Abstract
Abstract In an electric rolling stock which tracts non-powered cars in which the number and the weight of freight cars and passenger cars vary by a large margin, setting forward of notches in the case of powering operation was very difficult and has been left to the ability of the operator. An automatic acceleration control portion (13, 3, 5a - 5n) provided with a speed-tractive force pattern (Fig. 3(a), (b)) with the weight of freight cars and passenger cars as the parameter and a conventional manual acceleration portion (4a - 4n) are provided, and in case of manual acceleration, notches are set forward after throwing the automatic-manual changeover switch (6) onto the manual side, and in case of automatic acceleration, acceleration is performed only by selection of above said parameter and powering instruction by the operator. With this, complicated powering operation becomes simple, and changeover is made simply when manual operation is required.
