That train will just keep coming. Once such a freight train is going you better get out of the way. The amount of kinetic energy that’s coming towards you is dwarfing compared to a measly tank.
A train of 8000 tons at a velocity of 30 km/h roughly has the kinetic energy of 66.39 kg TNT.
I don’t think your units make sense — kinetic energy has units of energy, but “kg TNT per second” is power (about 4MW). (I think just remove the “every second” and it’s correct?)
Edit: parent edited comment.
You’re right, but “every second” was meant more as a display of the energy in the train, like a large explosion “every second”. Is that very wrong?
It seems to be a lot, how does it compare to an artillery shell? The tank doesn’t look like it fared too badly.
Artillery shell with 1 kg of TNT has explosion energy of about 1 kg of TNT
