---|---|---|---|---|---|
<TT:operationalTrainSectionPart> | TT:001 | 2022-09-15 | 2022-10-13 | There is always only a single successor and predecessor for an <operationalTrainSectionPart> in the chain of <operationalTrainSectionPart>s that are linked via the attribute @next. | |
<TT:operationalTrainVariant> | TT:002 | 2023-01-12 | 2023-04-06 | When calculating which <operationalTrainVariant> of an <operationalTrain> is valid on a particular day always a maximum of one active <operationalTrainVariant> shall be the result. If the result is more than one <operationalTrainVariant>, all except one shall be marked as <isCancelled> or <isOnRequest>. | |
<TT:commercialTrainVariant> | TT:003 | 2023-01-12 | 2023-04-06 | When calculating which <commercialTrainVariant> of an <commercialTrain> is valid on a particular day always a maximum of one active <commercialTrainVariant> shall be the result. If the result is more than one <commercialTrainVariant>, all except one shall be marked as <isCancelled> or <isOnRequest>. | |
<TT:operationalTrainSection> | TT:004 | 2022-01-12 | 2023-03-09 | The itinerary sections of an <operationalTrainVariant>, defined by the <operationalTrainSection>s and their respective <range>s, that are not <isCancelled> and not marked as <isOnRequest>, must be pairwise disjoint, except for their respective first and last <baseItineraryPoint>s. | |
<TT:operationalTrainSection> | TT:005 | 2022-01-12 | 2023-03-09 | The first(last) <baseItineraryPoint> of each <operationalTrainSection> within an <operationalTrainVariant> must either be the referenced <itinerary>'s first(last) <baseItineraryPoint>, or coincide with another section's last(first) <baseItineraryPoint>. | |
<TT:commercialTrainSection> | TT:006 | 2022-01-12 | 2023-03-09 | The itinerary sections of an <commercialTrainVariant>, defined by the <commercialTrainSection>s and their respective <range>s, that are not <isCancelled> and not marked as <isOnRequest>, must be pairwise disjoint, except for their respective first and last <baseItineraryPoint>s. | |
<TT:commercialTrainSection> | TT:007 | 2022-01-12 | 2023-03-09 | The first(last) <baseItineraryPoint> of each <commercialTrainSection> within an <commercialTrainVariant> must either be the referenced <itinerary>'s first(last) <baseItineraryPoint>, or coincide with another section's last(first) <baseItineraryPoint>. | |
<RTM:isValid>, <CO:validityTime:period> | IS:001 | 2024-01-15 |
Starting time stamp (e.g. "from") shall be lower or equal any ending time stamp (e.g. "to") if both are given. Must not overlap with other validity periods. | ||
<IS:trainProtectionElement> | IS:002 | 2021-02-26 |
<trainProtectionElement> shall only be used for national and/or legacy train protection systems. ETCS-based systems must not be modeled using <trainProtectionElement>. | ||
<IS:levelCrossingIS> | IS:003 | 2023-10-23 |
<levelCrossingIS> should not have a <crossesElement> child of type railway. This case should be represented either by a <crossing> in case of a simple crossing, or by a <switchIS> of type doubleSwitchCrossing or singleSwitchCrossing. | ||
<IS:underCrossing>, <IS:overCrossing> | IS:004 | 2023-10-23 | was declined | 2024-02-26 | should only have a <crossesElement> child of type railway when railway crosses railway (not on the same level!). |
<IS:signalConstruction> | IS:005 | 2024-01-22 |
@height and @positionAtTrack should not be used with @type=virtual. | ||
<IS:line> | IS:006 | 2024-01-29 |
each line with own mileage should always be associated with its own <linearPositioningSystem>, i.e. Advanced example of railML has three lines with their own mileages, thus should have thee <linearPositioningSystem>s. | ||
<IS:border> | IS:007 | 2024-01-29 |
if @isOpenEnd="true" then statement @type="area" is true. | ||
<IS:netElement> | IS:008 | 2024-02-02 |
Aggregation of net elements should follow the tree data structure. See figure below. This means that no two (mesoscopic) net elements can aggregate same (microscopic) net element. In other words, (microscopic) net element can be aggregated by at most one (mesoscopic) net element. | ||
<IS:netElement> | IS:009 | 2024-02-02 |
Linear (geometric) coordinates (explicit or implicit, e.g. calculated as a sum of the coordinate of beginning and the length of the net element) of the same place represented at different levels of aggregation should have the same value. In the figure below (linear) coordinate the coordinate of e.g. end of ne1 should be same as one of ne1.2. | ||
