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.

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.

Just noticed the time stamp on the video. The train rounds the curve 2 seconds after the kid falls, then it’s 10 seconds to the pass. 3:54 - 3:56 - 4:06

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

Anxiety on the Engine: Alert loco pilot VK Jangid, who witnessed the Vangani episode from his driving cab as his train sped towards them, applied emergency brakes bringing down the speed, which gave Mayur Shelke a two-second margin to save the kid & himself. Details:
