Modernisation through Innovation
Project Wiener Linien
The “Wiener Linien (Vienna Lines)
GmbH & Co. KG,” a subsidiary of
the “Wiener Stadtwerke Holding
AG,” is one of Europe’s most attractive
and reliable regional transport
companies, enjoying high customer
satisfaction. A modern fleet and
high safety standards have made
the Vienna Lines, with its 5 underground
railway lines and its extensive
network of tramways and city
buses, into one of the most innovative
regional transport companies
in Europe.
Within the scope of extensive modernisation
measures, Vienna Lines
is striving to expand its underground
railway network, as well
as to convert its entire communications
structure in several phases.
These measures include the construction
of new control centres and
expansion of existing centres, the
modernisation of audio/visual passenger
information systems, and
the step-by-step conversion of its
entire communications network to
IP technology.

Many Years of Experience
During previous projects, the NEUMANN COMMUNICATIONS SYS-
TEMS GES.m.b.H., a subsidiary of the ms NEUMANN ELEKTRONIK
GmbH, has already successfully completed projects for the Vienna
Lines. For example, in the last few years the following components
and systems have been integrated into the communications struc-
ture of the Vienna underground railway network:
For example, in the last few
years the following compo-
nents and systems have been
integrated into the communi-
cations structure of the Vienna
underground railway network:
The Project
The overall project is organised
into the following sub-projects:
• 47 MDK Centres (Multifunctional Digital Communications
Systems), another 17 are in planning
• 31 MZV Centres (Microprocessor-controlled Central
Exchange systems)
The now 30 years of development continuity of the Vienna Lines,
where a diversity of the various generations of equipment and sys-
tems have been employed, give rise to the need for a new control
centre as well as the necessity to systematically change over to new
technologies. Based on our many years of experience as a system
manufacturer and system integrator for information and safety
technology, our company has the necessary know-how and experti-
se to successfully implement this challenging large-scale project.
• over 250 intercom stations (MTSA, MTSD, WFA and WFD) on
platforms and in control centres
• over 500 hands-free emergency call units (NES92 and
Emergency Call-C technology) on platforms and in elevators
• over 900 loudspeaker circuits on platforms, at ticket
machines, ticket cancelling machines and escalators, in lane
dividers and in passages between building floors
• Conversion of older MZV-technology centres including
peripheral devices to digital technology; integration of new
MDK Centres that use IP technology
• Equipping the new “Erdberg” control centre (to take over
control of the entire Vienna underground in the future);
of the old “Karlsplatz” control centre as a conversion.
• Integration of existing peripherals (call stations and
hands-free emergency call equipment), train destination
displays, video surveillance and building control systems
(escalators and lighting control, fire alarm systems)

Increased Safety & More
Information
The goal of the conversion of the “Karlsplatz” control centre and
equipping the new “Erdberg” control centre is to allow them to be
remotely controlled and monitored from the new “Erdberg” centre
via an IP network by adding new components, as well as by integra-
ting existing systems now in operation at the old “Karlsplatz” site.
In the new “Erdberg” control centre, all exchange systems of the
existing communications centres will be integrated via gateways
into the IP network (VoIP). A ComServer will be used as the ex-
change for the gateways. In addition, a multiple operator system
will be set up with 16 operator stations (PC workstations) using IP
technology.
All PC workstations are be managed by a management system soft-
ware (master, slave). This management system provides integrated,
homogenous user interface. It allows simple, clear operation of all
of the functions needed to control the audio communications tech-
nology.
Thus allowing the following
operational procedures to be
optimised:
• Wide area coverage with passenger information
- partially/fully automated loudspeaker announcements
(digital announcement units)
- live announcements and group/collective calls
- audio-visual train destination displays
• Efficient processing of intercom/PA connections and
uniform operation for emergency calls
• Increased feeling of safety for passengers and company
employees
- video surveillance systems
- hands-free emergency call equipment
• Easier operation of the control systems in the control
centres
- Management systems
- Remote control and remote monitoring of the
control centres
