This is a study on the two methods for enhancing the receptivity of a transit system third rail power supply when trains employing propulsion equipment capable of returning power to the third rail are used. All available braking energy of such cars is intended to be returned to the third rail. During periods of heavy traffic, accelerating trains will generally be present to absorb the power made available by braking trains. However, during periods of light traffic, accelerating trains are not likely to be available on the line and other means must be provided to absorb the braking energy. The two methods for providing such a sink are: (1) Addition of resistor banks on the wayside equipped with notching control to match resistance values and line requirements. The excess braking energy will be dissipated as heat. (2) Addition of DC motor driven flywheel sets on the wayside to absorb the excess braking energy. The excess braking energy will be conserved.
