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?

I get something in that ballpark, which suggests a few things are wrong. (1) the time window for deceleration is probably ~15 seconds (slams on brakes immediately, keeps on them) (2) an empty passenger train could be 1/10th as heavy as you suggest
