The Montréal Metro rolling stock consists of 759 cars, all of which use rubber tires as opposed to steel wheels, similar to some lines in Paris. As a result, the Montréal rolling stock is modeled off of Paris's MP59 cars. The Montréal cars are not weatherproof because the entire system, including the yards and maintenance shops, are underground. In 2016, the driverless MPM-10 trains began entering service and will replace all the MR-63 trains by the end of 2018.
