UIC IRS 90940 - edition 2: SFERA protocol


UIC Sectors and Stakeholders approval


Welcome and thank you for taking the time to consider this document.

What is SFERA?

SFERA is intended to facilitate the use of Connected Driver Advisory Systems (C-DAS) for interoperable traffic by standardising the data exchange between on-board systems and Traffic Management Systems (TMS). The scope includes both ERTMS/ETCS Limited Supervision and Class B train protection systems. The format is also useful for Standalone DAS (S-DAS) by standardising data interfaces between Infrastructure Managers and Railway Undertakings.

Moving to edition 2 of the IRS 90940

After the publication of edition 1, the SFERA working group worked on improving the protocol and solved issues that could prevent an efficient implementation, also thanks to the feedback from the SFERA user group.

This approval is the first step towards external to the working group parties for the publication of the IRS 90940 in its edition 2.
