France: Alstom’s New-Generation Citadis Tram Launches on Line T1
Alstom has officially launched its new-generation Citadis tram, known as TW20, into passenger service on Line T1 of the Île-de-France Mobilités network.
Alstom has officially launched its new-generation Citadis tram, known as TW20, into passenger service on Line T1 of the Île-de-France Mobilités network.
This modern tram replaces the region’s oldest trams, some of which have been in operation since 1992. It offers improved capacity, accessibility, and environmental performance.
The TW20 fleet will gradually come into service along the T1 line, connecting Asnières-sur-Seine and Noisy-le-Sec station. The vehicles are operated by RATP with full funding from Île-de-France Mobilités.
“The entry into service of the TW20 on the T1 line represents a major step forward for mobility in the Île-de-France region. This resolutely modern, state-of-the-art tram will transform travel conditions for thousands of Parisians who use it daily. This achievement testifies to the commitment of Alstom’s teams, who continue to innovate to meet the needs of passengers while contributing to a more sustainable mobility.”
The new Citadis trams are 33 metres long, 2.40 metres wide, and accommodate up to 200 passengers—15% more capacity than the previous rolling stock.
They each feature six wide double doors on each side, including at the ends, to ease boarding and alighting. Meanwhile, a pivoting bogie under the driver’s cab minimises the gap between doors and platforms, improving accessibility for passengers with reduced mobility.
The TW20 also offers several features to enhance the passenger experience:
- Air conditioning for climate comfort
- Dynamic passenger information delivered through 20 screens, complemented by audio and lighting systems
- USB charging stations (32 sockets) for passenger convenience
- A video protection system to ensure onboard safety
What’s more, the trams are equipped with advanced technologies to simplify maintenance and improve reliability, including real-time diagnostics via sensors, a streamlined set of spare part references, and enhanced accessibility of components. These features ensure optimum availability and reduce downtime.
In addition, the new trams are designed to reduce energy consumption by at least 30%, thanks to a more efficient traction system and optimised climate control. They also feature 100% LED lighting and are 95% recyclable (with 99% recoverability).
The vehicles have been made in France, with eight of Alstom’s sixteen sites in France contributing to their design and manufacture.
