ENERGY EFFICIENT RAIL TRANSIT OPERATION

The paper investigates the energy consumption characteristics of modern rail rapid transit. The paper shows the variation in energy consumption caused by different operating policies and design characteristics of the rail transit mode, and points out the energy economies of improved design and operation. Five variables are analyzed using a rail transit performance computer model that simulates the performance of a rail transit train whose operating characteristics are specified by the program user. The simulated train runs over a track segment established by the user and a performance log of train speed and acceleration along the track segment plus the rate of energy consumption and cumulative energy used are output by the train performance program. The analysis indicates that of the variables studied, the most promising ways of reducing rail transit energy consumption are to include a coasting phase with reduced maximum speeds in the trains' performance cycle and to adjust the track vertical profile. /Author/
