Abstract
A backup power system for a railroad power unit includes an emergency backup generator that enables continuous operation of both traction motors and accessories on the power unit when a main generator and/or an accessory power unit (APU) become inoperable. The backup generator can provide power to accessories on the railcar when the APU becomes inoperable and when power provided by the APU is diverted to the traction motors due to the main generator becoming inoperable.
