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.

More: 10MW for 10s is about 28 kWh. At the average Indian price of 7c/kWh it cost about $1.96 to save the kid (since the train would have had to use electricity to accelerate back up). They lineman got a Rs. 50,000 bravery reward (about $666). Total cost, ~$668
