IS root element — IS use cases — Concepts & examples
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 <trackTopology>).
- 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 <geoCoord>.
- Geometry. The track geometry can be described in terms of <radiusChanges> and <gradientChanges>.
- 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 <levelCrossings>. See <trackElements>
- Further located elements encompass elements that are closely linked with the railway infrastructure, but that "cannot be touched", e.g. <speedProfiles> and <trackConditions>.
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.
