Ile-de-France Tramway Line 9 (T9) is part of a series of tram lines that constitute the Ile-de-France tramway network in France. It connects the Porte de Choisy Paris Metro station to the centre of Orly.

With 3.5 million passengers served by around 5,600 trains a day, the railway network in Ile-de-France is the world’s second-busiest rail network after Tokyo, Japan. It is also among the densest rail networks in Europe. Opened in April 2021, Tramway line 9 will meet the transport and mobility needs of residents in the Ile-de-France region.

Ile-de-France Tramway Line 9 details

The T9 tramway links different modes of transportation in the Ile-de-France metropolitan network.

It will enhance the region’s transportation options by offering connections to the existing transit network lines C and D of the RER suburban train, line 7 of the Porte de Choisy metro and the Trans-Val-de-Marne bus route and upcoming projects such as Grand Paris Express rapid transit lines and T Zen 5 bus line.

It replaces the 183-bus line, one of the busiest bus lines in the area, and provides a rapid and more reliable service to the Val-de-Marne department.

The Green Track track-laying technique used for the project ensures efficient water management and reduced maintenance costs.

Route of Ile-de-France tram line 9

Tram line 9 reduces the travel time between Porte de Choisy metro station in Paris and the heart of Orly from 60 minutes to 30 minutes. It offers connections with the metro, Val-de-Marne bus routes, RER and tram.

The 10km-long tram line features 19 stations located 550m away from each other, serving the towns of Ivry-sur-Seine, Vitry-Sur-Seine, Thiais, Choisy-le-Roi, Orly-Ville and the 13th arrondissement of Paris. The six towns will be served throughout the week, with a five-minute frequency during peak time.

The new tram line is projected to carry up to 80,000 passengers a day.

Rolling stock

Alstom’s Citadis X05 trams, known as ‘lumière’, started commercial operation on tram line 9 in April 2021.

The 45m-long Lumière tram has the capacity to carry up to 314 passengers. The entire cost of rolling stock is financed by Île-de-France Mobilités, the public transport authority of the Paris Île-de-France region.

The vehicle features eight double doors on each side and wider gangways, which help to enhance passenger flow and increase the passenger exchange rate by 20%.

A light signature that is a striking feature throughout the tram set offers improved views of doors opening and closing. The light scheme includes a red line of light at the time of door closing, a green line to indicate door opening and a white line when the tram is in motion. Interior features include 100% LED lighting, 45% glass surfaces, eight extra-wide multimedia displays to enable the visual display of maps, USB sockets and bench seating.

The improved design offers greater comfort and an improved passenger experience. Reduced energy consumption of lumière from its traction and auxiliaries, including efficient LED lighting and air conditioning, makes the tramway an energy-efficient service.

Contractors and key players involved

Île-de-France Mobilités ordered 22 Citadis X05 trams from Alstom in November 2016. The trams were delivered between November 2019 and December 2020. The lumière tram was designed by a partnership of Alstom’s Design & Styling teams and design agency Saguez & Partners and built at Alstom’s La Rochelle site in France.

Colas Rail was awarded a contract to construct the rail track and install the surfacing. The contract for the launch and operation of the tram 9 line was awarded to Keolis in July 2019.
