DIN CLC/TR 50542-1:2025-12

In accordance with the ERTMS/ETCS specifications (mainly Subset 026 and ERA ERTMS 015560 document), UIC 612 leaflet, EN 50126 (series), EN 16186 (series) and EN 61375 (series) requirements, this Technical Report describes the Train Display System (TDS) in the driver's cab which comprises the Train Display Controller (TDC) and the following six interfaces: - Interface with Command Control Display (CCD), - Interface with Train Radio Display (TRD), - Interface with Electronic Timetable Display (ETD), - Interface with Technical and Diagnostic Display (TDD), - Interface with ETCS Onboard systems and the interfaced STMs, which is excluded from the scope of this document, - Interface with Other Onboard Systems. The scope of this document is to define the functional architecture around the (TDC). This document excludes the following items: - Communication protocols (for example, EN 61375 series); - Ergonomic aspects; - Interface with ETCS Onboard systems and the interfaced STMs; - Train functions; - GSM-R EIRENE functions; - Use of the displays as terminals for maintenance purpose. The standard differs from DIN CLC/TR 50542-1 (VDE 0115-542-1):2019-05 as follows: a) Clause 6, "Communication", has been revised; b) in Clause 7, "Safety Targets", Table 1, "Table 1 - Design Practices", has been revised and supplemented; c) Annex A, "Relations between the functions described in the documents of the CLC/TR 50542 series", has been revised. DIN CLC/TR 50542-1 (VDE 0115-542-1):2025-11 is typically used when integrating multiple displays from different manufacturers into the driver's control panel, in the modernization or new development of traction vehicles, and in order to ensure interoperable communication between display and train systems.
