Rhomberg Bahntechnik secures two contracts at Cologne Central Station.

In September 2019, Rhomberg Bahntechnik Essen was awarded the contract for the  ‘ETW-Köln HBF’ project by DB Netz AG. In addition, DB Energie GmbH awarded the railway technology specialists from essen with the contract for the associated neighbouring ‘ETW-Köln HBF-Maybachstr.’ project for a 10 KV TST.

 

The total order volume for these two projects amounts to around €2.7 million. Work began in January 2020 with the planning of the 10KV transformer station and will end in June 2025 with the completion of the contractual work, which includes the new construction and modernisation of the switch heating systems around Cologne Central Station. 

 

The projects comprise the extension and in part the renewal of the technical equipment, such as the construction of the transformer station contained in the basement of the operating building, the medium-voltage system extension including telecontrol technology, the earthing system, the cable pull as well as the associated planning services and the resulting low-voltage systems of the ‘ESTW-Köln Hbf’ control centre and its technical and maintenance rooms. 

 

The greatest challenge in this project is that during the entire deconstruction and new construction work, the dispatchers’ technology in the operating building must remain in operation and under no circumstances be influenced or even disturbed by the construction work in the same building. This was ensured by previous, costly switching of the energy supply. 

 

In addition, in the course of the renovation work in and on the building, electromobility on the Maybachstraße premises will also be taken into account: by 2025, a total of seven 22kW charging points with two charging sockets each for at least 14 electric vehicles will be installed in the car parks. The associated switchgear including the overvoltage protection devices are also to be supplied and installed by Rhomberg Bahntechnik.
