The ERTMS/ETCS System Requirements Specification, Subset-026, sets out several ERTMS/ETCS National Values that can be varied for particular configurations. These ERTMS/ETCS National Values cover many aspects of ERTMS/ETCS operation, including, for example, the maximum speeds permitted under different modes of operation. 1.2.1.2 A set of applies to a National Area. A National Area is a geographic region and does not necessarily align to political borders. GE/RT8072 sets out requirements for National Areas. 1.2.2 Scope 1.2.2.1 A set of is only relevant to ERTMS-fitted trains operating on ERTMS-fitted infrastructure. 1.2.2.2 The process set out in this document is applicable to ERTMS-fitted infrastructure irrespective of whether or not ERTMS-fitted trains operate on that infrastructure. 1.2.2.3 GE/RT8270 requires railway undertakings and infrastructure managers to maintain, update and make freely available to relevant parties the available data that describes asset characteristics relevant to compatibility. 1.2.2.4 The set of, determined in accordance with the process set out in this document describes asset characteristics that are relevant to compatibility between ERTMS-fitted infrastructure and ERTMS-fitted trains. 1.2.2.5 The set comprises the following: a) Q_NVDRIVER_ADHES Qualifier for the modification of trackside adhesion factor by driver. b) V_NVSHUNT Shunting mode (permitted) speed limit. c) V_NVSTFF Staff Responsible mode (permitted) speed limit. d) V_NVONSIGHT On Sight mode (permitted) speed limit. e) V_NVUNFIT Unfitted mode (permitted) speed limit. f) V_NVREL Release Speed (permitted) speed limit. g) D_NVROLL Roll away distance limit. h) Q_NVSRBKTRG Permission to use service brake when braking to a target is supervised. i) Q_NVEMRRLS Qualifier Emergency Brake Release.

Definitions D_NVOVTRP Maximum distance for overriding the train trip D_NVPOTRP specifies the maximum distance for which a train may reverse while the Onboard is in the PT mode. See Appendix A (of D_NVPOTRP Maximum distance for reversing in Post Trip mode D_NVPOTRP specifies the maximum distance for which a train may reverse while the Onboard is in the PT mode. See Appendix A (of D_NVROLL Roll away distance limit D_NVROLL specifies the maximum distance that a train can move in a direction that differs from that set by the driver s direction selector before an emergency brake application is made. See Appendix A (of D_NVSTFF Maximum distance for running in Staff Responsible mode D_NVSTFF specifies the maximum distance for travelling in SR mode. See Appendix A (of ERTMS European Rail Traffic Management System. ERTMS variables used to describe different technical properties or behaviours of the ERTMS entities (OBU, RBC, Balises, etc). The values assigned to these variables are usually not on a permanent basis; their renewal is done when a train crosses the border of a National Area. ETCS European Train Control System. M_NVCONTACT Onboard reaction when T_NVCONTACT expires M_NVCONTACT defines the action that is to be taken if the ETRMS/ETCS onboard equipment remains out of contact with the RBC equipment for a period defined by T_NVCONTACT. See Appendix A (of M_NVDERUN Entry of Driver ID permitted while running M_NVDERUN specifies whether a Driver ID can be entered into the DMI while the train is moving.

See Appendix A (of V_NVREL Release Speed (permitted) speed limit V_NVREL specifies the national value of the release speed. In general, it is used wherever the EOA and SvL do not coincide, and the EOA is marked on the trackside. See Appendix A (of V_NVSHUNT Shunting mode (permitted) speed limit V_NVSHUNT specifies a maximum speed to which the train is supervised when the ERTMS/ETCS onboard equipment is operating in the SH mode. See Appendix A (of V_NVSTFF Staff Responsible mode (permitted) speed limit V_NVSTFF specifies a maximum speed to which the train is supervised when the ERTMS/ETCS onboard equipment is operating in SR mode. See Appendix A (of V_NVSUPOVTRP Permitted speed limit to be supervised when the override EOA function is active V_NVSUPOVTRP specifies the ceiling speed to which the train is supervised while the override function is active.
