Semantics / Bedeutung
The element stopDescription describes data concerning the stop (or pass) at the parent ocpTT.
Das Element stopDescription beschreibt Daten, die den Halt (oder die Durchfahrt) im aktuellen ocpTT charakterisieren.(introduced with version 2.5)
Please, be aware of the semantic constraint(s)!
Attributes of stopDescription / Attribute von stopDescription
- commercial: This characterizes the reason for the stop. It can either be commercial or operational. In case of a passenger train, a commercial stop would be a stop, where passengers can enter or alight from the train. An operational stop might for example be used for changing the staff.
Dies beschreibt den Grund für den Halt. Er kann entweder kommerziell (Verkehrshalt) oder operativ (Betriebshalt oder Diensthalt) sein. Im Falle eines Personenzuges wäre ein kommerzieller Halt eine Halt, an der Fahrgäste ein- oder aussteigen können. Ein betrieblicher Halt könnte zum Beispiel für das Wechseln des Personals genutzt werden.
- stopOnRequest: This indicates a commercial stop, depending on a certain demand, such as passengers or goods waiting for the train to stop. A stop on request is a special kind of a commercial stop. This attribute is to be defined only if commercial="true".
Bedarfshalt: Ein Bedarfshalt ist eine besondere Form des Verkehrshalts. An einem mit stopOnRequest="true" markierten Stop wird nur gehalten, sofern ein entsprechender Bedarf festgestellt wird, also etwa ein- oder aussteigende Fahrgäste, bzw. zu ladende oder zu entladende Fracht. Das Attribut stopOnRequest ist nur anzugeben, wenn commercial="true" ist.
- onOff: This describes, if passengers/goods are not supposed to enter or leave the train if it is a commercial stop (commercial="true"). The attribute is used for passenger information and with the operational background to encode whether a train may possibly depart before the scheduled time. Concerning semantical constraints, see below.
z.B. "Halt nur zum Einsteigen"
Possible values are:
- both: Train stops to alight as well as to be entered. This is the normal case for most of the commercial stops and therefore the default value.
- on: Train stops to be entered only or to receive goods only but not to alight/unload.
- off: Train stops to alight from the train only or to unload goods but not to be entered/receive.
- purpose: This describes the reason for the stop in a detailed but not predefined way.
Please be aware that this attribute is only intended to forward simple remarks/explanations from one end-user to another end-user. It is not to be used to contain computer-processable data, nor shall it be parsed by programmes in any way. In case of semantical overlaps or discrepancies especially to <stopActivities> (introduced with version 2.4), any processable <stopActivity> has priority over possible humanly interpretable “purposes”. However, purpose is used to give further (but not computer-processable) information in case of the <stopActivity> type=”misc”.

- guaranteedPass: (introduced with version 2.2) The train shall pass through this operating point and must not come to a stop for operational reasons (occupied block section, train crossing, ...). Not to be confused with emergency brake override sections. This is used, for example, for heavy goods trains, as they would otherwise not be able to restart due to the high load at this operating point. This attribute is only to be used if <ocpTT>.ocpType is set to "pass".
Der Zug sollte an dieser Betriebsstelle zwingend durchfahren und nicht aus betrieblichen Gründen (belegter Blockabschnitt, Zugkreuzung, ...) zum Halten kommen. Nicht zu Verwechseln mit einem Notbremsüberbrückungs-Abschnitt (external link). Dies wird zum Beispiel bei schweren Güterzügen verwendet, da diese wegen der hohen Last an dieser Betriebsstelle sonst nicht wieder anfahren könnten (garantierte Durchfahrt). Dieses Attribut ist nur zu verwenden, wenn <ocpTT>.ocpTType auf "pass" gesetzt ist.
- operationalStopOrdered: (introduced with version 2.2) This indicates that the stop is requested by the train operator (Railway Undertaking), i. e. it is not a commercial stop concerning traffic (not for passengers, not for payload) but anyway the stop is ordered for operational reasons of the operator. This attribute is not to be defined if commercial is set to true.
bestellter Betriebshalt: Das Attribut ist nur anzugeben, wenn commercial="false" ist.
- operatingPeriodRef: This refers to the id attribute of the associated <operatingPeriod> element.
Used to reduce the operating days of the stop compared to the operating days of the train part. If not defined, the stop applies to all operating days of the parent train part.
- stopPostRef: This refers to the id attribute of the associated <stopPost> element.
(introduced with version 2.2)
- xs:anyAttribute: This provides an extension point for non-railML® attributes in a foreign namespace. How to use it?

Notes / Anmerkungen
If a stop does not apply to all operating days of the train - i. e. the train runs through at several days - the attribute operatingPeriodRef can be used to reduce the operating days of the stop against the operating days of the train. However, be aware that other given attributes as run times, supplements etc. become incorrect by this practice. Also, it can only be used to change between a certain stop and run through but not to switch between two different stop types depending on the days of operation. Therefore, many applications would probably split the train into two instead of using operatingPeriodRef.
