Réseau express métropolitain (REM)

The Réseau express métropolitain (REM) project is a fully automated, 100% electric metro transit system, made up of 67 km of dedicated rail lines in the Greater Montréal area. The REM, which more closely resembles a metro system than a commuter train, will serve high-frequency stations 20 hours a day, seven days a week.

The REM project will include four branches and 26 stations connecting downtown Montréal, the South Shore, the West Island, the North Shore and the airport, and will be connected to buses, two commuter train lines and three Montréal metro lines.

You can find more information on the REM project by visiting the following links:

Potential benefits:

  • Traffic congestion: Improve speed and traffic flow in highly congested sectors, reducing economic losses related to road congestion in the Greater Montréal area
  • Gross domestic product (GDP): Over $3.7 billion for Québec’s GDP
  • Sectors with high development potential: Close to $5 billion anticipated in private investments
  • Jobs: Creation of more than 34,000 direct and indirect jobs during the construction phase and more than 1,000 permanent jobs once the REM starts running
  • Productivity: Significant time savings for users

Main sustainability advantages

  • Increase in public transit use, and reduction in car use and the associated social costs
  • Decrease of nearly 680,000 tonnes in GHG emissions over 25 years
  • Significant reduction in noise levels, adverse visual impacts, and air pollution linked to the passing of cars
  • Contribution to the electrification of transportation and improvement of the sector’s energy efficiency, in order to develop the economy and reduce GHG emissions;
  • Contribution to the academic, professional and social integration of people with mobility impairments, thanks to universally accessible stations and cars

New AZUR Métro cars project

The project involves the Société de transport de Montréal’s (STM) acquisition of 54 AZUR trains (486 cars), 38 of which are to replace the 1963 métro cars (MR-63) and 16 are as additional ones. These new cars feature leading edge design and technology.


  • Improvement of the customers’ transit experience (quality of the information provided, comfort, ventilation, safety)
  • Expected gains in train enhanced performance and reliability
  • Contribution to the métro’s universal accessibility
  • Major beneficial economic impacts for Québec

Main sustainability advantages

Thanks to the AZUR cars, the STM aims to:

  • Reach 440 million public transit trips on the STM network by 2025
  • Increase electric-powered travel on its network from 69.5% to 88.6% in 2025
  • Reduce GHG emissions per passenger-kilometre by 6% between 2015 and 2025 (from 47.5 g of CO2 eq. per passenger-kilometre in 2015 to 44.7 g of CO2 eq. per passenger-kilometre in 2025)
  • Ensure reclamation of over 85% of the 8 200 tons of materials from the 333 MR-63 cars

Réno-Systèmes Project

The Réno-Systèmes program attends to the replacement, construction or refurbishment of the métro’s network operational stationary equipment:

  • Escalators, ventilation, elevators
  • Rail equipments and switches
  • Signaling and power supply equipment
  • Telecommunications and operational control systems


  • Improvement in the reliability, availability and safety of the métro’s network operational stationary equipment (fewer service outages)
  • Improvement in communications (public address system)
  • Improvement in response times in the event of a service outage
  • Improvement in universal accessibility

Réno-infrastructures Project

Réno-Infrastructures program attends to the replacement or refurbishment of the métro infrastructure while optimizing investments by using them as levers to improve the service quality and performance.

The métro infrastructure includes all stations, tunnels, auxiliary structures, as well as garages and workshops.


  • Maintain the condition and reliability of the infrastructure
  • Maintain the availability and safety of the métro network
  • Improve the universal accessibility
  • Restore several works of art

Hybrid bus purchase project

The purchase of 1,238 hybrid biodiesel-electric buses and 34 electric buses is a key element in the STM’s strategy toward electrification. Based on projections, the STM should hold a fleet of vehicles comprised entirely of hybrid and/or electric vehicles from 2029 onwards.


  • The customers’ transit experience is greatly improved with the rollout of these buses, as they are quieter, more comfortable and, depending on their configuration, provide air-conditioning.

Main sustainability advantages

  • Increase in the bus network’s passenger capacity with the addition of 534 hybrid or electric buses by 2020 (at that point their number should represent respectively about 37.5% and 1.8% of the overall fleet)
  • Increase in public transportation trips relying on electricity
  • Reduced GHG emissions per passenger-kilometre as biodiesel-electric hybrid buses burn up to 30% less fuel
