As a driving force behind the advancement of the open-source railway markup language, we are dedicated to promoting the principles of  open-source software , characterized by peer production, source code availability, and accessible documentation, all offered to the public at no cost. Our obligation to these goals has stayed steady since our origin in 2002.

Our primary goal is to facilitate seamless communication among diverse railway applications. In today's world, connecting various railway software packages often presents significant challenges. To address this issue, the initiative was established, committed to exploring, debating, and presenting systematic, XML-based solutions for simplifying data exchange between railway applications.

The railML standard is not the product of a centralised body. Instead it has been developed in a work and discussion process among the involved partners. All interested institutions and businesses are invited to contact us and participate in the initiative.

This website provides additional information on our project. The results of are available for download on this website after agreeing to our licensing conditions. You will find XML schemas, sample data files and the detailed railML specifications.

Due to the complexity of railway data and the many syntactic differences among the railways, software using the railML format has to be certified. The certification ensures the quality of the railML interfaces and brings no additional costs, except the one-time certification fee.
