Brest Expands Network With Second Tram And BRT

BREST, FRANCE – In February, the Bibus public transport network in Brest, Brittany, expanded with the inauguration of Tram Line B and Bus Rapid Transit (BRT) Line D. The project, awarded in 2021 and coordinated by Brest métropole aménagement (BMa), adds approximately 10 kilometers of new public transport lines and 12 kilometers of associated bike lanes. The new services are designed to improve mobility for the metropolitan area’s 215,000 residents.

What Is the Full Scope of This Project?

The “My network is expanding” project delivers two major public transport routes and significant urban redevelopment. The new Tram Line B connects the central SNCF train station to the Cavale Blanche University Hospital, while the electric BRT Line D links the station to the Lambézellec district. The project’s scope also included the construction of four complex engineering structures, new multimodal hubs, and 12 kilometers of dedicated bicycle lanes to support integrated urban mobility.

Key Project Data

How Does This Compare to Similar Projects?

Brest’s project is a city-scale, multimodal infrastructure investment typical for medium-sized European cities seeking to integrate sustainable transport modes. Its scope contrasts with large-scale, national-level rolling stock procurements. For example, Comboios de Portugal awarded a €1.03 billion contract to Alstom in late 2025 for 153 new trains, the largest such acquisition in the country’s history, focused entirely on fleet modernization rather than new civil infrastructure (Source: Alstom SA, 2026). The Brest investment, while smaller, is more complex, involving civil engineering, urban redevelopment, and the integration of tram, bus, and cycling networks simultaneously.

Editor’s Analysis

Brest’s expansion consolidates its strategy of using integrated public transport as a tool for urban regeneration, particularly in the Bellevue and Lambézellec districts. However, the project’s long-term success in boosting ridership will depend on factors beyond the new infrastructure itself. Market trends from other developed networks show that simply adding lines does not guarantee growth; Metro Transit in the U.S. Twin Cities reported a 14% drop in light rail use in 2025 despite new BRT lines, citing public safety and fare policy as persistent challenges (Source: Axios, 2026). Brest’s ability to maintain a safe, reliable, and affordable service will be as critical as the new steel and concrete.

FAQ

Q: How many passengers are the new lines expected to carry?
A: The new tram line B and BRT line D are collectively designed to transport over 3.5 million passengers per year. This is in addition to the more than 12 million passengers carried annually by the existing tram line A.

Q: What was the total cost of the “My network is expanding” project?
A: The total investment value for the project was not disclosed in the official announcements. The project was awarded to the Mobi-Brest consortium in 2021 after a competitive bidding process.

Q: How do the new routes connect with Brest’s existing public transport?
A: Both the new tram line B and BRT line D originate from the area around the central SNCF train station. This provides a key interchange point with the original tram line A, which opened in 2012, creating an integrated, multimodal hub in the city center.
