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.
