As railML.org promised during the 44th railML^® Conference conference in Rome, Italy in November 2023, we are happy to inform you about the publishing of the first Beta of the upcoming railML^® v3.3. The new railML 3.3 Beta can be downloaded from our website free of charge after login.

It includes updates for the timetable, infrastructure, interlocking and rolling stock subschemas. This version represents the next step towards a extended and more mature railML^® 3 version that enables you to describe and exchange data regarding all aspects of modern railway operations. We are continuously working on improving the modelling with support of our stakeholders and railML.org partners and are on track to publish the full railML 3.3 version during our next conference (Prague/Czechia) in November 2024.

The following changes have been incorporated into the railML's 3.3 beta version:

• LTCP: clean-up of modelling
• LTCP: removed notScheduledYet
• LTCP: changed modelling to ensure syntactically complete description
• LTCP: documentation of elements
• POMA: documentation of elements
• POMA: extendibility of enumerations
• POMA: clearer way of specifying where temporary restriction areas are located
• RTCI: documentation of elements
• TT: made sure passthroughs don't provide arrival and departure, instead they provide a passing time
• TT: introduction of operational connection for modelling of crossings and overtakings of trains as well as rollingstock or crew transfers from one train to the next.
• CO: segment table extended to 3^rd dimension
• ALL: removal of deprecated elements from railML 3.2

We invite you to download the Beta version and give us your feedback until October 1^st through the railML forum, by email or in the working group meetings.
