Railway applications - Signalling and control systems for non UGTMS Urban Rail systems
|Publication Date:||1 April 2020|
|ICS Code (Construction of railways):||93.100|
This document specifies minimum functional requirements for urban rail signalling and control systems:
• which operate on line of sight or using automatic interlock signalling with intermittent train control,
• not covered by the existing UGTMS standard EN 62290 series,
• not forming a part of an urban traffic control system but possibly interfaced with such systems.
The document is restricted to minimum functional requirements which allow users to define more specific requirements based on the given framework of the system requirements at top level. This document is not applicable to command and control systems for urban rail using continuous data transmission and continuous supervision of train movements by train protection profile (already covered by the EN 62290 series).
