The Siemens Modular Metro is a family of electric multiple unit trains for rapid transit systems produced by Siemens Mobility (originally Siemens Transportation Systems) and used by rail operators around the world. The vehicle concept was launched in Vienna in 2000 and is a modular concept allowing many variants of metro vehicles.^[1] Previously known as Modular Mobility, Siemens, whose rail equipment division had since been renamed Siemens Mobility, still uses the abbreviation Mo.Mo;^[2][3] however, very little more of these trains are being built, since Siemens had moved to their Inspiro metro platform in 2013.

The train is designed for use on systems in the 20,000 to 60,000 passengers/hour range. The design of the train bodies is by Porsche Design. Modules in the system include various vehicle ends, doors, gangways, roof-mounted air-conditioning, and interiors.^[1] Many combinations of motor cars and trailers are possible, with individual vehicle lengths from 17 to 25 metres (55 ft 9 in to 82 ft 0 in) and widths from 2.6 to 3.2 metres (8 ft 6 in to 10 ft 6 in). Stainless steeloraluminium construction is available, in three cross sections: straight sidewalls, sidewalls sloping at 3 degrees, and contoured.^[1]

• Guangzhou Metro: 21 six-car modular trains which build with Adtranz for line 1, 120 cars which is based on it for line 3.
• Bangkok Transit System Skytrain: 57 4-car sets (22 of which built by a consortium with Bozankaya)
• Taipei Metro, Taiwan: 36 C321 and 6 C341 six-car sets for the Blue line
• Vienna U-Bahn: designated as Type V, 6-car units.
• Shanghai Metro: 28 six-car modular trains for Line 4, 10 trains for an extension of Line 1. First two trains in Vienna, remainder built in China.^[4]
• Metro Trains Melbourne: 72 3-car trains locally designated as Siemens Nexas.^[5] Use a broad track gauge of 1,600 mm (5 ft 3 in).

The bodies of the trains evolved from the 1993 DT2 Series used in the Nuremberg U-Bahn whose design in turn came from production of the A Series built for the nearby Munich U-Bahn.
