Other electronics introduced during the rebuilding give constant horsepower excitation control, and motor temperature control to allow maximum tractive effort to be maintained down to the point where the motor is in danger of overheating.

• 在改造过程中使用的另一些电子技术是恒定马力激发控制，以及发动机温度控制，以使在发动机过热温度以下保持最大的牵引力。
