Introduction

Marking of a noStopping section on a viaduct of Semmeringbahn (Wiki banner.png)

Track sections can have some special conditions (signalised or not) i.e. limited availability of ( GSM-R ) train radio. They can be modelled using <restrictionArea>. In Germany these are given in “Compilation of temporary speed restrictions and other special features” [1]. It has additional information to driver timetable[2][3] and book of lines[4] given in the locomotive for train driver.

Fox example, the reasons for non stopping area are that stopping a burning train in a tunnel can have devastating consequences, but also that a train that comes to a stop at a difficult-to-access point complicates rescue efforts. In Germany, these markings are intended for tunnels over 500 m long that are traveled at speeds exceeding 160 km/h. In these sections the driver must go to the first hectometer mark without these markings and initiate braking there [5].

Track condition is also a function in the European Train Control System (ETCS) that informs a locomotive or the driver about the condition of the infrastructure ahead of the train [6].

Attributes:
  • type: type of restriction that applies in the restriction area (for most values see UNISIG Subset 026, chapter 7.5.1.77 M_TRACKCOND) (optional; xs:string; patterns: other:w{2,}; consider Use of tOtherEnumerationValue too.)
Possible values:
  • airTightness: In this section, a passenger train must be equipped exclusively with pressure-tight vehicles (usual on high-speed lines with long tunnels).
  • bigMetalMasses: metal masses outside of the tolerancesspecified l in 6.2.1.7 ETCS SUBSET-036
  • changeAllowedCurrentConsumption: change in the maximum allowable power consumption taken from the electrified track system.
  • changeTractionSystem: the change of electrified track system.
  • lowerPantograph: the pantograph has to be lowered
  • mainPowerSwitchOff: the main power engine has to be switched off
  • noEddyCurrentBrakeForEmergencyBrake: The use of eddy current brakes (external link) is not allowed on this track section for emergencz brake
  • noEddyCurrentBrakeForServiceBrake: The use of eddy current brakes (external link) is not allowed on this track section for service brake
  • noMagneticShoeBrake: it is forbidden to use the magnetic shoe brake
  • noRegenerativeBrake: it is forbidden to use regenerative braking
  • noSanding: it is forbidden to use sanding for increasing coefficient of adhesion (noSanding is not included in SUBSET-026 3.12.1.3)
  • noStopping: it is forbidden to stop
  • radioHole: In this section the reception of train radio is not ensured or not possible.
  • soundHorn
  • tunnelStoppingArea: In the middle of the tunnel is an emergency stopping area.,

  • id: the identifier of the object; this can be either of type xs:ID or UUID (obligatory; xs:ID); compare: Dev:Identities
*Notice:
Elements may have different parent elements. As a consequence they may be used in different contexts.
Please, consider this as well as a user of this Wiki as when developing this documentation further.
Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.
