The T13 light metro line opens in Paris

A tram-train line connects the western suburbs.

The PARIS tramway line T13 entered service on July 6, linking Saint-Cyr to Saint-Germain-en-Laye in the western suburbs and serving 12 stations, including 7 new ones.

The new route extends over 18.8 km from Saint-Cyr, also served by RER and SNCF line C suburban services, to Saint-Germain-en-Laye where the exchange is provided with the line A of the RER by means of a new 190m passage equipped with conveyor belts.

The project involved the construction of a new station in Saint-Cyr and a new 750V dc electrified alignment between Lisière Pereire and Saint-Germain-en-Laye with two new stations.

The remaining 15.5 km is a section of the Big Beltthe great belt around Paris, which was fitted out by SNCF Réseau for the operation of the tram-train with 25kV ac electrification.

Five existing stations on the railway line have been refurbished, with platform lengths reduced to 42m to match tram-train vehicles and a reduced height of 320mm to allow level boarding. Accessibility has been improved by replacing footbridges with level crossings for pedestrians.

End-to-end journey time on the T13 is 30 min, with services operating seven days a week from 06:00 to 00:00. Peak frequency is every 10 minutes, with service every 20 minutes at other times.

The new line is expected to carry 21,000 passengers per day, offering an environmentally friendly and accessible alternative to the private car.

The T13 is operated with a fleet of 11 Alstom Dualis VLRs, ordered by the regional transport authority Ile-de-France Mobilité at a cost of €68.8 million. Each LRV can accommodate 250 passengers, with 90 seats, and is equipped with 10 screens displaying real-time passenger information and 36 USB ports.

The fleet is maintained in a new depot of 6500m2 at Versailles-Matelots, built by SNCF Voyageurs, equipped with a 120 m workshop building housing a wheel lathe. The T13 control center is also located here.

The new line is operated by Transkeo T13, a joint venture between Keolis (51%) and SNCF (49%). 45 drivers are trained to operate on the French national rail network.

The T13 infrastructure works cost a total of €306.7 million, financed by the French State (17%), the Ile-de-France region (53%) and the Yvelines department served by the new route.
