Licence Terms

We highly appreciate that you would like to use railML® in your research project or your railway-specific software. However, please mind the different license conditions for the railML schemas, logos and labels:

railML schemas

All railML schemas are available for data exchange for the whole railway sector, irrespective of their usage. This can exemplarily be developments of interfaces, contribution to the further developement of the railML schemas or the usage of software with railML interfaces. The railML schemas may be used free of charge, after accepting the license conditions. Registered railML users are welcome to contribute to the further schema development.

As railML is a continous development, ongoing since 2002, the railML versions were published under slightly different licence conditions. Please select the applicable railML version to find more specific information.
