I always like the (grease?) smell in Montréal Metro stations but never thought about it in terms of particulate matter concentrations.

I always like the (grease?) smell in Montréal Metro stations but never thought about it in terms of particulate matter concentrations.
- morkalork 3y agoUnfortunately the only smell I can associate with the Montréal metro is piss
- VK538FY 3y agoI understood that the Montreal metro trains used wood breaks and peanut oil. Hard to say if that makes the same mess, but the rubber tires surely leave something. Also, the new rames may use different breaking technology.
- lbourdages 3y agoThey initially used different brakes, but they reverted to the good old peanut oil brakes because they had issues of some sort with dust. I'm struggling to find a source that tells the reason, but here you can see they chose wooden brakes. https://www.stm.info/sites/all/modules/custom/stm_import/imported_files/a-%20FicheMPM-10maquette_12.pdf https://www.stm.info/sites/all/modules/custom/stm_import/imp...
