The DT-1 trains used on Line U1, some of which date from the opening of the first phase of the 19km line in 1972, will be superseded by 21 four-car G-1 sets.
VAG says it is in negotiations with Siemens and is still working on the financial part of the contract, which has an estimated value of €164m.
Traditionally Nuremberg U-Bahn trains have been formed of articulated pairs of vehicles, but the G-1 will be the first four-car fully articulated train to run on the network and will be at least three tonnes lighter that paired two-car sets. "There were several key factors in this decision, including lower purchase price, significant energy savings during operation, and the sense of security a full-length train will give passengers," explains VAG technical director Mr Michael Richarz.
The G-1 has been developed on the basis of a design study by Munich-based agency ergon3Design, which was carried out in consultation with passengers with reduced mobility. The trains will be equipped with retractable steps, and multifunctional areas for pushchairs and wheelchairs.
The contract includes two options for additional trains. The first option comprises six trains, which would replace 12 DT-2 two-car sets, while the second comprises seven trains, which would be ordered to increase capacity on Line U1.
Tenders for the contract were launched in July 2014.
