The VAG Class DT3 is an electric multiple unit (EMU) train type operated by the Verkehrs-Aktiengesellschaft Nürnberg on the Nuremberg U-Bahn system. It is the first type of rolling stock on the Nuremberg U-Bahn that has gangways between the individual cars.[1]

Formation

Every DT3 train consists of two permanently coupled cars, forming a twin-unit. The cars are connected with a gangway, allowing passengers to walk into the adjacent car. The trains are equipped with automatic couplers, enabling operation of up to two units together to form a four-car train.[1]

Interior

Seating accommodation consists of transverse seating bays as well as folding seats. The trains have displays which show the name of the next station, and CCTV cameras.[1] Passenger information screens and a passenger counting system are implemented in the DT3-F trains.[2] [3]

Technical specifications

The car bodies are made out of aluminium, and the trains are powered by three-phase-asynchronous motors.[1] As they are used in automatic operation, the DT3 trains are not equipped with full driving cabs, but only with small concealed driving panels, which are used for maintenance.[4] The DT3-F trains are equipped with full driving cabs, enabling them to be used on driver operated services on non-automated lines. The cabs are designed to be removed in case of a conversion for fully automated operation.[5] 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.[1]

History

The first unit was delivered in April 2004 as part of the "Rubin" project, which planned to introduce fully automated trains on the Nuremberg U-Bahn.[4] [1] Rubin is an acronym for Realisierung einer automatisierten U-Bahn in Nürnberg (Implementation of an automated U-Bahn in Nuremberg).[6] [7] Automated test running on line U3 began in January 2005.[4] [1] On May 4, 2008, the first DT3 trains entered automatic revenue service on line U3.[6] Driverless operation was officially launched on June 14, 2008, two years later than anticipated.[8] [9] Originally scheduled for 2006, the official launch of driverless operation had to be pushed back to 2008 due to technical difficulties[10] and mechanical problems, which resulted in the return of two prototype DT3 sets to the supplier Siemens.[11] Fully automatic trial runs on line U2 began on January 13, 2009, while the trains were already in automatic revenue service on line U3.[12]

DT3-F

A second batch of 14 DT3 trains was ordered in 2008.[13] These units, classified as DT3-F, feature a full control cab for manual operation, but also can be operated fully automatic.[13] First DT3-F units arrived in Nuremberg at the end of August 2010.[5] The DT3-F trains entered service in May 2011.[14] The "F" in the designation indicates the option of manual operation and means "Fahrer" (German for "driver").
