The '''MR-63''' (Matériel roulant 1963) was the first generation of rubber-tyred rolling stock of the Montreal Metro in the city of Montreal, Quebec, Canada. Based on the MP 59 of the Paris Métro in France, the trains were in use on three of Montreal's four Metro lines from 1966 until 2018. By the time of their withdrawal, the trains were among the oldest still in use on any metro system in North America, at 52 years old.

== History == left|thumb|Initial concept design of the trains As part of the development of the Montreal Metro in the early 1960s, the City of Montreal was assisted in the detailed design and engineering of the Metro by French consultant SOFRETU, owned by the operator of the Paris Métro.<ref name=":1">{{Cite news |date=1982-02-09 |title=LES PROJETS DE LA SOFRETU |language=fr |work=Le Monde.fr |url=https://www.lemonde.fr/archives/article/1982/02/09/les-projets-de-la-sofretu_2886786_1819218.html |access-date=2023-08-21}}</ref> It was decided that the new Metro would use a similar rubber-tired train design as used on the Paris Métro – instead of steel ones as used on the Toronto subway.<ref>{{Cite web |last=Magder |first=Jason |date=13 Oct 2016 |title=The métro at 50: Building the network |url=https://montrealgazette.com/news/local-news/the-metro-at-50-building-the-network |access-date=14 Sep 2023 |website=Montreal Gazette |quote=The idea for tires came to Drapeau and Saulnier when they visited Paris, the first subway system to incorporate tires to address a problem of overcrowding.

A large number of rolling stock manufacturers were expected to bid for the rolling stock contract, with French firms expected to have an advantage due to the Paris Métro design.<ref>{{Cite news |date=20 July 1963 |title=Montreal hopes haggling will cut Subway car cost |pages=5 |work=The Financial Post |quote=European as well as North American builders of rolling stock were expected to bid for the contract.

After negotiations with both MLW and Canadian Vickers, the Commission de transport de Montréal (CTM) awarded the MR-63 contract to Canadian Vickers in August 1963, at a cost of $45 million.<ref>{{Cite news |last=Negru |first=Myer |date=7 August 1967 |title=Extensions For Subway Approved |pages=3 |work=Montreal Gazette |quote=Contract for the rolling stock – covering design, manufacturer, delivery of 369 subway cars, spare parts and five tractors for work trains – went to Canadian Vickers Ltd., lower of two private tenderers at $45,513,918.}}</ref>

=== Production and entry into service === The cars were built at the Canadian Vickers shipyards in the Viauville neighbourhood of the Mercier–Hochelaga-Maisonneuve borough of Montreal, designed by Morley L.

In 1976, automatic train operation was introduced.

== Design == The cars were made of a lightweight steel alloy, {{Convert|2.5|m|sp=us}} wide by {{Convert|16|m|ftin|sp=us}} long and with four double sliding doors on each side. Each car had 40 seats, with a maximum load of 160 passengers per car. The trains run in three car sets, formed of two motor cars with a trailer in-between them. The 369 cars could be formed as a combination of 3, 6 or 9-car trainsets.<ref name=":6">{{Cite web |title=MR-63 Specifications |url=https://www.stm.info/sites/default/files/pdf/en/a-fiche_technique.pdf |access-date=14 Sep 2023 |website=Société de transport de Montréal}}</ref> The MR-63 was identified with grey interiors, four ventilation hoods protruding over the roof of each car, two {{convert|113|kW|hp|abbr=on}} 360-V series traction motors that make a whining noise, and round cab headlights.<ref name=":6" />

The industrial design of the train was undertaken by Jacques Guillon in 1963.<ref name=":4" /><ref name=":7" /> The colour of the train was a contentious decision, with Mayor of Montreal Jean Drapeau preferring the traditional white and red of the City of Montréal,<ref name=":4" /> with Guillon arguing for light blue with a white stripe, the traditional colours of Quebec.<ref>{{Cite book |last=Martins-Manteiga |first=John |title=le design en mouvement / Métro: design in motion |publisher=Dominion Modern |year=2011 |isbn=9780968193341 |pages=90–94}}</ref> Eventually, a baby blue colour was chosen, which "matched Lucien L'Allier's wife’s sweater”.<ref name=":4" />

=== Motor design === The MR-63 model uses a series-to-parallel servo camshaft rheostat to control and regulate power to its traction motors; this control system can be heard tapping under the floor of a motor car as the train undergoes rapid acceleration at an initial rate of {{convert|1.33|m/s2|ft/s2|abbr=on}} ({{convert|4.8|km/h/s|mph/s|abbr=on|disp=or}}).<ref name=":6" /> This control system also features a dynamic rheostatic braking mode that uses the motors to slow the train, turning the motors into generators and dissipating the resulting energy as heat in the rheostat grid.

=== Hitachi and Jeumont prototype trains ===

In the early 1970s, two separate three-car trainsets had their original traction systems replaced with two chopper prototype traction systems, one manufactured by Hitachi (fitted onto elements 10, 11 and 12), and another manufactured by the Canron company based on a Jeumont original design (fitted onto elements 40, 41 and 42). The Hitachi chopper system fitted onto elements 10, 11 and 12 were subsequently changed back into their original traction systems a few years later. Jeumont elements 41 and 42 were however stored out of service until 2005 when they returned as trailer cars attached to other motor cars, where they remained in service until 2017, when they were retired alongside other MR-63s being replaced by MPM-10 trains. Jeumont element 40 was retired from service earlier than elements 41 and 42 because it needed to be cannibalised for spare parts for elements 41 and 42 that were no longer being manufactured. Jeumont element 40 has since then been used as part of the Just for Laughs festival.<ref>{{cite web |title=Station Chantilly :: Logique Floue |url=http://www.logiquefloue.ca/metro/train-jeumont/station-chantilly/ |access-date=2013-02-14 |website=www.logiquefloue.ca}}</ref>

== Reliability ==

Maintenance of Montreal's subway cars is rigorous, as reliability levels (Mean Distance Between Failures/MDBF ratings) are more than double that of typical North American subway cars by North American standards (at {{convert|200,000|km|mi|sigfig=4|abbr=on|disp=or}} in 2004). Furthermore, the entire metro is underground, with trains stored under cover at all times.<ref name=":0" />

In later years, obsolete components and parts availability meant the trains gradually became less reliable, and ride quality deteriorated as suspension systems and rubber spring packs hardened with age. Poor ride quality was not attributed to the tires or tracks.<ref name=":0" /> By the time of their withdrawal in 2018, Montreal's rolling stock were among the oldest still in use on any metro system in North America, at 52 years old.<ref>{{cite web |date=January 31, 2011 |title=Goodbye, retro Métro |url=http://www.macleans.ca/culture/goodbye-retro-metro/ |access-date=June 23, 2017 |work=Maclean's}}</ref>

== Accidents and incidents == * In July 1967, a train operator fainted at the controls of an MR-63 train, causing it to collide with the end wall of the Yellow Line terminus. The incident was attributed to excessive heat buildup in the cab, caused by the train's heaters combined with inadequate airflow from the forced-air ventilation system mounted on the roof. In response, air conditioning was installed in all MR-63 operator cabs, and the passenger cabin ventilation systems were modified to improve airflow. * On December 8, 1971, a speeding MR-63 train crashed into a parked MR-63 train near Henri-Bourassa station on the Orange Line, causing a 17-hour inferno that destroyed 24 MR-63 coaches parked at the Henri-Bourassa tail tracks. 40-year-old train operator Gerard Maccarone was the sole fatality in this accident, which was later revealed to be caused by a jammed throttle that prevented the train from braking in time. This was at that time the deadliest subway accident ever to have occurred in Canada until the Russell Hill subway accident on the Toronto subway in 1995.<ref>{{cite AV media | url = http://www.cbc.ca/archives/entry/fire-hits-the-montreal-metro |archive-url=https://web.archive.org/web/20160824211023/http://www.cbc.ca/archives/entry/fire-hits-the-montreal-metro |archive-date=2016-08-24 |title=Fire hits the Montreal metro |work=CBC News |date=December 10, 1971 |first=David |last=Halton}}</ref> * On January 9, 1974, a series of tire blowouts on a 9-car MR-63 train led to a fire which occurred between Laurier and Rosemont stations on the Orange Line. No deaths resulted from the fire, although the train was completely destroyed.
