Siemens Automates Paris’ Busiest Subway Line

France’s longest established metro system is now fully automatic, thanks to Siemens Infrastructure & Cities’ fully automatic Trainguard MT CBTC train control system.

Initial Situation

Métro Line 1 is Paris’ busiest subway line, and it was important to complete the automation project with minimal disruption to service. Transporting an average of 725,000 people per day, including numerous commuters heading to Paris’ business district La Défense and tourists wishing to visit Paris’ most well-known sights, the RATP decided it was necessary to increase train frequency, while improving efficiency.

Siemens’ thirty-year relationship with RATP and proven excellence in the field of CBTC migration projects led to Siemens being awarded the order to equip Paris with a driverless metro system by the Parisian transit authority RATP (Régie Autonome des Transports Parisiens) in November 2005.

The market situation calls for driverless operation for new subway lines, and an option that must be considered for existing lines. Siemens’ driverless solutions allow for environmentally-friendly operation and improved flexibility and frequency, and the goal was to improve passenger comfort on Paris’ busiest line.

Customer Challenges

Line 1 is the oldest and most heavily frequented line in Paris, in existence for over 110 years. The driverless system had to be implemented with as little disruption to service as possible, ensuring that commuters and tourists were still able to reach their destinations while the Trainguard system was being implemented.

Our Solution

Siemens’ Trainguard MT CBTC (Communications-Based Train Control) system ensures trains have an optimized headway, meaning that specific distances between trains are adhered to, while allowing flexibility – in case of trade fairs and sports events, trains can run more frequently, while the margin between trains remains safe.

Trackside and on-board equipment was also supplied to the RATP, along with telecommunication and radio systems.

Following the implementation of the system, trains on Line 1 can now run every 85 seconds – instead of the previous 105 seconds. The system also allows for full interoperability, and the automated trains can run alongside the manually-driven MP 89 CC trains without issue. Passenger safety was also a priority concern, and special doors ensure safety at all 25 stations.

The first driverless train was implemented in November 2011, and all 49 driverless trains have been in operation since 2013. Siemens’ Rail Automation Business Unit implemented the project with minimal disruption to service.
