The results of such a meeting could be reported in an agreed document (for example a minutes of meeting) to which the actor exporting the safety related information can refer for closing the associated hazards in his hazard record.

Wrong Data Entry onboard (driver) The procedure for the specific configuration of the onboard subsystem depends on: ● the safety margins taken for the train braking system; ● the reaction delay of the train braking system (this one is directly dependent on the train length, especially for fret trains) Failure to update the train wheel diameter in the specific configuration of the onboard subsystem (maintenance staff).

Refer comment for line 1 here above. ● ● ● The maintenance of the onboard control command sub-system is done in compliance with the "Maintenance Procedure MP Z". The train wheel diameter is updated at defined intervals according to the procedure P W. For the Data Entry Process, the train drivers are trained and evaluated against the "Procedure P DE".
