> Reversing the engine is accomplished (on DC units) by reversing the reverser lever and advancing the throttle to notch one.
With EMD units, all you have to do is throw the reverser (assuming the unit isn't isolated). One motor of a pair will regenerate and cause the other to rotate in the opposite direction. Subsequently opening the throttle will try to drive both motors in the opposite direction. And no, reversing the motors isn't a more effective brake than using brake shoes without the wheels sliding.
