The overall objective of the project is to improve safety and security on the railway. The project contributes to this objective by: • safe movement of persons and goods; • reducing the costs of failures (short circuit, circuit break, variations in power voltages, influences of some sources of disturbances, etc.); • the most unfavourable situations should have the effect of blocking the switches in the position in which they are located, passing the signals to the stop if they were previously on the loose and signaling the disturbance; • increase the efficiency of the operation and maintenance of the Romanian railway network.
