This document is applicable to the heavy rail system. This document 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 — 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 — no traction system fitted announcement — no traction system fitted indication — traction system AC 25 kV 50 Hz announcement — traction system AC 25 kV 50 Hz indication — traction system AC 15 kV 16,7 Hz announcement — traction system AC 15 kV 16,7 Hz indication — traction system DC 3 kV announcement — traction system DC 3 kV indication — traction system DC 1,5 kV announcement — traction system DC 1,5 kV indication — traction system DC 600/750 V announcement — traction system DC 600/750 V indication — activate the audible warning device (horn) indication — safe stopping area announcement — safe stopping area indication for start — safe stopping area indication for end — inhibition of brake announcement/indication for start/indication for revocation — level crossing marker NOTE 1 the brake MBs apply for any of the three brake types (eddy current, magnetic shoe, regenerative), whereas the exact type concerned would be known by the driver via existing Route knowledge. The following ETCS track conditions are outside the scope of this Standard: — Safe stopping area semi-continuous indication for in-between — Non-stopping area announcement — Non-stopping area announcement — Non stopping area indication for start — Non stopping area indication for end — Non stopping area semi-continuous indication for in-between — Close air conditioning intake announcement — Close air conditioning intake indication — Open air conditioning intake announcement — Open air conditioning intake indication This document 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). Mobile, backlit and temporary signs are not within the scope of this document. The application of ERTMS trackside boards is not within the scope of this document. Sighting requirements are not within the scope of this document. The sighting process needs to be implemented in accordance with national rules.
