This European Product Standard specifies the characteristics of operational and technical requirements for the overall system design as well as safety acceptance and approval, maintenance, modifications and extensions of the radio remote control system for the use in railway network in relationship with other European Standards. This European Product Standard applies only for the use of radio remote control systems for freight traffic. If the radio remote control system is modified in such a way that the system safety may be compromised it is necessary that safety reviews are carried out throughout the system lifecycle. This European Product Standard is not applicable to existing systems (i.e. those which had already been accepted prior to the creation of this standard). However, as far as reasonably practicable this European Product Standard applies to modifications and extensions to existing systems.
