railML (Data Exchange)

Overview This page describes the relation between RailTopoModel® as model and railML® as exchange format.

Very closely related to the evolution of the RailTopoModel^® is the work done by members of railML.org. railML^® is an open-source XML-based data exchange format for IT applications in railways. railML^® is developed and maintained by the railML.org initiative and it has been published so far up to version 2.3. Currently, railML.org is actively contributing to the UIC RailTopoModel^® Expert Group with the objective to base its new version, railML^® 3, on the fundament of the RailTopoModel^®. Thus, railML^® 3.0 can be considered to being the exchange format for any infrastructure data base following the RailTopoModel^® concept. The current state of development of railML^® 3 is described on the website besides infrastructure, railML^® is also able to handle information about timetable, rolling stock and interlocking. Thus, being a widely applicable data exchange format, railML^® is used by many railways, manufacturers and other institutions for internal and external data exchange. Further information on railML^® can be found at https://www.railml.org.

Considering the work done by the railML^® initiative project in co-operation with this modelling work, there are currently two products available to facilitate the exchange of data in the domain of railway infrastructure.

Logical model	The RailTopoModel® is a generic railway data model designed to support current and future business needs. It is particularly useful for: Engineering activities - mainly based on installations and components, and Circulation activities - mainly based on routing and scheduling.
railML®	railML® 3 is the latest evolution of the format created by railML.org. railML® 3 was specifically developed to be compliant to the UIC's RailTopoModel®.

Thus, railML^® can be viewed as the first benefit of RailTopoModel^®. Figure 2 summarises the role that RailTopoModel^® and railML^® would play when fully integrated in existing systems.

Investing in a standardised railway data exchange format will provide multiple benefits for the sector, including:

• Improved data quality,
• More efficient business performance,
• Streamlined and re-usable development,
• Integrated IT systems, and
• Return on investments.
