All the power that goes into the trains ends up as heat outside of them. With the constant braking/accelerating, that's a lotta power. Just the axle motors pull 200-400 KW per car, or at least 2 million watts per train, and that figure is at only 300hp per car.If the braking energy were put back into the power system instead of being dumped as heat, the stations & tunnels would be a lot less miserable. |
