The Alstom Movia (introduced as the Adtranz Movia and later sold as the Bombardier Movia) is a family of metro train cars designed by Adtranz and later built by Bombardier Transportation and Alstom. 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 by Adtranz, which was acquired by Bombardier in 2001. Since Alstom'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), and Shenzhen Metro (Line 1) all use Movia 456 trains, while Bucharest Metro (Line M1, M3, M5) use the Movia 346. Movia tube and sub-surface stock are in service on the London Underground (designated S Stock on the Circle, District, Hammersmith & City and Metropolitan lines and 2009 Stock on the Victoria line), Toronto subway (designated Toronto Rocket on Line 1 Yonge–University and Line 4 Sheppard), Bay Area Rapid Transit (designated D and E series) and Delhi Metro (Phase II only). Singapore MRT's North South and East West lines ordered 106 R151 Movia trains, one of the largest orders in Singapore.

The Movia is designed around a modular approach, which allows it to be adapted for use across a broad range of applications.[3] While developed as a standardised 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 and closed-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,[lower-alpha 1] FLEXX Metro 2000,[lower-alpha 2] FLEXX Metro 3000 or FLEXX Eco[lower-alpha 4] lightweight bogies, which reportedly enable optimum usage of vehicle capacity with less energy consumption. Other features of note include strong steering performance.[3]
