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


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 FMAll 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-management50 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
