Client

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.

BSZ

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 electroni-

cally. 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.

Solution

The customised solution for the Hamburg S-Bahn is built around the switching and integration capabilities of

the WEYTEC distributionPLATFORM. 84 different operational systems or sources are connected to 18 high-

tech operator workplaces, which can, in part, be selected on a daily basis at an operator’s discretion according

to the principle of “free seating”.

Each operator desk is equipped with up to eight monitors, one large 50'' LCD screen (shared between two

desks) and a MK06 Multifunctional Keyboard which is used to control and conveniently toggle between

sources and screens.

Almost all of the sources are centrally located in the system room, but available in real-time at any of the

output devices at the 18 operator stations.

According to Mr. Peter Voss, Head of Operational Engineering at the S-Bahn Hamburg, “One very important

point for us was to eliminate the enormous PC heat emissions from the working premises of the Operations

and Service Centre. This was elegantly accomplished by remoting the systems to a restricted access, air-con-

ditioned and secure server room. Apart from that, ambient noise from PC fans, etc. has also been dramatically

reduced. Furthermore, we simply did not have enough monitors per workplace to display all the required

sources. This has been perfectly solved with switching.”

Facility Management

Another requirement was to integrate the facility management system and enhance access control to the BSZ.

When a visitor rings the bell, a live video image of the entrance area is automatically switched to the display on

the MK06 Multifunctional Keyboard. Operators then communicate with the visitor via speakerphone and open

the door with a press of a button.

Benefits

For the S-Bahn Hamburg, the paramount benefit of the

WEYTEC Solution was the simplified provision of real-time

access to diverse IT applications at the operator stations.

Mr. Voss confirms, “The single biggest advantage with respect

to our requirements in the BSZ is the versatility of the swit-

ching capabilities between the different applications. On the

whole, we were convinced by WEYTEC’s highly flexible and

reliable solution concept, which on top of everything was quite

affordable from a cost perspective.”

Reference

Once again, Mr. Peter Voss comments on the realisation of the project and the collaboration with the WEY

Technology GmbH team: “To begin with, we would definitely choose WEYTEC to work with again, and we are

delighted to tell this to interested parties who visit us here and are facing similar problems. Next, I want to

mention the excellent support that we received. The project team was just great during the implementation

phase and it was remarkable to observe the unequivocal determination to achieve the project targets. This

was also apparent during the official overall project acceptance procedures conducted by the Federal Railways

Office (Eisenbahnbundesamt).” WEYTEC is now an official supplier to the German Railways (Deutsche Bahn).
