On Tuesday 25 th 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.

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

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.
