TRAIN RESISTANCE, POWER AND ENERGY REQUIREMENT OF M-U CARS

Equations to be used in determination of multiple-unit train resistance, power and energy requirement are developed. Curves are presented for air resistance in tunnels. For open air the effect of wind speed and direction is also analyzed. Methods are presented for energy requirement optimization. Considerable energy savings can be realized by using these methods as guide lines for operational criteria. This study extends the work of W.J. Davis, Jr., for all kinds of M-U cars. The Davis equations were prepared and still are successfully used for conventional rapid transit train speeds and shapes, but not for high speeds and streamlining.
