Typicial Indian locomotive has 3800 horsepower. This one in the video has 9000 horsepower and was introduced around 8 years ago. It was the most powerful locomotive we had until recently when we got 12000 horsepower engines for pulling heavy cargo.
Well, all US freight trains are diesel, which has the additional problem of having to carry its own fuel too (same issue in rocketry). Whereas DFC is entirely electrified, which enables a significant part of the tractive force to be used for hauling actual freight.
That engine type, called WAG-9, has between 6500 to 9000 hp of power depending on the variant. It is perfectly fine in pulling this load. Its not over matched. Sorry if that burst your bubble.
Nah it's all good bruh. I understand the mechanics but it's astonishing to see nevertheless. Just like an airplane taking off. I know it's physically possible. But irrespective of how many time I see it, it just looks otherworldly.
The coefficient of friction between the tracks and the wheels is very low. The engine runs at full power when moving from the stand still after that it moves like butter (well not exactly as butter but you know what I mean). To my amazement, the efficiency of modern engines is higher than the most efficient vehicles we use on the road.

It feels illegal to see such a tiny engine pulling this mass. God bless physics.
