Electrical Systems Compatibility for Advanced Railway Vehicles


Objectives and content
Promotion of environment friendly, reliable and safe rail
transport of passengers and goods within and across
national borders is a major EU objective In order to
reach this goal, interoperability between all subsystems
of a rail network is a prerequisite. Numerous technical
barriers, such as different track widths, supply
voltages, or signalling systems have long been
identified. A fourth barrier, the electrical
compatibility of new vehicles with the existing power
supply, signalling and vehicles, has more recently been
found to be a major obstacle: large regional
transportation networks collapsed, electric vehicle
interaction caused protective shutdowns and delays,
signalling systems and barrier crossings malfunctioned,
information and telecommunication systems have been
disturbed, and TV/computer screens always flicker, all
due to a lack of electrical compatibility and
interoperability of components in an electrical rail
network. These effects have led to costly reworks and
delays for the manufacturing industry and to deteriorated
quality of service and capable utilisation for the
railway operators.
The objective of this project is to overcome these
problems by jointly tackling its most important aspects
in a multi-national and cross-company project team,
comprising several participating companies from the
system and component supplier side, the railway
operators, and from academic and industrial research. An
important goal of the project is to establish an open
modelling framework and adequate subsystem models for the
complete transportation system, enabling us, as a second
goal, to reliably predict and avoid interoperability
problems before putting a system into operation. This
will, as a third goal, had us to a design process and a
set of design recommendations for new vehicles as well as
input to new or updated European norms.
Three main technical risks of the project deserve special
numerous physical phenomena of different nature are
involved: the system modelling integration could be very
the overall model complexity may be to high to be
handled and a model reduction may not be possible without
losing important effects
potentially dangerous situations could be identified by
modelling, but not considered in standards and not
verifiable with measurements.
It results that particular attention must be paid to the
system integration issue. Modelling will be performed
with great care at the physical level rather than
demanding it to software packages, significant
simplifications will be done within known approximation,
both in the component models and after integration in the
system. Uncertainties in modelling results will be
eliminated by applying different independent modelling
techniques (e g determination, probabilistic) adequately
supported by specifically conceived measurements.
After the aforementioned risks are overcome, we expect:
at least 30% reduction in cost for demonstration of
compliance as a benefits for both suppliers and operators
decrease of network outage from an expected 1 h/year to
0.5h/yr. resulting in to passenger benefit of 25 ECU per
passenger for saved time/reliability of transportation to
further increase in rail transport safety (one disaster
less over five years)
competitive advantage on overseas competitors.
The project is planned for 42 months, with a total cost
of 5,64 MECU and a requested EU funding of 48%.
The project covers the Brite Euram areas of vehicle
design and system integration / 3b1" as well as
"Technologies for Vehicle Operation / 3b6i.
