Canada is considered to have a highly advanced infrastructure, ranking among the best globally. This strong foundation makes the country an appealing hub for businesses, technological advancements, and international trade. A major priority is enhancing public transportation networks and improving passenger mobility, all while actively working to lower greenhouse gas (GHG) emissions. ABB is advancing sustainable transportation with cutting-edge electrification solutions in the Réseau express métropolitain (REM) project, one of Quebec’s most significant public transportation projects in 50 years.

The REM: A Landmark Sustainable Rail Project

The REM is a fully automated, electric light rail network designed to enhance public transportation in Greater Montreal. Once completed, this 67-kilometer network with 26 stations will connect key urban hubs, including Downtown Montreal, South Shore, West Island, Montréal-Trudeau International Airport

By serving an estimated 150,000 daily passengers, the REM is projected to cut greenhouse gas emissions by 2.5 million tons over 25 years, significantly advancing Canada’s clean energy goals.

Overcoming environmental and infrastructure challenges with ABB's expertise

In Canada, the transportation sector as a whole is responsible for 28 percent of Canada's total greenhouse gas emissions. Out of 49,422 kilometers of the country’s rail network, less than one percent, is electrified.

One of the REM’s most complex engineering challenges was integrating the South Shore branch with the Samuel-De Champlain Bridge, a structure exposed to extreme temperature fluctuations from +30°C to -30°C. ABB developed a custom expansion joint system to accommodate up to 27 inches (70 cm) of movement, ensuring seamless operation across all weather conditions.
