DIN EN IEC 62290-3:2026-03

This document specifies the system architecture for urban guided transport management and command/control systems (UGTMS) as defined in IEC 62290‑1 and IEC 62290‑2, and the allocation of functions and requirements defined in IEC 62290‑2 to the different UGTMS subsystems (designated as system constituents in IEC 62290‑1 and IEC 62290‑2), 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. 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. 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. It should be noted that the allocation work carried out in Clause 6 made it possible to identify potential communication links to external devices via the DCS, but this document does not cover all of the possible communication links. The standard differs from DIN EN IEC 62290-3 (VDE 0831-290-3):2020-10 as follows: a) the last maintenance of IEC 62290‑1 is taken into account, in particular the changes made for describing the external environment of UGTMS; b) the last maintenance of IEC 62290‑2 is taken into account, as IEC 62290‑3 is using the requirements defined in the latter. Therefore, the document reflects the deleted functions and requirements in IEC 62290‑2, and also the new functions and requirements. 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.
