as well and was it raining too? Apparently wheel slip was working. I have no idea why sand was not used nor if it is not allowed in some areas. The poster should include this information.
Having seen this video and the slippage of the wheels, it is no small task to get the train moving up to a decent speed. Considering the extremely small amount of wheel surface area touching the rail, it would seem that the solution might involve increasing this surface area during start-ups and likewise at final braking slowing down. Perhaps some kind of dual tractor belt on each truck on the locomotive between the foreword and rear wheels, which would be synced to wheel rpm could be used. This would be retractable, down from speed zero and raised at speed once the inertia of the train is in balance. Once retracted the tractor belt would be put in neutral.
There is already a solution, and has been used for quite a time: sand. Near the wheels, there is a small scope where the sand will dispense to increase friction. ua-cam.com/video/Cjw4Bzt1SOw/v-deo.html
Increasing contact area does not increase traction force. F = μN where μ is a coefficient of friction (dependent only on properties of materials in contact) and N is weight applied Contact area isn't even in the equation so it's irrelevant. To increase traction force you'd need to either increase coefficient of friction (use rubber tires or put sand on rails, which locomotives often do) or increase weight of the locomotive. But if you increase weight inertia also increases so it will not improve stopping time.
@@ExecutionSommaire That's why it is important to stick to the equations and actual physics of what's going on. Sometimes what's "obvious" from everyday experience can turn out to be false. This is a widespread fallacy that with more contact area you get more friction. μ actually doesn't increase with area.
Nozzles on both sides of the wheels serve to blast sand. The sand increases the friction force between the rail and the wheel, so the wheel does not slide. Why isn't the engineer spraying sand ?
@@Pferdesalami it maybe i didn't think about it, i just think if the driver are not use the sand, the train will hard to moving because the train wheels and the rails are use iron, if the weather are start rain, that will make the rails be wet and will make the train can't quicky stop or start go, so that i think the sand is very useful for train.
This train driver is just very badly trained. The brakes of his train are stil in action when he starts (and he forgets to turn off the red lights on the back side : it can be vers dangerous in some countries)... Private companies really badly train their drivers in Europe (I’m train driver in France and i’ve a lot of examples)
TRAXX series locomotives have enough power to pull themselves through their brakes, done it once myself too by accident... :S. And if there's one thing I learned it's to never like French drivers, they think they're the best in the world usually especially since in France they don't want any drivers from outside countries to drive in their countries :D

Det var ca 600 tonn bak loket
Du är ju Svensk, eller?;)

@@sally708 It was pulling about 600 tons.

I am not Einstein but i simpley think that if you throwdown some sand as it is used when it breaks, it would work the same. So release some sand.
Now that was one heavy empty railway car🕶
I cant see, sant applying by nozzel...!! To reduce slipping already given sant box assembly in locomotive...!!😊
Electric unit nor 'empty' train equate to nothing without more information. Did the empty train weight 500 tons or was it empty at 3000 tons. Were the brakes not kicked off yet? Was it on some incline as well and was it raining too? Apparently wheel slip was working. I have no idea why sand was not used nor if it is not allowed in some areas. The poster should include this information.
Ma friend check this video ua-cam.com/video/7n4GmvCsAJ0/v-deo.html its the same loco and youl see the problem why it sliping :)

I suppose everyone getting out and giving it a good push wouldn't help...
Getting out of what? Looks like it is a goods transport.
Woah...
Can I use this video in my train compilation video credit to you in video will be given
Same comment, Mr Tiger needs some sand on those rails.
You are not allowed to use sand near/in a rail switch in Norway, unless it is an emergency stop.
I like how someone has scrawled 'Tiger' in the dirt on the orange part. xD
Having seen this video and the slippage of the wheels, it is no small task to get the train moving up to a decent speed. Considering the extremely small amount of wheel surface area touching the rail, it would seem that the solution might involve increasing this surface area during start-ups and likewise at final braking slowing down. Perhaps some kind of dual tractor belt on each truck on the locomotive between the foreword and rear wheels, which would be synced to wheel rpm could be used. This would be retractable, down from speed zero and raised at speed once the inertia of the train is in balance. Once retracted the tractor belt would be put in neutral.
There is already a solution, and has been used for quite a time: sand. Near the wheels, there is a small scope where the sand will dispense to increase friction. ua-cam.com/video/Cjw4Bzt1SOw/v-deo.html
Increasing contact area does not increase traction force.
F = μN where μ is a coefficient of friction (dependent only on properties of materials in contact) and N is weight applied
Contact area isn't even in the equation so it's irrelevant.
To increase traction force you'd need to either increase coefficient of friction (use rubber tires or put sand on rails, which locomotives often do) or increase weight of the locomotive. But if you increase weight inertia also increases so it will not improve stopping time.
Perhaps a hydraulic arm that wraps around the flange and pull to increase the normal force on the wheels
@@РоманПлетнев-г3э The effect of the contact area is hidden into μ. It's obvious by everyday experience that large surfaces provide more friction...
@@ExecutionSommaire That's why it is important to stick to the equations and actual physics of what's going on. Sometimes what's "obvious" from everyday experience can turn out to be false. This is a widespread fallacy that with more contact area you get more friction.
μ actually doesn't increase with area.
This is how trains do burnout 🤣🤣
No sand???
maybe only available on opposite side
PrimZ666 What is sand?i remember i watch it in tsw
sand is used for adding more additional friction , so there is no steel wheels againts steel track,
PrimZ666 oh thank you! Finally i know about sand :)
u should find a video explanation about it for better understanding :)
Nozzles on both sides of the wheels serve to blast sand. The sand increases the friction force between the rail and the wheel, so the wheel does not slide. Why isn't the engineer spraying sand ?

Finally, a live video of me attempting to paying off my student loans
I think the train is screaming like crazy 😧😏
I assume that polished surface is for braking like a disc brake, I've never seen that before?
Yep, its a disk brake ;)

So why was the sanding equipment not functioning???? It’s right there….🤔
if i'm train driver, i will use sand to help my train moving.
but it damages the rails
@@Pferdesalami it maybe i didn't think about it, i just think if the driver are not use the sand, the train will hard to moving because the train wheels and the rails are use iron, if the weather are start rain, that will make the rails be wet and will make the train can't quicky stop or start go, so that i think the sand is very useful for train.

Traction motors are tooo powerful
This train driver is just very badly trained. The brakes of his train are stil in action when he starts (and he forgets to turn off the red lights on the back side : it can be vers dangerous in some countries)... Private companies really badly train their drivers in Europe (I’m train driver in France and i’ve a lot of examples)
Ben Nissa but...how can he continue with brakes on??? He should check it if the train is slow while starting to move....
You’re not a train driver stop lying and with the huge convoy with brakes applied he wouldn’t have moved a bit...
TRAXX series locomotives have enough power to pull themselves through their brakes, done it once myself too by accident... :S.
And if there's one thing I learned it's to never like French drivers, they think they're the best in the world usually especially since in France they
don't want any drivers from outside countries to drive in their countries :D
Ha ha do you think the Traxx has enough power to pull 600 tonn with the brakes on........funny guy.
@@Xenoniuss_
They say the foreign drivers don't know French
he forgot to active traction control system
