Division 4.3.1 Minimum performance requirements

In order to run on the interoperable network and under conditions allowing trains to slot smoothly into the overall traffic pattern, all high-speed rolling stock shall be required to guarantee minimum traction and braking performance levels. The trains shall have sufficient standby and backup capacity to ensure that these performance levels are maintained or only slightly downgraded in case of breakdown in systems or modules contributing to these processes (traction chain from pantograph to axles, mechanical/electrical braking equipment). These margins and redundancies are defined in detail in the characteristics contained in Sections 4.3.2 to 4.3.6, 4.3.9, 4.3.11, 4.3.15 and 4.3.16.

In the event of the failure of rolling stock equipment or functions, or passenger overload, the rolling stock operator shall, in full knowledge of the consequences, have defined the acceptable limits and operating conditions associated with each degraded mode. For this purpose, the various degraded modes that can be experienced in service shall be described and indexed in a special document.

Performance levels demanded on the other lines and feeder lines that do not form part of the interoperable network as such, but allow access to terminal installations (stations, train stabling tracks,), shall be defined in bi-or multilateral agreements between operators and infrastructure managers depending on the service levels planned.
