The Siemens Modular Metro is a family of electric multiple unit trains for rapid transit systems produced by 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 has been renamed Siemens Mobility, still uses the abbreviation Mo.Mo;[2][3] however, these trains are no longer being made, having been replaced by Siemens's new Inspiro family of metro trainsets.


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 steel or aluminium construction is available, in three cross sections: straight sidewalls, sidewalls sloping at 3 degrees, and contoured.[1]


  • Bangkok MRT Blue Line: each train consists of two motor cars and a centre trailer car.[4]
  • 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.[7]

Design Origins

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, but now also used in Nuremberg.
