Closed - circuit surveillance system

Surveillance data processing systems shall accommodate the timely sharing of relevant, accurate, consistent and coherent information between them to ensure optimised operations through different parts of the EATMN.

Separate status codes must be used to identify correctly functioning emission control systems and those emission control systems which need further vehicle operation to be fully evaluated.

The control and command and signalling systems should continue to provide for safe passage of trains permitted to run under degraded conditions.

The control and command and signalling equipment installed in the train drivers' cabs must permit normal operation, under the specified conditions, throughout the trans-European conventional rail system.

To avoid any delays in the application of that system during the period in which the mills operate, a deadline should be laid down for submitting applications for approval under the special control arrangements to the Commission and provision should be made for granting temporary approval.

The design of the vital equipment, of the running, traction and braking equipment and of the control and command system must be such as to enable the train to continue its mission, in a specific degraded situation, without adverse consequences for the equipment remaining in service.

Any irrational emission control strategy which results in a reduction in effectiveness of the emission control system under normal operating conditions at low temperature driving, so far as not covered by the standardized emission tests, may be considered a defeat device.

Surveillance data processing systems shall accommodate the timely sharing of relevant, accurate, consistent and coherent information between them to ensure optimised operations through different parts of the EATMN.

the safety-critical interfaces whose characteristics are liable to change in the course of system operation must be the focus of monitoring and maintenance plans that define the conditions for monitoring and correcting those elements.

general and detailed drawings in line with execution, electrical and hydraulic diagrams, control-circuit diagrams, description of dat-processing and automatic systems, operating and maintenance manuals, etc.;

The network shall offer users a high level of quality and safety, owing to its continuity and to gradual implementation of its interoperability, brought about in particular by technical harmonization and a harmonized command and control system.

In the case of subsystems concerning the environment, operation or users, TSIs will be drawn up only to the extent necessary to ensure interoperability of the trans-European high-speed rail system in the fields of infrastructure, energy, control and command, signalling and rolling stock.
