Siemens to Provide CBTC System for Line 14 of the Grand Paris Express

RATP (Régie autonome des transports parisiens), the operator of the Paris metro in France, has placed an order with Siemens for the CBTC system (Communications-Based Train Control system) of line 14.

This line is the backbone of the Grand Paris Express, the planned new fully automated transit network for the French capital. It is the largest transport project in Europe and will support the development of the Greater Paris into a sustainable metropolitan area. The contract comprises the Grade of Automation 4 (GoA4) Trainguard MT CBTC and an option for maintenance services over the system’s lifetime.

Grand Paris Express Line 14

Thanks to its proven technology, Siemens is ensuring guaranteed availability, maximum throughput and enhanced passenger experience. The system is expected to go into operation in 2024. By then, the capacity of line 14 will benefit 40,000 passengers per hour and per direction, up from 30,000 today, making it the most frequented line of the Paris metro. It will allow passengers to travel directly between the Orly airport and the Paris city center and will serve the north of Paris through to the Saint-Denis Pleyel station.

The extended line 14 route will be 28 kilometers long with 21 stations. The work comprises replacing the existing CBTC system with a new one on the existing line sections and the existing 35 trains on-board. Furthermore, Siemens will install the CBTC system on the line extensions and on the whole fleet, which will increase to 72 trains in 2024. The contract also includes an operations control center and the implementation of a shared backup operations control center, with a training resource for the operators.

Michael Peter, CEO of Siemens Mobility Division, said:

“RATP’s continued trust in our CBTC solution demonstrates their commitment to meet the demands of Paris’ and the Ile-de-France region’s constant urban expansion through infrastructure refurbishments and extensions, helping retain the region’s development in a sustainable way. It also ensures continued optimal operational performances, with an eight-car train every 85 seconds. With this new contract, Siemens will extend the backbone of the Grand Paris Express, enabling RATP to provide easier and more efficient connections for passengers more safely and comfortably”
