The SL C20 is a type of subway train used in the Stockholm metro, Sweden. Between 1997 and 2004, 271 3-car sets, numbered 2000–2270, were delivered to Stockholm by the former Kalmar Verkstad, owned by Adtranz, later acquired by Bombardier Transportation. The C20 is a completely new design and therefore is not compatible with other train types in the system. At 46.5 metres, each carriage is longer than the previous train types. To save cost and weight, each unit has only four bogies. The middle car has two bogies. The end parts consist of one bogie each and are connected to the central portion via a semi-trailer-direction. Trolley subframes are made of stainless steel, and are less susceptible to corrosion.

Adtranz was a multi-national rail transportation equipment manufacturer with facilities concentrated in Europe and the US. The company, legally known as ABB Daimler-Benz Transportation, was created in 1996 as a joint venture between ABB and Daimler-Benz to combine their rail equipment manufacturing operations. In 1999, DaimlerChrysler bought ABB's shares and changed the company's official name to DaimlerChrysler Rail Systems. The company was acquired by Bombardier in 2001, which merged it into its Bombardier Transportation division, which became the largest rail equipment manufacturer in the world at the time, and was ultimately acquired by Alstom in 2021.
