The Alstom Metropolis is a family of electric multiple units designed and produced by the French rolling stock manufacturer Alstom. It is designed for high capacity rapid transit or metro rail infrastructure systems. Trains can be run in various configurations, the length alone varying between two and ten cars; it is also suitable for both manned or unmanned operations.

More than 4,000 Metropolis cars have been manufactured, the type is reportedly in service with 50 operators distributed around the world.{{cite web |url = https://www.railway-technology.com/projects/alstom-metropolis-trains/ |title = Alstom Metropolis Trains |publisher = railway-technology.com |access-date = 31 December 2020}} Cities operating the Metropolis include Singapore, Shanghai, Budapest, Warsaw, Nanjing, Montreal, Buenos Aires, São Paulo, Lima, Santiago, Barcelona, Guadalajara, Istanbul, Santo Domingo, Chennai, Kochi, Dubai, Lucknow, Sydney, Amsterdam, Xiamen, Hanoi, and Riyadh.

Design features

Alstom's Metropolis family of electric multiple units is highly adaptable; the basic body can significantly vary in size between small, medium and wide configurations to meet a variety of client's needs. A typical trainset is deployed in two to six car arrangement. The Metropolis has been designed to be both flexible and reliable, incorporating a high level of technology to do so. It has been designed for a maximum speed of up to {{convert|120|km/h|mph|abbr=on}}, which has been deemed to be sufficient for its use on mass transit systems. The propulsion system incorporates the ONIX (ONduleur à Intégration eXceptionnelle) or OPTONIX VVVF drive with IGBT transistors that control asynchronous three-phase alternating current (AC) traction motors. Amongst other abilities, this arrangement enables regenerative braking, reducing the train's energy consumption.

It can be configured to operate as part of an entirely automated driverless system, enabling the train to have unattended train operation (UTO) functionality. To achieve this, Alstom typically offers the Metropolis as one element of a complete turnkey system, including the trainset itself along with the signalling system, track works and services. Several operators have procured the train in such a configuration, including the Sydney Metro (Australia's first fully-automated rail network) and the Budapest Metro (the first automated metro line in Central-Eastern Europe).

The car body is highly adjustable, being composed either of aluminium or stainless steel, while the width can range from {{convert|2.30|-|3.2|m|ftin|frac=8|abbr=on}} and the length from {{convert|13|–|25|m|ftin|frac=8|abbr=on}}. It can be fitted with either steel wheels or rubber tyres, depending upon the customer's requirement. As standard, each Metropolis features a trainborne Ethernet backbone, providing resilient broadband communications for subsystems, including security apparatus, an optional public address system, and passenger information equipment; these are organised into integrated modules within the onboard security and communications subsystems. For ease of maintenance, the Metropolis is compatible with an internet-delivered TrainTracer tool, which monitors major components of each train and can display condition information in real-time to depots and operational control centres alike.

The interior can also be customised as per customer requirements. Optional features include closed-circuit television (CCTV), wider seats, additional grabpoles, more space around the doors, wheelchair space and equipped with electronic displays – the latter is typically used to depict journey information, safety messages and advertisements. The size of the doors can be customised along with the width of the gangways, while a modular seating arrangement is typically installed. A specialised glass named Climavit is used for the windows, it is supplied by the French manufacturer Sekurit Saint-Gobain; amongst its claimed benefits is a reduction in the typical internal noise level by five decibels.{{Citation needed|date=February 2008}}

Major deployments

During July 2006, OPRET signed an initial contract for the supply of 19 Metropolis trainsets to equip the first line of the Santo Domingo Metro with Alstom; these were configured to be nearly identical to the 9000 series on the Barcelona Metro save for the livery applied.{{cite journal | url=http://www.railwaygazette.com/news/single-view/view/city-news-5.html | title=City News July 2006 | journal=Railway Gazette International | date=1 July 2006 | access-date=1 April 2015}} In January 2011, an order was announced for a further 15 Alstom trainsets for Line 2.{{cite web |url=http://www.railwaygazette.com/nc/news/single-view/view/world-rolling-stock-market-january-2011.html |title=World rolling stock market January 2011 |date=7 January 2011 |access-date=1 April 2015}} During March 2012, the first trainsets for the second line were delivered to the operator.

Alstom secured a $253m (€200m) order in February 2010 from GVB for 23 six-car Type M5 Metropolis trainsets for the Amsterdam Metro. Three years later, this was followed by a supplemental order, valued at €42m ($53m), for five more trains. Each being configured to carry up to 1,000 passengers, they have replaced all of the legacy M1-M3 sets on the East Line as well as increased overall capacity, being used on all routes except Route 51.{{cite web |url=http://www.gvb.nl/overgvb/bedrijfsprofiel/MaterieelEnCijfers/Pages/nieuwemetro.aspx |title=Nieuwe metro: de M5 Metropolis (New Metro: the M5 Metropolis) |publisher=GVB |language=nl |access-date=1 August 2014 |url-status=dead |archive-url=https://web.archive.org/web/20140817015028/http://www.gvb.nl/overgvb/bedrijfsprofiel/MaterieelEnCijfers/Pages/nieuwemetro.aspx |archive-date=17 August 2014}}

During March 2012, Singapore's Land Transport Authority placed an order valued at $303m for the supply of 34 Metropolis trains, 18 of which were for the North East Line (NEL) while the remaining 16 were allocated to Circle Line (CCL). Furthermore, accompanying signalling upgrades for both of these lines was also included in the arrangement.{{cite web| url=http://app.lta.gov.sg/apps/news/page.aspx?c=2&id=5qmktlgi52sor9rc5r00c6xm8pg371lwhgx5hvtwu8381p6o95| title=LTA and SMRT Award Contracts for New Trains and Re-Signalling Project| date=1 February 2012| access-date=16 November 2013| publisher=Land Transport Authority| url-status=dead| archive-url=https://web.archive.org/web/20130929162504/http://app.lta.gov.sg/apps/news/page.aspx?c=2&id=5qmktlgi52sor9rc5r00c6xm8pg371lwhgx5hvtwu8381p6o95| archive-date=29 September 2013| df=dmy-all}}{{cite web| url=http://www.alstom.com/press-centre/2012/2/80885/| title=Alstom to supply 34 Metropolis trains and signaling upgrade to Singapore metro| date=3 February 2012| access-date=16 November 2013| url-status=dead| archive-url=https://web.archive.org/web/20131231010930/http://www.alstom.com/press-centre/2012/2/80885/| archive-date=31 December 2013| df=dmy-all}}

A total of 15 Metropolis trainsets were ordered for Hungary's Budapest Metro. During March 2014, operations of the type on the Metro's underground line four commenced, thus becoming the first automated metro line in Central-Eastern Europe.

In 2010, Alstrom secured a large order, valued at approximately $307m (€243m), to supply 42 train sets for Phase I of the Chennai Metro.{{cite press release |url=http://www.alstom.com/press-centre/2013/5/alstom-completes-in-lapa-plant-the-first-train-for-chennai-metro-in-india/ |title=Alstom completes in Lapa plant the first train for Chennai metro, in India |work=Alstom |date=May 2013 |access-date=6 June 2016}} The first nine trains were imported from Brazil and the remaining were manufactured at a new facility established at Sri City, Tada about {{convert|75|km}} from Chennai.{{cite news |url=http://www.thehindubusinessline.com/industry-and-economy/logistics/first-coach-for-chennai-metro-by-april-2013-alstom-transport/article3991494.ece |title=First coach for Chennai Metro by April 2013: Alstom Transport |newspaper=Business Line |access-date=6 June 2016}}{{cite news |last=Sekar |first=Sunitha |title=Chennai Metro to have 1st class compartment |newspaper=The Hindu |date=28 October 2013 |url=http://www.thehindu.com/news/cities/chennai/chennai-metro-to-have-1st-class-compartment/article5278833.ece |access-date=2 March 2014}} The trains are air-conditioned with electrically operated automatic sliding doors and a regenerative braking system.
