Alstom Completes 8.7-Mile Montreal REM Light Rail Branch
Alstom commissioned an 8.7-mile automated light-rail branch for Montreal’s Reseau express metropolitan (REM) network, expanding the driverless system to 40 miles and 23 stations.

MONTREAL, Canada – Alstom this month commissioned an 8.7-mile branch of the Reseau express metropolitan automated light-rail network, expanding Montreal’s rapid transit system. The newly inaugurated section connects Sainte-Anne-de-Bellevue on the Island of Montreal directly to the downtown core. This expansion increases the operational network to 40 miles and 23 active stations, utilizing a fleet of 212 automated rail cars.
What Is the Full Scope of This Project?
The newly commissioned 8.7-mile branch is a key phase of the Reseau express metropolitan (REM) network, which will ultimately span 42 miles and feature 26 stations. Alstom delivered the complete system, including 212 light-rail cars, signaling, and a digital predictive maintenance platform. Operations and maintenance are managed through a joint venture between Alstom and AtkinsRealis. Concurrently, Vossloh has commissioned an automated turnout plant in Sannahed, Sweden, featuring robotic tie installation to replace its legacy Orebro site. Separately, corporate filings indicate Alstom also commissioned an 8 MW wind turbine this month to expand its global sustainability portfolio (Source: Alstom, 2026).

How Does This Compare to Similar Projects?
The REM network represents one of the largest automated driverless light-rail systems globally, rivaling the scale of Vancouver’s SkyTrain. Vancouver’s SkyTrain currently spans approximately 49.5 miles, meaning Montreal’s REM will be nearly identical in size upon reaching its full 42-mile build-out (Source: TransLink, 2024). In terms of manufacturing automation, Vossloh’s new Sannahed plant—capable of producing 900 turnouts annually—modernizes supply chains in Sweden, where the broader railway signaling market is growing at a 6% CAGR from 2026 to 2033 (Source: Coherent Market Insights, 2024). Comparable cost data for the Sannahed plant construction was not publicly available at the time of publication.
Editor’s Analysis
The expansion of the REM network demonstrates the growing viability of fully automated, driverless light-rail systems as a preferred solution for mid-density urban corridors. By integrating predictive maintenance platforms and automated turnout manufacturing, operators are shifting from reactive maintenance to automated, data-driven lifecycle management. This modernization aligns with European initiatives, such as the EU Passenger Package, which aims to maximize rail capacity to meet regional transit and decarbonization goals (Source: European Commission, 2024).
FAQ
Q: What is the total length of the Montreal REM network once it is fully completed?
A: The REM network will span approximately 42 miles and feature 26 stations at full build-out. It will establish a direct transit link between downtown Montreal and Montreal-Trudeau International Airport.
Q: What technology is being used to manufacture rail turnouts for the Swedish network?
A: Vossloh’s new facility in Sannahed, Sweden, utilizes an automated assembly line equipped with robotic tie installation. This plant has a maximum production capacity of 900 turnouts per year.
Q: What is the financial value of Alstom’s REM contract and Vossloh’s new plant?
A: The specific financial values for the newly commissioned REM branch and Vossloh’s Sannahed facility were not publicly disclosed.
