This European Standard defines the requirements for the provision, visibility, readability, maintenance and testing of a specific set of ERTMS trackside boards associated with the following DMI and ETCS track conditions: - ETCS stop marker; - ETCS location marker, the trackside ETCS signal to identify a specific location on the line; - level transition, corresponding to transitions between ETCS levels; - lower pantograph; - pantograph lowered; - raise pantograph; - neutral section announcement; - neutral section; - end of neutral section; - GSM-R network border marker. This European Standard includes the arrangement of the boards and their interface with existing systems (track, cab design including cab sight lines, visibility by the driver and train head lamps). NOTE 1 The ETCS and GSM-R signs are needed when the information normally associated with the DMI symbols is provided at the trackside. NOTE 2 The application of ERTMS trackside boards is not within the scope of this standard. Sighting requirements are not included within the scope of this standard. Sighting requirements for the boards may be different according to their level of authority: marker boards ‘End of Authority’ need to be treated with the same level of authority as a signal and may have enhanced sighting requirements; the remaining boards may be sighted as generic signage sighting rules. The sighting process needs to be implemented in accordance with national safety rules.
