Locomotives use a throttle lever to control power. It ranges from idle to "8th notch" with 8th notch being wide open. Normally a locomotive on its own, or when coupled to one other locomotive/empty freight cars, will start from a dead stop in 1st notch. As speed increases you begin notching up the throttle.

Really, the engine is there just to turn the alternator to power the traction motors. In 8th notch it puts out about 2,400 amps and 1,200 volts.
