These facades incorporate real-time information screens, displaying the waiting times for the next two trains as well as traffic-related messages to passengers. This allowed the installation of more than five kilometres of platform doors on the 29 stations of the extended line to guarantee enhanced safety. In order to accommodate the automatic rolling stock, the platforms were raised and reinforced while maintaining traffic. The proper functioning of the train driving, command and control system were tested during off-peak hours, in full automatic mode, but with an RATP supervisor present. “This truly modern system increases the reliability and availability of service, which will deliver an enhanced passenger experience for the 700k daily riders of Line 4”, said Michael Peters, CEO of Siemens Mobility.įrom mid-June 2022, tests of the functionalities began without passengers. Line 4 will operate three generations of automatic rolling stock (MP89 and MP05 automatic driving from line 14 as well as the new MP14, developed by Alstom). The OCC manages the signaling system and the traction power supply, as well as interfacing with the on-board and trackside systems. Siemens Mobility also supplied the equipment and software for the Operation Central Command (OCC) which was finished in partnership with the Atos – Colas Rail consortium in 2020. Siemens Mobility equipped the tracks, the technical premises and the 52 automatic shuttles that will run on Line 4 with its digitalised systems and CBTC signaling. Working towards automation since 2016Įxtensive work has been carried out since 2016, without any major interruption to traffic, according to RATP. The cost of its automation represents an investment of around 470 million euros, financed fully by the transport authority. The automation was requested by transport authority Île-de-France Mobilités, with the goal of complete automation of line 4 by the end of 2023. Also, the traction energy consumption should be reduced by up to 15 percent once fully automated. Other advantages include real-time adaptation of the service, increased safety and regularity, and more staff on the ground at the service of passengers, says operator RATP. With this, the transport capacity can be increased. The automation makes it possible that the intervals between the metro trains are reduced from 105 to 85 seconds. Operated by RATP, the line is the second busiest metro line of the Paris region. When it is fully automated in 2023, 52 automatic shuttles will run on the line. ![]()
