“We are proud to have partnered with RATP and Île-de-France
Mobilités to complete this landmark
project that provides Line 4 with the highest grade of
signaling technology and automation services,” said Michael Peter, CEO of
Siemens Mobility. “Paris has one of the busiest metro systems in the world. Our
state-of-the-art CBTC signaling at GoA 4 allows trains to operate driverless
and be automatically controlled and supervised without any onboard
intervention. 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.”
For this project, Siemens
Mobility equipped the tracks, the technical premises and the 52 automatic
shuttles that will run on Line 4 with its digitalized systems and CBTC
signaling. Siemens Mobility also supplied the equipment and software for the Operation
Central Command (OCC), which manages the signaling system and the traction
power supply, as well as interfacing with the on-board and trackside systems.
Siemens Mobility’s digitalized
CBTC signaling will
allow RATP to safely increase capacity and accommodate more passengers on the
system. The ability to continuously receive updates on system status will also improve
operational efficiency, resulting in fewer delays and more up-to-date travel
information. Additionally, the automated system will reduce traction energy
consumption by up to 15%.
Line 4 is the second busiest
metro line in Paris. It carries 700,000 passengers per day, through 29 stations
that are spread over 14 km. The busy line, and the need to minimize the disruption
of passenger service, was one of the many challenges brought on by this project.
The automation of Line 4 needed to incorporate the work being done to extend
the line to its new southern terminal Bagneux-Lucie Aubrac, while also needing
to successfully interface with three different types of rolling stock (MP89,
MP05 and MP14). All features were successfully carried out despite the
challenges brought on by the pandemic.
