Because you have to get the train moving. It's not practical to slip a
clutch to get a million tons of train moving.
When motors and generators get to this size they are typically in the high
90s for efficiency. The total efficiency (generator to motor) is probably
at or above 90%.

Life is hard. But it's harder if you don't know how the world works!
