railML schema changes since version 2
Between railML 2.0 and railML 2.1
Unfortunately no information available.
Between railML 2.1 and railML 2.2
Timetable subschema
To be filled.
Infrastructure subschema
ocp/@abbrevation
Fact: | The abbrevation attribute in the <ocp> element is declared deprecated. |
Reason: | There are multiple different abbreviations for single operation or control points. They can't be defined with one attribute. |
Recommendation: | Use the new <tsi> and/or <designator> elements instead. |
Related Trac Tickets: | #112 |
Related SVN Commits: | [335], [439] |
Old sample (railML 2.1): |
<ocp ... name="Passau Hbf." abbrevation="NPA"/> |
New sample (railML 2.2): |
<ocp ... name='Passau Hbf.' ...> <tsi country="80"/> <designator register='RL100' entry='NPA'/> <designator register='ENEE' entry='80-26506-6'/> <designator register='IBNR' entry='8000298'/> <designator register='DB640' entry='Pa'/> </ocp> |

Infrastructure subschema
trainRadio, trainRadioChange
Fact: | The <trainRadio> element and <trainRadioChange> element have been introduced. |
Recommendation: | Use the new <trainRadio> and <trainRadioChange> elements for defining conditions describing the train radio conditions along the track. |
Related Trac Tickets: | #43 |
Related SVN Commits: | [630] |
ocs element sample: |
<ocsElements> <trainRadioChanges> <trainRadioChange id="trc01" pos="57.46" dir="up" radioSystem="GSM-R" broadcastCalls="true"> </trainRadioChange> </trainRadioChanges> </ocsElements> |
infra attributes sample: |
<infraAttrGroups> <infraAttributes id="ia01"> <trainRadio radioSystem="GSM-R" broadcastCalls="true" /> </infraAttributes> </infraAttrGroups> |
speedChange/@vMax
Fact: | The parameter vMax in the <speedChange> element has been modified so that it can also handle the value "end". |
Recommendation: | Use the new value "end" in order to mark the end of a temporary speed restriction. |
Related Trac Tickets: | #97 |
Related SVN Commits: | [609] |
sample: |
<speedChange id="sc7" pos="256.7" vMax="end" dir="up" /> |
radiusChange/@geometryElementDescription
Fact: | A new attribute named geometryElementDescription has been added to the <radiusChange> element. It is an enumeration parameter, which provides the following entries that enable a more detailed description of transition curves:
|
Reason: | So far, it was not possible to model transition curves in railML although they represent a basic track alignment feature. |
Recommendation: | Use the new geometryElementDescription attribute in the <radiusChange> element for modelling the begin and end points of transition curves. |
Related Trac Tickets: | #251 |

sample for transition curve begin: |
<radiusChange ... geometryElementDescription='TS_clothoide' /> |
sample for transition curve end: |
<radiusChange ... geometryElementDescription='SC' /> |
