Suburban Railway Line S21 – uVPA Berlin Central Station

Planning of Electrotechnical System 50Hz

The new-construction of the suburban railway line S21 is an important element for a sustainable light-rail system in Berlin. Accordingly, the commissioning of the new railway line allows the reorganisation of the entire transport network of Berlin’s light-rail system. The new route runs from the Nordring via Berlin Central Station and Potsdamer Platz to Yorckstrasse. This will connect the northern and southern suburban railway lines as well as the circle line to the Central Station and create a new suburban rail junction. Passengers have convenient transfer options between important suburban railway lines, almost all regional and long-distance train lines as well as various metro and bus routes.

ZPP was commissioned by DB InfraGO AG to plan the 50Hz electrotechnical system for the final state of the underground passenger traffic system (uVPA) of S21 at Berlin Central Station according to service phase 3 (conceptual design) of HOAI §55 “Technical Equipment” as well as the technical code Ril208.

In addition to the design of the passage areas made of wall coverings with illuminated glass, a roofing with glass structure (glass cube, lighting) and handrail lighting, the general and safety supplies for an immense number of power consumers were also important.

Thus, over 700 lights, train information systems, advertising showcases, ticket machines, fire doors, clocks, escalators, elevators and much more not only had to find their place, but also the right power supply connection. This requires targeted and communication-intensive coordination of all planning trades. Even small changes in planning, e.g. to the ventilation system or the selection of lights, have an impact on the planning of the electrotechnical systems.
