Regenerative vehicles are working even on less busy lines. On such lines, when the train density is so low that regeneration is liable to be ineffective and, notably where the gradient section is long, the brake performance will be poor and the brake shoe will be heavily abraded. Therefore the resistor is mounted on the vehicles and the regenerated energy fails to be fully consumed, the residue is consumed at the resister. It is desirable not to mount the resistor on the vehicle and avoid an increased vehicle weight. Then, to mount or not should be decided with clever judgment.<br>Therefore, we studied the effective coefficient of regenerative energy which provides the criteria for judgment. We looked for an estimation formula of effective coefficient of regenerative energy, and showed that changing the number of trains, the coefficient will not change so much. We proposed a technique of estimating manually and by a simple program based on that formula and confirmed that the calculation can be precise enough to be practically employed.
