# Commission Decision of 30 May 2002 concerning the technical specification for interoperability relating to the control-command and signalling subsystem of the trans-European high-speed rail system referred to in Article 6(1) of Council Directive 96/48/EC (notified under document number C(2002) 1947) (Text with EEA relevance) (2002/731/EC), Division 4.2.1.2: Rolling stock interfaces

Extent: E+W+S+N.I.

A.. The train braking performance:
(i) the rolling stock TSI defines the braking performance of interoperable trains;
(ii) the class A control-command system shall provide the adaptability necessary to the real braking performance of the rolling stock;
(iii) upon a call for the emergency brake, the rolling stock subsystem shall prevent traction being applied. This requirement is promulgated in the rolling stock TSI.
B.. Compatibility with track-based train detection:
(i) the rolling stock shall have the characteristics necessary for the operation of train detection systems. Annex A, index 16 shall be used;
(ii) rail-mounted train detection systems shall have the characteristics necessary to be activated by rolling stock which conforms to the rolling stock TSI.
C.. Vehicle geometry and movement:
(i) the on-board antennae shall be positioned such that the vehicle kinematic gauge is respected as defined by the rolling stock TSI;
(ii) the position of the antennae on the rolling stock shall be such that reliable data communication is assured at the extremes of the track geometry capable of being traversed by the rolling stock. The movement and behaviour of the rolling stock shall be taken into account.
D.. Installation matters:
(i) environmental conditions. the resistance to the on-board physical environment is defined in Annex A, index 3;
(ii) electromagnetic compatibility with the on-board electrical environment. To ensure that the on-board equipment for the control-command systems may be universally used for new rolling stock accepted for operation upon the trans-European high-speed network, there shall be applied to the electrical environment of the rolling stock and the susceptibility of the interoperable control-command system to electrical interference a common specification of electromagnetic compatibility as defined in Annex A, index 4a. Integration tests will be required;
(iii) isolation of ETCS on-board equipment.
E.. Data interfaces:
the following sets of data interfaces with the train are required by class A equipment:
brakes,
train integrity (ETCS level 3),
train length.
These interfaces shall be adaptable for rolling stock operating in multiple units.
The interface requirements between the radio communications and the rolling stock subsystem are specified in Annex A, index 11. The other interface requirements between the control-command functions and the rolling stock subsystem are specified in Annex A, index 17.
F.. Electromagnetic compatibility between rolling stock and control-command trackside equipment: to ensure that new rolling stock accepted for use on all or part of the trans-European high-speed network will be compatible with the associated control-command infrastructure, there shall be a common specification describing the limits to conducted and induced traction current as well as electromagnetic field characteristics to be permitted; refer to Annex A, index 4b.
