FIELD: transport engineering. SUBSTANCE: invention relates to devices for automatic control of running speed of hauling rolling stock. Proposed device has actuator acting onto locomotive which is connected by its input to speed governor first input of which is connected with output of comparator. One of inputs of comparator is coupled with speed sensor. Device is provided with intensity setter. First output of intensity setter is connected to second input of speed governor. Second output is connected to other input of comparator. Inputs of intensity setter are connected to speed sensor, setter and acceleration setter and through preset acceleration changing unit, to master controller handle and to speed governor. EFFECT: improved speed control. 4 dwg
