UIC has produced two new Interim GSM-R specifications: “EIRENE Functional Requirements Specification version 7.1” and “EIRENE System Requirements Specification version 15.1". These contain new features which improve and facilitate the use of GSM-R such as “Shunting”, “EIRENE Data Only Radio” and “Alerting a controller”. The new features are strictly optional, which means that they do not affect the EU Control Command and Signalling Technical specifications mandatory for interoperability requirements.

The EIRENE Functional Requirements Specification version 7 and the EIRENE System Requirements Specification version 15, part of TSI CCS - Annex A are still considered by the European Technical Specification for Interoperability (TSI) to be the official GSM-R specifications.

Both documents were agreed upon by the European Railway Agency (ERA), the Community of European Railways (CER), the European Infrastructure Managers (EIM), the Association of European Rail Industry (UNIFE) and the GSM-R Industry Group (GSM-R IG) on 8 July 2010.

The interim specifications are presented in both a “clean” version and a version in which changes have been highlighted in yellow to indicate the points where the interim EIRENE versions differ from the “in force” (from the point of view of TSI) EIRENE versions.
