Infrastructure (IS)
IS root element — IS use cases — Concepts & examples
General Information
The railML® Infrastructure subschema is focused on the description of the railway network infrastructure including all its various facets that are needed by the data exchange applications. In particular, the railML® infrastructure schema contains the following information:
- Topology. The track network is described as a topological node edge model (see <topology>).
- Coordinates. All railway infrastructure elements can be located in an arbitrary 2- or 3-dimensional coordinate system, e.g. the WGS84 that is widely used by today's navigation software, see <spotLocation>.
- Geometry. The track geometry can be described in terms of <horizontalCurve> and <gradientCurve>.
- Railway infrastructure elements enclose a variety of railway relevant assets that can be found on, under, over or next to the railway track, e.g. <balises>, <platformEdges> and <levelCrossingsIS>. See <functionalInfrastructure>
- Further located elements encompass elements that are closely linked with the railway infrastructure, but that "cannot be touched", e.g. <speeds> and <restrictionAreas>.
The main element of this subschema is <infrastructure>.
Please visit the railML-Website (link to the railML® website) for more detailed information about the Infrastructure subschema or send an email to the coordinator of the subschema.
Documentation
For more information please refer to the folloging pages:
- <infrastructure> — documentation of the main element
- Infrastructure Elements — overview off all XML elements found in the infrastructure subschema
- UML visualization of the current railML® 3 IS subschema
- Examples (link to the railML® website) — collection of examples provided by the railML partners (railML.org login needed)
All elements in the Wiki are documented with the elment name and the prefix of their subschema (IS: for infrastructure) — e.g. the wiki documentation for <track> is found here https://wiki3.railml.org/wiki/IS:track.
