1   Scope

  This part of [IEC 62290](/search?q=IEC%C2%A062290)
   specifies the system architecture for urban guided transport management and command/control
  systems (UGTMS) as defined in [IEC 62290‑1](/search?q=IEC%C2%A062290%E2%80%911) and [IEC 62290‑2](/search?q=IEC%C2%A062290%E2%80%912), and the allocation of functions and requirements defined in [IEC 62290‑2](/search?q=IEC%C2%A062290%E2%80%912) to the different UGTMS subsystems (designated as system constituents in [IEC 62290‑1](/search?q=IEC%C2%A062290%E2%80%911) and [IEC 62290‑2](/search?q=IEC%C2%A062290%E2%80%912)), for use in urban guided passenger transport lines and networks. 
This document is applicable for new lines or for upgrading existing signalling and
  command control systems. 
This document is applicable to applications using 

   
      
         

• continuous data transmission,

• continuous supervision of train movements by train protection profile, and

• localisation by onboard UGTMS equipment (reporting trains), and optionally by external wayside (and optionally onboard) device.

The functional allocations of the UGTMS subsystems are mandatory (forming a sort of
  core system) or optional, according to the mandatory/optional functions and requirements
  defined in [IEC 62290‑2](/search?q=IEC%C2%A062290%E2%80%912). 
This document is applicable as a basis to define FIS and FFFIS. For specific applications,
  some elements can be added to meet the requirements coming from additional functions
  or equipment.
