The MR-63 is the first and oldest EMU rapid transit train type operated on the Montreal Metro in the city of Montreal, Quebec, Canada.
Based on the Paris Métro's MP 59 rolling stock, the MR-63 were constructed by Canadian Vickers from 1965–1967 and was introduced on October 14, 1966 on the opening of the Montreal Metro, and are still in service. During this time the fleet has undergone numerous technological and reliability upgrades, starting with the introduction of Automatic Train Control in 1976 (with subsequent revisions of hardware and software), major refurbishments of the MR-63 coaches by GEC Alsthom at Pointe St. Charles workshops in 1993, solid-state door interlocks in 2003, modern ergonomic driver cabs with new digital dashboards, and automatic station announcements in 2005 (voiced by Michèle Deslauriers).
The MR-63 is identified with grey interiors, four ventilation hoods protruding over the roof of each car, two 113 kW (152 hp) 360-V series traction motors that make a whining noise, and round cab headlights. Montreal's rolling stock is among the oldest still in use on any metro system in the world, though for comparison the New York City Subway's R32s are even older and still in revenue service as of April 2017. In the early 1970s, one 9-car trainset, consisting of three trains in 3-car formation, had their traction systems replaced with a prototype for a chopper traction system manufactured by the Canron company using a Jeumont original design. Trains utilizing the current chopper system produce an unusually loud 5-tone chorus as the train begins its initial acceleration out of the station. The frequencies used (90 Hz, 120 Hz, 180 Hz, 240 Hz, and 360 Hz) just so happen to produce a musically appealing sound that was later incorporated, by popular demand, into the 3-tone door closing chimes of the later MR-73 trains. Two of the three 3-car prototype trains are still in service (one train is much louder than the other), while the other 3-car prototype train was subsequently retired from service and is now used as part of the Just for Laughs festival.
