Régie autonome des transports Parisiens (RATP) ordered from Stadler 12 service and maintenance locomotives powered by battery. The customised locomotives will complement the existing generation of vehicles from 2027.
This is the first order that Stadler has received from RATP and includes an option for 2 additional vehicles.
The new locomotives are part of an RATP project aimed at making the maintenance of the metro infrastructure more streamlined and more efficient. The four-axle locomotives are 15 metres long, equipped with fully automatic couplings and capable of double traction. They run on the standard gauge and are designed to accommodate the tight curves that characterise Paris network. These locomotives can be used on all 14 lines of the Paris Metro including the routes which trains with conventional steel wheels run and on those used by vehicles with rubber tyres (Pneu-Metro).
The RATP locomotives haul heavy work trains to construction sites on the metro’s rail network. They are authorised to operate in parallel with normal metro services, as well as on the routes operated without drivers. They pull around 120 tonnes in single traction and around 240 tonnes in double traction.
The new locomotives are flexible in use, low-maintenance and environmentally friendly. Their high level of redundancy means that they are both very safe and very reliable. This is especially important for operation in tunnels parallel to metro traffic and on construction sites. In battery-electric drive, energy is transmitted to the vehicles via the pantograph or by using on-board traction batteries. In normal operation, the conductor rail supplies the electrical energy of 750 V. On construction sites, where the conductor rail is switched off, the locomotives are powered by traction batteries. These are then recharged through the conductor rail.
The service and maintenance locomotives will be used by RATP to carry out service, maintenance and repair work on the infrastructure of the Paris metro network, which is approximately 245 km long.
