3.1. CONDITIONS FOR CLASS B SYSTEMS  
Class B systems for the trans -European rail system network are a limited set of train 
protection and voice radio legacy systems that were already in use in the trans - European rail 
network before 20  April  2001.  
Class B systems for other parts of the network of the rail system in the European Union are a 
limited set of train protection and voice radio legacy systems that were already in use in those 
networks before 1  July 2015.  
3.2. USE OF THIS ANNEX  
This is an annex bas ed on information received from Member States, Norway, Switzerland 
and United Kingdom, and in accordance with the provisions of the provisions of Commission 
Implementing Regulation (EU) 2016/919 of 27 May 2016 on the technical specification for 
interoperab ility relating to control -command and signalling subsystems of the rail system in 
the European Union1 . 
As stated in point 3.1 of the Annex I of this Regulation , “The requirements for Class B 
systems are the  responsibility of the relevant Member State”. De tails on the technical 
specifications can be  found in the RDD.
