Working model of the new ICE maintenance depot Dortmund

Construction of a new ICE maintenance depot Dortmund

A second additional ICE maintenace depot, located to the west of the Port of Dortmund, will be built on the 28-hectare site of a derelict yard by 2027. DB Fernverkehr’s new maintenance depot will be one hundred percent carbon neutral and supplied by renewable energy sources, using a solar thermal system for heating and hot water, for example.

At the heart of the project is the construction of an approximately 480-meter-long maintenance shed with four tracks including ancillary shops, warehouses and an administrative and staff building.

The planned outdoor facilities will comprise four covered interior cleaning platforms, which will also include any necessary supply and disposal facilities. An exterior cleaning facility is also planned. In addition, a logistics hall will supply on-board services. To facilitate light maintenance of ICE trains, the design provides for the installation of an underfloor wheel lathe (UWL), ultrasound/light section/measuring beam facility and camera portal.

In addition to the necessary rail infrastructure, the depot’s internal logistics will also comprise secondary material yards, delivery and drop-off zones, parking areas for industrial trucks as well as parking spaces and bicycle spaces for employees. The construction project also includes all modifications to DB Netz facilities, especially with regard to control-command and signaling and the overhead line network.
