Title Railway applications - Communication, signalling and processing systems - European Rail Traffic Management System - Driver-Machine Interface - Part 5: Symbols
Project Number 13460
Abstract/Scope This Technical Specification describes from an ergonomic point of view how ERTMS information shall be arranged and displayed. This Technical Specification describes more ergonomic details than currently provided by the ERTMS/ETCS/GSM R specifications. This Technical Specification defines the ergonomics for the Driver-Machine Interface (DMI) for the ERTMS/ETCS Train Control System, and for the integrated ERTMS/GSM R Train Control and Train Radio Systems, and for the stand alone ERTMS/GSM R Train Radio Systems and for other technical systems currently provided on the engines. The ergonomics covers the: - general arrangements (dialogue structure, sequences, layout philosophy, colour philosophy); - symbols; - audible information; - data entry arrangements. The aims of the ERTMS/ETCS/GSM R Train Control and Train Radio Systems are standardised systems facilitating interoperable movement of trains and permitting economies of scale in procurement and operations. The objective of this Technical Specification is to define the minimum requirements on the DMI that are necessary to enable these objectives to be achieved. Hence the Technical Specification is limited to ergonomic considerations and does not define the technology to be used for the implementation. The reasons for defining the ergonomics of the DMI are as follows: - achieving harmonised and coherent presentation for ERTMS/ETCS and STM information. Given the large number of STM’s requiring the use the ERTMS/ETCS DMI, only a harmonised approach is feasible. - defining Driver-Machine Interface ergonomics that is compatible with agreed interoperable ERTMS specifications. - to reduce the risk of incorrect operation by a driver working with different trains fitted with ERTMS/ETCS and ERTMS/GSM R. - facilitating train operation with a unified ergonomics, hence reducing the cost of driver training. This Technical Specification is applicable on all trains fitted with the ERTMS/ETCS and also for trains fitted with train radio (GSM R) DMI. The scope of this part of the Technical Specification (Part 5) is to define the symbols used with the ERTMS/ETCS and the ERTMS/GSM R DMI. The actual use of the symbols is depending on the availability of the function addressing the symbol.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
