Translation of "Dispositif de freinage à commande par gravité " (French → English) :

Structure, command and control system for all train equipment, electric current collection devices, traction and energy conversion units, on-board equipment for electricity consumption measuring, braking, coupling and running gear (bogies, axles, etc.) and suspension, doors, man/machine interfaces (driver, on-board staff and passengers, including the needs of persons with reduced mobility), passive or active safety devices and requisites for the health of passengers and on-board staff.

Structure, command and control system for all train equipment, current-collection devices, traction and energy conversion units, braking, coupling and running gear (bogies, axles, etc.) and suspension, doors, man/machine interfaces (driver, on-board staff and passengers, including the needs of persons with reduced mobility), passive or active safety devices and requisites for the health of passengers and on-board staff.

Structure, command and control system for all train equipment, the set of subsystems making up the different railway vehicle structures and including current-collection devices, traction and energy conversion units, braking, coupling and running gear (bogies, axles, etc.) and suspension, doors, interfaces between man (driver, on-board staff and passengers) and machine, passive or active safety devices and requisites for the health of passengers and on-board staff and for the proper care of persons with disabilities ...[+++] or reduced mobility.

When the requirements of this Appendix are fulfilled by means of a special device (e. g. controlled mechanically by the suspension of the vehicle), it shall be possible, in the event of the failure of this device or its means of control, to stop the vehicle under the conditions specified for secondary braking in the case of motor vehicles; for those vehicles authorised to tow a trailer fitted with air brakes, it shall be possible to achieve a pressure at the coupling head of the control line within the range specified in point 3.1.2 of this Appendix.

Where there are separate controls for the service and secondary braking devices, simultaneous actuation of the two controls must not render both the service and secondary braking devices inoperative, either when both braking devices are in good working order or when one of them is faulty.

In the case of a motor vehicle to which the coupling of a trailer equipped with a brake controlled by the driver of the drawing vehicle is authorised, the service braking device of the drawing vehicle must be fitted with a device so designed that if the trailer braking device should fail, or the air supply pipe (or such other type of connection as may be adopted) between the drawing vehicle and trailer should break, it will still be possible to brake the drawing vehicle with the effectiveness prescribed for the secondary braking ; it is accordingly prescribed, in particular, that this device be fitted to the drawing vehicle1.
