This document specifies minimum functional requirements for urban rail signalling and control systems (for use in urban guided passenger transport lines and networks)
– which operate on line-of-sight or using automatic interlock signalling with intermittent supervision,
– not covered by the existing UGTMS standard IEC 62290 series, and
– 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 IEC 62290 series).
