FIELD: railway transport. SUBSTANCE: trucks running ahead of locomotive are used at emergency stopping of train. Trucks are connected with locomotive by steel cable. Front truck is set into operation by electric motor installed on truck and supplied by generator along this cable. Generator is driven by locomotive wheels. Truck tends to run at greater speed than locomotive providing constant tension of cable. Inertia current breaker is mounted on this truck. Lock for fixing the truck in middle of cable is installed on second truck. If track is damaged or front truck collides with an obstacle, inertia current breaker operates which leads to emergency braking of train through automatic system. EFFECT: reduced number of equipment required, simplified servicing, low cost. 5 dwg
