Alstom / Bombardier trains for Hamburger Hochbahn


Saint Ouen Cedex, France – 2006-12-14 the Hamburger HOCHBAHN AG (HOCHBAHN) has awarded a contract to a consortium of ALSTOM Transport and Bombardier Transportation for the delivery of a new generation of underground trains type DT5. The contract includes the delivery of 27 trains from 2009 to 2013 as well as an option of a minimum of 40 additional vehicles. The contract totals 240 million euros, including the options of 40 trains. ALSTOM´s share being 123 million euros, Bombardier´s share is valued at 117 million euros.

The scope of the Salzgitter-based consortium leader includes the delivery of the mechanical part, the bogies and the brake system. Bombardier Transportation is going to supply the electrical equipment from its sites Hennigsdorf and Mannheim.

“We are pleased to deliver the new generation with state-of-the-art technology and to contribute to a sustainable and environment-friendly mobility for the citizens of Hamburg,” said Andreas Knitter, Managing Director of ALSTOM in Salzgitter.

“The dependable consortium has previously delivered the successful DT4 predecessor generation,“ says Ulrich Sieg of the Management Board of the HOCHBAHN. “I’m convinced that the excellent cooperation between ALSTOM/Bombardier and the HOCHBAHN will again guarantee a smooth operation.“

Klaus Baur, Chairman of the Board of Bombardier Transportation Germany, said: „With this new metro for the future HafenCity, our consortium will deliver a first-class product for one of Europe’s most modern urban centers. We’re proud of Hamburger Hochbahn’s vote of confidence in our products for this new project."

For the first time, the three-unit underground trains feature open gangways, allowing passengers to move freely from one end of the train to the other. They will
successively replace the vehicles of type DT3 that had been manufactured by a consortium under the leadership of ALSTOM in Salzgitter between 1966 and 1971.

As of autumn 2011, one part of the DT5 fleet will be used principally on a new connection between the emerging quarter ‘HafenCity’ and Hamburg’s city centre. The “City Line“ U4 will connect the future city area (which is going to be built from 2007 as part of the biggest city development project in Europe) with the city centre in three minutes.

Increased passenger comfort through new interior fittings, as well as improved safety equipment of the vehicles should entice more and more automobile drivers to change over to public mass transport. The trendsetting interior design is characterized by full air conditioning, multi-purpose areas for wheelchair users and prams as well as a modern passenger information system with large LCD displays. A proven fire protection sprinkler system greatly enhances the safety of the passengers and the train drivers. Due to the use of stainless steel and new manufacturing technologies for the carbodies, the exterior walls can be easily cleaned and supersede extensive paintings. The manufacturers will also further improve the already exemplary ecological standard of the vehicles. Besides a high recycling rate of the used materials, the trains will be noise-optimized. In spite of additional equipment, such as the air conditioning system, they will reach the same low noise level as their predecessor generation which is among the most silent underground trains. This is possible in part due to the quiet, water-cooled three-phase AC traction motors.
