Pr16623 Basic parameters for train detection systems
to allow safe detection of RST
Resolution 34/1
Noting BT decision D136/033 to set back project 16623
to PWI stage, SC9XA resolves to initiate a survey group
within WGA4-2 with the remit of identifying the
characteristics of train detection that need to be defined,
with the objective of initiating a New Work Item
Proposal.

Report from the survey group/WGA4-2
• Progress to date
• 28 September – 1st meeting of WGA4-2
Decision taken to continue work in two subgroups
focused on track circuits and axle counters,
correspondingly
• 10 November – 1st meeting of TC survey group
• 11 November – 1st meeting of AxC survey group
• 2 parameters list developed accordingly and responsibility
for managing assigned
• Additional responsibility identified for IM for maintaining
parameters in the framework of interoperability
Convenor of WGA4-2
M Petkova
Way forward
•SC9XA issues the report of the survey group to
all National Committees for 2 month enquiry to
finalise the new mandate for WGA4-2.
•WGA4-2 starts work immediately, to avoid
further delay to the introduction of
Interoperability
•WGA4-2 remains a joint WG. New members
are welcome.

16.7 Hz traction – next step for
FM
All Track Circuits currently listed as preferred can be
taken into account for the FM.
- Austria – S50108914 106,7 Hz; S1722-8 100 Hz
- Germany – FTGS 46, FTGS 917
- Netherlands – FTGS 46, FTGS 917, HVI
- Norway – FTGS 46, FTGS 917, 95 Hz, 105 Hz
- Sweden – JRK10470
-Switzerland – UGSK 95, UGSK 3, FTGS 46, FTGS 917
-Note: TI21 listed as preferred in TS50238-2 but since
dropped from the list by the Norwegian National Rail
Administration

DC Traction
Proposed steps to achieve f-management
• 750 V DC special case
• 1 500 V DC and 3 000 V – f
management to be merged if possible,
as in the Energy TSI, across the f-range
• Audio F track circuits –1.6 – 7kHz

50Hz traction – proposed steps to
achieve f-management
50 Hz traction
• LF area
Single f + 75/275 Hz – special case
Coded track circuits
• Audio F track circuits –1.6 – 7kHz
• Higher F management – 50-70kHz
