Alstom to Supply Up to 374 Metro Trains and CBTC Signalling for Hamburg U-Bahn

Alstom and Hamburger Hochbahn have signed a framework contract valued at up to 2.8 billion EUR to supply new metro trains and CBTC signalling technology for the Hamburg U-Bahn.

Under this contract, Alstom will supply up to 374 new fully and semi-automated metro trains. In addition, it will provide its CBTC Urbalis signalling system for 25 kilometres of the city’s new fully-automated U5 metro line.

The first firm order for this agreement includes 48 metro trains and the CBTC equipment for the first section of the U5 line, encompassing five of the 23 new metro stations. This order has a value of 670 million EUR.

In total, the framework agreement encompasses 254 semi-automated and 120 fully automated metro trains, all consisting of four cars.

The fully automated trains will be used on the U5 line, which is currently under construction. The semi-automated trains will replace the current DT4 vehicles and run semi-automated on parts of the existing network.

Müslüm Yakisan, President DACH region at Alstom said:

“This contract is a milestone for Alstom. With the new metro trains and the equipping of the fully automated U5 line with innovative control and safety technology, Hamburg is meeting the growing demand for mobility and sending an international signal for digital and green mobility. All of Hamburg’s metro trains are from Alstom and we are delighted to be able to continue our successful collaboration with Hamburger Hochbahn, which goes back over 60 years. Passengers can look forward to new metro trains with modern passenger information systems, air conditioning, USB charging stations and panoramic windows.”

The new generation DT6 metros will be produced at the Alstom site in Salzgitter, Germany from 2026. The delivery of the first vehicles is planned for early 2028.

Meanwhile, the Alstom site in Berlin, Germany, is leading the project execution of the digital rail segment, including signalling.

Robert Henrich, CEO of Hamburger Hochbahn AG said:

“With the new vehicles, we are modernising our fleet and creating the conditions for fully automatic operation on the U5. The new DT6 will offer customers a completely new experience – from the interior design, transparency and brightness to the modern information systems that provide passengers with optimum orientation. All to the highest technical standard. At the same time, the new subway trains will shape Hamburg's cityscape like no other vehicle.”

The start of passenger operation on the first section of the new U5 line is scheduled for 2029.

Once all 23 stations have been equipped with the CBTC signalling technology, trains on the U5 line will be able to operate at 90-second intervals, enabling around 270,000 passengers to be transported quickly and safely each day.
