This part of IEC 62290 specifies the functional requirements of UGTMS (urban guided transport management and command/control systems) 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 of trains by onboard UGTMS equipment (reporting trains), and optionally by external wayside (and optionally onboard) device.

In this document, the functional requirements set the framework to which detailed functions are added to define any generic or specific application.

Because of that, although this document is applicable as a basis to define SRS, FIS and FFFIS, elements can be added for a generic or specific application.

NOTE The functional breakdown in this document is consistent with basic functions in IEC 62290 1:2024, Table 1. These basic functions have been refined in this document into a more complete and detailed tree, and the "mandatory/optional" attributes of their subfunctions can be different with those given in IEC 62290-1:2024, Table 1.

The functional breakdown which follows Clause 1 is the reference one for the IEC 62290 series.
