Propulsion was furnished by a bipropellant (monomethylhydrazine and nitrogen tetroxide) liquid-fueled rocket engine which could be gimballed up to 9 degrees.
The high voltage propulsion control was replaced with a safer low voltage propulsion control, which utilized battery voltage (32 volts) to control the train's motors.
The term electric vehicle refers to any vehicle that uses electric motors for propulsion, while electric car generally refers to highway-capable automobiles powered by electricity.
