Automatic control of crossing closure on characteristics of approaching train

The paper considers a method of controlling the crossing closure on characteristics of approaching train that will enable the crossing closure so that the train is guaranteed to have time to stop before the crossing in the case of the forced stop of road vehicles on it. In order to realize the method the authors have developed algorithms and structural scheme of the system that contains locomotive and stationary equipment, have formulated the requirements for the equipment of the existing locomotive microprocessor systems and complexes and have justified the choice of the locomotive equipment for realization of the proposed method and the system.
