Alstom and Hamburger Hochbahn sign framework contract for new metro trains

Alstom has signed a framework agreement with Hamburger Hochbahn AG worth up to EUR 2.8 billion. The contract covers the delivery of up to 374 new metro trains, for fully and semi-automated operation.

Alstom will also equip the 25 km long and fully automated new metro line U5 with the train-centric CBTC system Urbalis. The first call-off under this framework agreement comprises 48 metro trains and the CBTC equipment for the first section of the U5 line, including five of the 23 new metro stations. The call-off has a volume of around EUR 670 million.

90 second intervals

The framework agreement includes 254 semi-automated and 120 fully automated (GoA4) metro trains, all consisting of four cars. The metro trains score with their high capacity, passenger safety and comfort thanks to modern interior design, digital passenger guidance and USB charging connections. The fully automated trains are to be used on the line U5, which is currently under construction. The semi-automated trains will gradually replace the current DT4 vehicles and run semi-automated on parts of the existing network.

The U5 metro line will be fully equipped with the state-of-the-art Urbalis signalling solution for driverless operation. This will increase punctuality, frequency and energy efficiency. Once all 23 stations have been completed, the U5 can operate at 90 second intervals. This will enable around 270,000 passengers to be transported quickly and safely on the U5 every day.

The production of the new generation DT6 metros will take place at the Alstom site in Salzgitter, Germany, and is scheduled to start in 2026, with delivery of the first vehicles planned for early 2028. The start of passenger operation on the first section of the new line U5 is scheduled for 2029. The Alstom site in Berlin, Germany, is leading project execution of the digital rail segment, including signalling.

“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,” Müslüm Yakisan, President DACH region at Alstom has 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,” added Robert Henrich, CEO of Hamburger Hochbahn AG.
