METRO operator Hamburger Hochbahn has signed a framework contract with Alstom worth up to €2.8bn to supply new trains and CBTC equipment.

The contract, awarded following a tender launched in 2018, covers the supply of up to 374 four-car trains, as well as the Urbalis CBTC system for Hamburg’s fully-automated 25km Line U5 that is currently under construction.

Designated DT6 by the operator, 254 of the new trains will be equipped for semi-automatic operation and known as Type F, with the remaining 120 Type A trains equipped for operation at Grade of Automation 4 (GoA4), enabling driverless operation at headways of 1min 30 sec.

Type A trains will operate exclusively on Line U5. Type F trains will gradually replace the DT4 fleet and run semi-automated on sections of the existing network.

In a first call-off worth around €670m, Alstom will supply 41 Type F trains and seven Type A trains, plus CBTC equipment for the first section of Line U5, including five of its 23 metro stations.

The 40m long, 2.73m wide high-capacity metro trains, fitted with digital passenger information systems, air-conditioning and USB charging points, are expected carry 270,000 passengers each day when Line U5 is completed. Up to three trains can work in multiple, carrying around 850 passengers in total.

The DT6 trains will be built at Alstom’s plant in Salzgitter, Germany, with construction scheduled to start in 2026, and delivery of the first trains expected in early 2028. The start of passenger operation on the first section of Line U5 is scheduled for 2029. Alstom’s Berlin facility will lead project management of CBTC installation.

"This contract is a milestone for Alstom,” says Mr Müslüm Yakisan, president of the Germany, Austria and Switzerland (DACH) region at Alstom.

“With the new metro trains and the equipping of the fully-automated Line U5 with innovative control and safety technology, Hamburg is meeting the growing demand for mobility and sending an international signal for digital and green mobility."

 “With this contract, we are laying the foundation for the growth of the Hamburg metro in the coming decades,” says Ms Anjes Tjarks, Hamburg senator for transport and mobility transition.

“At the end of 2018, the metro had around 250 trains in operation, currently there are 290. The contract will enable Hamburg to increase the number of metro trains by around 50%. This is a real quantum leap for mobility transition and sustainable transport.”

Change of supplier

In 2022 Hamburger Hochbahn awarded Siemens a contract to install CBTC on the entire 13.7km Line U4 and on Line U2 from its eastern terminus of Mümmelmannsberg via the city centre to Christuskirche, which shares infrastructure with U4 from Billstedt to the city centre.

Installation of CBTC on these lines, costed at around €200m and due for completion in 2029, will enable semi-automatic operation at GoA2 and will facilitate a reduction in headways to 1min 40 sec.
