The Hamburg S-Bahn is the rapid mass transit railway network for the local public transportation sector in the major metropolitan area of Hamburg, Germany. Founded in 1907 to serve the citizens of the city on the Elbe, the S-Bahn now has six lines serving 68 stations on 147 kilometres of track. In 2012, it transported a total of 259 million guests.
Since 2010, the S-Bahn Hamburg exclusively uses CO2-free renewable electricity generated from German hydroelectric power stations. Further, it is the only rapid transit rail system in Germany which uses direct current (1200 Volt) as well as alternating current (15kV / 16.7 Hz), taken from conventional overhead catenaries.
Since November 2013, all traffic running over the Hamburg S-Bahn is monitored and controlled out of the new Operating and Service Centre (Betriebs- und Servicezentrale / BSZ) in the Hammerbrook district of Hamburg. Here around 80 employees are responsible for coordinating and troubleshooting every train, every driver, every switch point, and even every one of the 234 train indicators on the passenger platforms. All operational data concerning the trains and the stations, as well as the emergency and the IT systems converge here.
The train and district scheduling team supervises all the traffic and intervenes with corrective measures in case of disruptions. Here, every second counts. Decisions need to be made quickly to minimise negative impacts for passengers and return as quickly as possible to the regular scheduled timetables. Finally, in addition to the Hammerbrook facility, an emergency command station in Altona will be fully integrated with the WEYTEC solution in 2015.
Goal: System Integration
For the Hamburg S-Bahn, traffic control for all the rail turnouts and signals is regulated in 17 local signal boxes, whereby one operates mechanically, six electro-mechanically, eight per push button routing, and two electronically. Into this diverse and challenging environment, WEYTEC has delivered a unified solution based upon the WEYTEC distributionPLATFORM technology, but also including multiple point-to-point connections. One of the most important criteria for this project, therefore, was the ability to integrate the connection, transmission and management of analogue and digital video signals from a very broad variety of systems, and this without the installation of new software on certified PCs.
