The MPM-10 (Montréal Pneumatic Material 2010), also known as the Azur, is a fleet of subway trains being built by Bombardier Transportation for the Montreal Metro. A test train was delivered in 2014 and they are expected to replace the aging MR-63 trains beginning in 2015.

History

In May 2006, the Government of Quebec announced the negotiation of a $1.2 billion contract to replace the MR-63 fleet of 336 cars. Alstom voiced its dismay over directly awarding the contract (to Bombardier) without a bidding process. Negotiations between the STM and Bombardier were to be ongoing until 2007. The negotiations focused on the project's cost controls, terms of contract, train specifications and warranty. If negotiations had failed, the Quebec government and the STM would have reverted to a bidding process.

On January 10, 2008, Quebec Superior Court Judge Joel Silcoff rendered his decision regarding Alstom's filing of legal action against the Quebec government's ministry of transportation. The latter sought to by-pass the bidding process, citing that Bombardier was the only domestic candidate capable of fulfilling the eventual contract. Silcoff ruled in favour of Alstom, enabling the company to bid on the contract.

As of February 6, 2008, the Government of Quebec decided to begin the bidding process, which would serve to save time, delaying delivery of the first trains by 9 to 12 months.

In October 2010, the Quebec government officially gave the contract to the Bombardier-Alstom consortium, valued at CA$1.2 billion. Bombardier expected the new cars to begin entering revenue service by February 2014, with deliveries continuing through 2018.[1][2] In May 2013, the STM finished preparing the tunnels for to the reception of the first test train. This work included grinding some concrete on 200m of tunnels, where lasers measurements indicated that some scraping might have occurred, due to the new trains' softer suspension.[3] The first prototype train was unveiled in late 2013, and was delivered in April 2014.[4] Tests of the prototype revealed several incompatibilities with Montréal's infrastructure, including insufficient electrical power. In January 2015 Bombardier suspended production for six months because of delays with the completion of the automated train control software .[5]

Specifications

The 468 new cars, arranged in 52 nine-car sets, will feature full-width walkways between the cars which can be occupied by passengers, resulting in higher train capacities.[6] They will also be equipped with an air suspension system, larger windows and doors, and wheelchair spaces, although the vast majority of Metro stations are not wheelchair-accessible yet. They will also feature more natural lighting, high definition televisions, a new PA system and surveillance cameras.[7] News reports also suggest that the new rubber-tire train will have to meet very demanding performance requirements: powerful acceleration, high-speed gradeability, high-performance brakes, good ride comfort, low noise, low maintenance costs, low energy costs and high levels of reliability. The new MPM-10 trains will however maintain the same maximum speed as the current MR-63 and MR-73 trains, 72.4 km/h (45.0 mph). Improving on the performance levels of the current fleet and developing new rolling-stock capable of using sheer speed as a means of increasing line capacity will represent a major challenge to Bombardier and Alstom. The STM have mentioned that the trains are going to be heavier than the outgoing MR63s, due to the train's ability to carry more people.[8][9]
