An example taken from our range of services

Since January 2004, we have been commissioned by DB Projektbau GmbH to carry out work on the 1733 section of track between Hanover and Würzburg. In the case of 10 tunnel structures with a total length of 27 kilometres, the retrofitting of the tunnel's emergency lighting system is taking place and some changes to the power supply system. The emergency lighting power supply units used and the tunnel monitoring centres have been developed by DB Bahnbau GmbH and comply with the latest regulations and are state-of-the-art technology.

The erection and installation work will take a total of 16 months and is scheduled for completion in May 2005.

Within Bahnbau Group, these services are performed by DB Bahnbau GmbH.
