The '''Alstom Metropolis''' is a family of [[electric multiple unit]]s 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.<ref name="rail tech">{{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}}</ref> 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]], [[Paris]], 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.<ref name="rail tech" /> 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.<ref name="rail tech" /> The propulsion system incorporates the ONIX (ONduleur à Intégration eXceptionnelle) or OPTONIX [[Variable-frequency drive|VVVF drive]] with [[insulated-gate bipolar transistor|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.<ref name="rail tech" />

It can be configured to operate as part of an entirely automated driverless system, enabling the train to have unattended train operation (UTO) functionality.<ref name="rail tech" /> 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).<ref name="rail tech" />

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}}.<ref name="rail tech" /> 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.<ref name="rail tech" /> 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.<ref name="rail tech" />

The interior can also be customised as per customer requirements.<ref name="rail tech" /> 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 [[Modularity|modular]] seating arrangement is typically installed.<ref name="rail tech" /> A specialised glass named ''Climavit'' is used for the windows, it is supplied by the French manufacturer [[Saint-Gobain|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 [[Barcelona Metro 9000 Series|9000 series]] on the [[Barcelona Metro]] save for the livery applied.<ref>{{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 | archive-date=5 April 2015 | archive-url=https://web.archive.org/web/20150405192257/http://www.railwaygazette.com/news/single-view/view/city-news-5.html | url-status=dead }}</ref> In January 2011, an order was announced for a further 15 Alstom trainsets for Line 2.<ref>{{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 |archive-date=20 March 2012 |archive-url=https://web.archive.org/web/20120320160517/http://www.railwaygazette.com/nc/news/single-view/view/world-rolling-stock-market-january-2011.html |url-status=dead }}</ref> During March 2012, the first trainsets for the second line were delivered to the operator.<ref name="rail tech" />

Alstom secured a $253m (€200m) order in February 2010 from [[Gemeentelijk Vervoerbedrijf|GVB]] for 23 six-car Type [[M5 (Amsterdam Metro)|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.<ref name="rail tech" /> 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.<ref>{{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}}</ref>

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 MRT line|North East Line]] (NEL) while the remaining 16 were allocated to [[Circle MRT line|Circle Line]] (CCL). Furthermore, accompanying signalling upgrades for both of these lines was also included in the arrangement.<ref name="rail tech" /><ref>{{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}}</ref><ref>{{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}}</ref>

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.<ref name="rail tech" />

In 2010, Alstrom secured a large order, valued at approximately $307m (€243m), to supply 42 train sets for Phase I of the [[Chennai Metro]].<ref>{{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}}</ref> The first nine trains were imported from [[Brazil]] and the remaining were manufactured at a new facility established at [[Sri City]], [[Tada, Nellore district|Tada]] about {{convert|75|km}} from Chennai.<ref>{{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}}</ref><ref>{{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}}</ref> The trains are air-conditioned with electrically operated automatic sliding doors and a regenerative braking system.

During September 2014, Alstom was awarded a substantial contract to equip the [[Sydney Metro Northwest]], Australia's first fully-automated rail network. The deal involved the production and supply of 22 six-car Metropolis train sets, along with the [[communications-based train control]] (CBTC) signalling infrastructure to facilitate its automated operations.<ref name="rail tech" />

In November 2020, Alstom secured a contract to provide 20 driverless Metropolis trainsets for the [[Line 4 (Athens Metro)|Athens Metro Line 4]], due to open in 2028.<ref>{{Cite web |title=Alstom consortium selected for first section of Athens Metro Line 4 |url=https://www.alstom.com/press-releases-news/2020/11/alstom-consortium-selected-first-section-athens-metro-line-4 |access-date=2025-01-06 |website=Alstom |language=en}}</ref> During this time, Alstom also secured an order of 13 six-car Metropolis BM4 trains for use on [[Bucharest Metro]] line M5, for 100 million euros, which can be expanded up to 240 million euros for an extra 17 trains. These will also be equipped with Alstom's URBALIS 400 CBTC system onboard for STO operation.<ref>{{Cite web|url=https://www.alstom.com/press-releases-news/2020/11/alstom-provide-new-metropolis-trains-bucharest-metro-line-5|title = Alstom to provide new Metropolis trains for Bucharest Metro Line 5}}</ref>

In November 2021, the Egyptian National Authority for Tunnels  signed a contract with [[Alstom]] to supply 55 luxury air-conditioned Metropolis trains for [[Cairo Metro Line 1|the first line of the Greater]] [[Cairo Metro]]. Each train will consist of nine luxury cars, with delivery scheduled to begin in 2025.
 
The contract, valued at approximately €876 million, also includes long-term maintenance and technical support services, as well as localizing manufacturing at Alstom's new industrial complex in [[Borg El Arab|Borg El Arab, Alexandria]]. This deal is an extension of a long-standing cooperation between Egypt and Alstom and a trust that dates back to 1971.<ref>[https://www.alstom.com/press-releases-news/2021/11/alstom-awarded-egypts-largest-metro-rolling-stock-contract-improve], [https://www.alstom.com/press-releases-news/2021/11/alstom-awarded-egypts-largest-metro-rolling-stock-contract-improve Alstom awarded Egypt’s largest metro rolling stock contract to improve public transport within Cairo].</ref>
