We are investing to upgrade and maintain our ventilation equipment and electrical installations.

  • A breath of fresh air for the network
    “We are running more and more metro and RER trains to ensure the mobility of an ever-increasing number of passengers. This results in a significant temperature rise underground.”
  • Providing the energy for your transport
    “With 2,000 km of cables distributed under 500 km of roadway, our own high-voltage network provides 75% of the electrical power needed to operate lines, stations and premises on the metro, RER and tram network.”
