Real-time passenger information about the destinations and arrival times makes travelling by train much more convenient. S-Bahn Hamburg, the local railway company for Hamburg, is aware of this well-known fact and wants their customers to enjoy the benefits of real-time information too. In order to digitalize the train stations, S-Bahn Hamburg replaces former analogue display boards and train destination displays with digital information boards. Passengers have now permanent access to the latest information.
The visual differentiation of the S-Bahn lines is even better thanks to coloured markings. Thanks to digital displays special information such as timetable changes and train length displays are even easier to recognise.
In order to ensure that this new generation of train destination displays can be supplied with real-time data from the control centre, reliable network technology is required. Any deviations from the timetable must reach the passengers on time – without any interruption.
The SHDSL-modems from Pan Dacom Direkt offer a wide range of applications thanks to their large product family. They all share a small form factor of the metal chassis and fail-safe hardware. This means that the passengers of S-Bahn Hamburg always receive the real-time information about their connection and journey.
The SHDSL-technology can bridge long distances and connect the entire environment, while it is aggregated it in a central subrack.
In total, 20 train destination displays were aggregated in such a subrack from Pan Dacom Direkt and forwarded via an integrated switch. A bandwidth of 15 Mbps per wire pair is more than sufficient to be used in other scenarios in the future. Due to the longstanding business relationship with Deutsche Bahn AG, the Pan Dacom Direkt was the first choice for S-Bahn Hamburg for this project: „At S-Bahn Hamburg, we chose modems from Pan Dacom Direkt because of their high flexibility in configuration, stability and performance in operation, as well as a wide range of options in automated monitoring. We are absolutely satisfied with the use so far and can therefore definitely recommend the products,“ said Dominik Tamm, IT Project Manager of S-Bahn Hamburg.
The Hamburg S-Bahn GmbH is a suburban commuter railway network in the Hamburg Metropolitan Region (Germany). It operates six lines on an extensive rail network of 147 kilometres. The S-Bahn Hamburg transports up to 750,000 passengers on 1,200 journeys daily.
