Putting into service the system for parallel-substation interlocking for line 6 of the Madrid Metro (March 2007)

In record time, CEFISA has carried out the engineering development, manufacture of equipment, installation, testing and put into service the system for parallel-substation interlocking for line 6 of the Madrid Metro. The system allows connection in parallel of the substations which reduces voltage drops, improves power efficiency, and increases both: the reliability of the system and the provided power to the trains. The system allows the Madrid Metro to handle an increased number of passengers and also improves the quality of the service provided.
