Interfaces Between CCS trackside and
other subsystems
Joint sector research and validation for the
specification of the electromagnetic
compatibility
Sector involvement
• Cross acceptance Working party
– Collection and classification of national rules
• CCS TSI editing including update of the
“Interfaces Between CCS trackside and other
subsystems”
– Specification of target system
• EMC Working Party
– Contributing to the EMC target specification
– Projects aiming in closing the EMC open points

Motivation of the sector involvement
• Requirements for the compatibility between vehicles
and axle counters + track circuits for the
authorisation of vehicles are currently an open point
in the TSI CCS.
– As a consequence national rules have to be followed
today, in some cases national rules do not exist
• The joint sector projects aim to
– a reach broad European acceptance of the new limits
– test specifications
– provide the scientific input for the closure of open points
related to the vehicle/train detection interface

Overview of EMC Project planning
• 2010: partial validation of TS 50238-2 (vehicles
and track circuits in the 15kV network)
• 2011-?: validation of TS 50238-3 (vehicles and
axle counters)
• 2012-2014: closure of TSI CCS open points in FP7
4th call project proposal EUREMCO
• 2013-2015: closure of TSI CCS open point “eddy
current brake” – CTG project idea for FP7 5th call

EMC phase 1
• TS 50238-2 establishes new vehicles emission limits
and vehicle test methods for the compatibility with
track circuits
• funding provided by CER/EIM/UIC for the partial
validation in the 15kV network
• Tests have been carried out by DB, SBB and ÖBB with
the support of Siemens
• Test report expected by end of December 2010
• To be included in the CCS TSI at the next revision

EMC phase 2
• TS 50238-3 establishes new vehicles emission limits and
vehicle test methods for the compatibility with axle counters
• UIC applied for TEN-T co-funding for a joint validation
campaign of 8 CER/EIM (UIC) members in all networks in 2011
• Expected outcome:
– Validated list of practically relevant parameters
– Susceptibility limits for axle counters missing so far
– Validation of vehicle emission limits and vehicle test method of TS
50238-3 and proposal for improvements
– Proposal for the quantification of other relevant parameters
• Funding rejected – further strategy to be developed !!!

EMC phase 3 - EUREMCO
• If positively approved, EUREMCO will finalise the validation of
the TS 50238-2 (track circuits) for DC 1,5kV, 3kV and AC
15kV/16,7Hz, 25kV/50Hz
• Expected outcomes:
– Set of test signals to test track circuits again transients
– Clear definitions and specifications for the assessment of transients
– Limits for the characteristic parameters of transients for both vehicles
and power supply (sources) and track circuits (destination)
– Clear understanding of the influence of the infrastructure on the
conducted emissions of vehicles
– Transfer function from test results within the same power supply
system (for track circuits).
– Requirements that rolling stocks will not disrupt track circuits on nonelectrified lines

EUREMCO: EUropean Rail
ElectroMagnetic COmpatibility
• UNIFE applied jointly with 10 UNIFE/CER/EIM/UIC members
for FP7 4th call co-funding for a project in 2012-14
• Funding: €2,1m, Budget: €3,6m

Remaining open point:
Eddy current brake
• A CTG project idea which has been picked up by ERRAC in the
« sector wishlist » for the FP7 5th for a joint project of
UNIFE/CER/EIM/UIC members in 2013-15
• Funding: open
• Expected outcome:
– Improve understanding of the interaction of the eddy current
brake with the track and trackside signalling equipment
– Identify critical thermal, mechanic and electromagnetic
parameters and its related vehicle and trackside compatibility
limits
– Develop design, engineering and operational guidelines for new
eddy current brakes and new trackside signalling equipment

Conclusion
• Sector target – simplified vehicle autorisation
through:
– Harmonised EMC limits, both for signalling susceptibility as well as for
vehicle emissions
– Harmonised test method proving the vehicle conformity with the
specified limits
• Final goal – one assessement applicable for all
networks compliant with the INTERFACE document
• Precondition:
– Strong cooperation of all stakeholders: railway
undertakings, infrastructure managers as well as
manufacturers (both of vehicles as well as of signalling)
