The railML subschemas

The railML® specification contains subschemas for four main areas: infrastructure, timetable, rolling stock and interlocking. These topics are themselves further divided into additional subschemas that address more specific areas. Additional railML-subschemas like for crew rostering, asset management or real-time data are being planned and discussed.

One railML file can contain several subschemas. The division into subschemas allows each individual railML-compatible application to apply the parts of the full schema - e.g. the subschemas - in various combinations.
