Dude’s a lineman. I don’t think I’d have either the quick thinking or courage to do what he did. You can see him hesitate for a second before committing. He apparently donated most of the reward he got to the kid for his education.

Damn. That’s a lot of momentum to arrest even for a 2 second window.

And the loco pilot applied emergency brakes giving an additional 2 seconds. twitter.com/rajtoday/statu

Rough calculation for fun. Normal speed 100-105 km/h but slamming the emergency brakes brought it down to 85. Train weighs I’d guess 10,000 tons? If it shed that energy over 5 seconds, I calculate a brake power output of like 213 MW. Did I do that right?

Less rough calculation. A typical Indian passenger train weighs in at around 1300 tons, so that’s a factor of 10 less, so we’re talking 20 MW brake power. If it was 10 seconds instead of 5, brings it down to 10 MW. Still a lot, but not outrageous.

Man, I had to double check this. I realize hummers are likely set up for torque but they’ve got factory V6s cranking out more than 300hp these days. EV may be there future, but at least ICE tech is still advancing

Is that tech advancing? Raw ICE power has never been hard if you had the volume to work with, so it has to be weight or compactness I guess. Can you now pump 300hp out of a smaller, lighter engine block?

In this example it’s with even fewer cylinders (reducing displacement). The major criticism of US OEM in days of yore was exactly as you described, laziness with displacement (1hp/cu in) while EU mfrs managed increased power with lower displacement.

Some material engineering certainly (though the transition from Fe to Al blocks has been taking place for some time), lighter components to reduce losses would certainly help We’re also cramming more tech than ever into cars. Helpful Nissan explainer👇
