Each TGV seats 500-700 people, about 100 to 500 times better than you RR average model 3. And goes a lot faster. I'd be curious to know the M3's mileage above 3

I thought regenerative braking was a strong point of trains? The motor is probably of comparable efficiency, I expect power electronics to be worse, indeed.
- londons_explore 4y agoThe train is capable of regen braking... But frequently the infrastructure is not. A train braking can be many megawatts of power, something that can't be dumped on the electricity grid of a small town without a bit of planning in advance. So, where capacity to dump the power can't be certain, regen braking isn't done, or is at least limited.
- Chilko 4y agoThis sounds like a great application for supercapacitors. Regen charge the caps when braking to enter a station, and use that energy to accelerate back out of the station
- Schroedingersat 4y agoA 400t train at 300km/h is a gigajoule or two. That's a decent chunk of the weight of the train in capacitors.
