TheAlstom Movia (introduced as theAdtranz Movia and later sold as theBombardier Movia) is a family ofmetro train cars designed byAdtranz and later built byBombardier Transportation andAlstom. The structure and body shell are fully customisable for the needs of each system that orders it. Unlike most traditional metro trains, they usually have full-width gangways between carriages, allowing passengers to walk the entire length of the train. The design was developed byAdtranz, which was acquired by Bombardier in 2001. SinceAlstom's acquisition of Bombardier in 2021, Alstom will be responsible for construction and delivery of future Movia metro train cars.[1]
Guangzhou Metro (Lines 1 and 8),Shanghai Metro (Line 9), andShenzhen Metro (Line 1) all use Movia 456 trains, whileBucharest Metro (Line M1, M3, M5) use the Movia 346. Movia tube and sub-surface stock are in service on theLondon Underground (designatedS Stock on theCircle,District,Hammersmith & City andMetropolitan lines and2009 Stock on theVictoria line),Toronto subway (designatedToronto Rocket onLine 1 Yonge–University andLine 4 Sheppard),Bay Area Rapid Transit (designated D and E series) andDelhi Metro (Phase II only).Singapore MRT's North South and East West lines ordered 106R151 Movia trains, one of the largest orders in Singapore. TheNew York City Subway ordered 73R179 cars, consisting of 47 4-car sets and 26 5-car sets.

The Movia is designed around amodular approach, which allows it to be adapted for use across a broad range of applications.[3] While developed as astandardised platform, both the structure and carriage bodies of the train are able to be extensively modified to conform with the varied requirements of a given operator. Reportedly, the Movia can be modified to better suit local operational conditions, while the train's steering and management system is easily accessible for periodic maintenance. Reduced operating costs have been achieved via the careful designing of the train carriages to readily facilitate access for maintenance and repairs, as well as for low lifecycle costs and with concern for environmental conditions.[3]
The Movia incorporates either a stainless steel or aluminium body, and an innovative propulsion system.[3] Each carriage is outfitted with relatively modern passenger information systems andclosed-circuit television (CCTV) systems. They feature modern interiors and exterior design; for favourable accessibility, they are normally furnished with both wide doors and spacious gangways.[3] The carriages are also outfitted to provide relatively low interior noise levels, resulting in an improved environment for passengers.[3]
The Movia train is powered by an advanced propulsion system, which is credited with achieving relatively low energy consumption, known as the MITrac (Modular Integrated Traction system).[3] This propulsion and control system is capable of vehicles using 600 V–3 kV DC, 15–25 kV AC and diesel electric propulsion. In a typical configuration, the train is capable of achieving a maximum operational speed of 85 km/h (53 mph).[3] Each carriage is outfitted with FLEXX Metro 1000,[a] FLEXX Metro 2000,[b] FLEXX Metro 3000 or FLEXX Eco[d] lightweightbogies, which reportedly enable optimum usage of vehicle capacity with less energy consumption. Other features of note include strong steering performance.[3]
