On Tuesday 25th April 2000, Mr Miguel CORSINI (Chairman of UIC) and Mr Brian Crowther (Vice-Chairman of UNIFE) handed over to the European Commission, a copy of Functional Requirements Specifications (FRS) and System Requirement Specifications (SRS) of ERTMS - Class 1.

In February 2002 the revised SRS version 2.2.2 were approved and will be introduced in the TSIs through the Change-Control process managed by AEIF, the European Association for Railway Interoperability. To ensure the full technical interoperability of the system, the UNISIG members decided to introduce amendments. The final agreed version was named Baseline 2.3.0. The specifications currently in force are contained in the version 2.3.0d, which was endorsed by the European Commission in April 2008.

The countries of the EU are now set to pass the necessary laws which will make the use of ERTMS-based signalling solutions mandatory not only on all new high-speed lines, but on all signalling installations.
