The VAG Class DT1 (colloquially called "Pegnitzpfeil"[1]) is an electric multiple unit (EMU) train type operated by the Verkehrs-Aktiengesellschaft Nürnberg on the Nuremberg U-Bahn system since its opening in 1972. It is a derivative of the MVG Class A, in service on the Munich U-Bahn since 1971.[2][3]
Every DT1 train consists of two permanently-coupled cars, forming a twin-unit. The trains are equipped with automatic couplers, enabling operation of up to two units together to form a four-car train.[2]

Seating accommodation consists of transverse seating bays. Passengers can look into the adjacent car through two windows in the inner car end.[2]
The design is derived from the MVG Class A. Differences include a magnetic track brake system, that is missing from Munich's Class A trains.[3][2] The car bodies are made out of aluminium, and the trains are powered by direct current motors. Beginning with units 465/466, built from 1980 until the end of production in 1984, the trains were delivered with three-phase motors.[2] Besides the power supply by contact shoes, every unit is also equipped with a pantograph, as parts of the maintenance facilities are electrified with overhead lines.[2][1]
The trains were built from 1970 until 1984,[2] and entered passenger service on March 1, 1972, together with the official opening of the Nuremberg U-Bahn system.[4] DT1 units were lent to Munich on two occasions, were they operated on the Munich U-Bahn system.[3] They were in service in Munich in 1972, which had a shortage of rolling stock during the 1972 Summer Olympics and in 1980, during the visit of Pope John Paul II.[2] Following their service in Munich, units 401/402, 403/404, 409/410, 423/424, 425/426 and 427/428 carried commemorative stickers with the Munich Coat of Arms next to the doors of the driving cabs.[3]
Twelve sets were scrapped in 2010.[5][6] The DT1 trains have since been replaced by new VAG Class G1 trains, which entered service in mid-2019.[7] One DT1 train will be preserved.[5][6]
