"The REM is an automated light rail system, which is a quieter technology than the heavy exo trains that used to run on the Deux-Montagnes line. Nevertheless, sound modelling of the REM while in operation was carried out to assess its noise impact in the areas it runs through. [...] The sound modelling identified four specific areas where noise barriers need to be installed prior to commissioning the REM, enabling it to meet the requirements of the environmental decree issued by the Québec government."
