It boggles my mind how much a freight train can tow. I feel like something should break before that much power can be generated. How does it work? What’s the engineering feat that enabled this? Can you put it into perspective? I mean it’s obvious just by looking at it, but what does it compare to? Thanks!

In short, freight trains use electric motors to turn their wheels. I’m not sure the exact physics behind it but electric motors produce WAY more torque than gas or diesel motors.
That’s why teslas have more towing capacity than some trucks. It has to do with the fact that a magnet and electric current are turning the motor, not a chemical explosion “pushing” against the force of the train.
Freight trains use a diesel engine to generate electricity, then transfer that electricity into an electric motor that turns the wheels.
