42 Technical Meeting of the Institution held at The Institution of Electrical Engineers, London WC2 Tuesday 10th December 2002 The President, Mr P W Stanley, in the chair. 71 members and visitors were in attendance. It was proposed by Mr J Tilly, seconded by Mr D McKeown and carried that the Minutes of the Technical Meeting held on 6th November 2002 be taken as read and they were signed by the President as a correct record. The President reported that Mr B Grose, who had for many years summarised the discussion at technical meetings for publication in the Proceedings, had resigned from the honorary office of Assistant Papers Editor and a replacement was being sought urgently. Any member wishing to volunteer to take up this important role for the Institution should kindly inform the office. Mr Jason Lo, of Alstom, was present for the first time since his election to membership and was introduced to the meeting and welcomed amidst applause. The President then introduced Mr C Frerichs, of Siemens Transportation Systems, and invited him to present his paper entitled “EuroCab and the Driver MMI”. Mr Frerichs illustrated his presentation with computer slides and explained the principles of EuroCab and the Driver MMI giving examples from the Siemens product range. Following the presentation Messrs C H Porter, IRSE; P Wiltshire Cenelec SC9XA Committee; P Bassett, AEA Technology; P Vandermark, Driver First GW; K Molt, Thales; D Woodland, Bechtel; I Mitchell, AEA Technology; and J Lo, Alstom, took part in the discussion. Mr Frerichs dealt with the questions in a comprehensive manner. The President then proposed a vote of thanks and presented the speaker with the commemorative plaque customarily awarded to authors of the London paper. The President then made announcements of forthcoming events and closed the meeting by announcing that the next meeting in London would be held on the 15th January 2003 when Mr I Mitchell will present a paper on “Signalling Control Centres”. Eurocab and the Driver MMI – an introduction to the technology Christian Frerichs 1 ABSTRACT ERTMS/ETCS consists of two subsystems: the trackside subsystem and the on-board subsystem. The latter is dealt with in this paper. Legal and technical requirements relevant to the ERTMS/ETCS onboard subsystem and its system architecture are described. Requirements for integrating ERTMS/ ETCS onboard subsystems into vehicles are highlighted, and typical architectural designs are presented. Within the ERTMS/ETCS architecture, special attention is drawn to the Driver’s MMI, which is the key component for system operation. The Siemens ERTMS/ETCS Onboard System, being one of the most progressive and state-of-the-art solutions, is presented and its benefits are highlighted. INTRODUCTION With the ongoing introduction of ERTMS/ETCS (European Rail Traffic Management System/ European Train Control System), Europe is on its way to overcoming a long history of railways having their own, proprietary ATP/ATC systems, so preventing cross-border traffic and an open market. The system is being introduced both in law – by EC directive 96/48 1 and the underlying TSI Control Order 2 – and in practice by utilising it in pilot sites like the German Berlin–Halle/Leipzig project and in commercial projects like the new Spanish Madrid–Barcelona line with its demanding 350 km/h service. ERTMS/ETCS is an ATC system consisting of trackside and onboard subsystems. The trackside subsystem, although clearly governed by the specifications referenced in the TSI, allows great 1 Siemens Transportation Systems, Ackerstrasse 22, D-38023 Braunschweig, Germany freedom in realisation, which is a tribute to the need to adapt to existing infrastructure (apart from the fact that trackside solutions for Level 1 and Level 2 are different). The onboard subsystem however is governed to a much greater extent by European (TSI referenced) specifications, with mandatory functionality and mandatory interface requirements. The purpose of this paper is to give an introductory presentation of the specifications and implementations of the ERTMS/ETCS onboard subsystem. The ERTMS/ETCS onboard subsystem is also known as Eurocab, an expression that is slightly outdated as it is no longer used in the current ERTMS/ETCS specifications. A core element of the onboard subsystem is the Driver-Machine Interface (Driver MMI or DMI), because it is the interface between the technical system and the train driver. LEGISLATION AND SPECIFICATIONS GOVERNING ERTMS/ETCS In 1996 the Council of the European Community issued Directive 96/48 1 . This contains guidelines for an interoperable trans-European high-speed rail network, in the form of standards in respect of technical facilities and railway operation. This directive has since been adopted into national law by the EU member states. Meanwhile it has been complemented by a directive which mandates interoperability on conventional lines as well 3 . Directive 96/48 1 is supplemented by the Technical Specifications for Interoperability (TSI), which describe requirements and features which are to apply to those technical systems affected by interoperability demands, eg the control, command and signalling system 2 . The latter references the actual technical specifications according to which the technical system has to be designed and implemented.

The core document of these specifications is the System Requirement Specification (SRS) 4 . The SRS has undergone a debugging process since then, leading to a revised version 2.2.2 5 which is now referenced in the TSI and which is, together with the other ERTMS/ETCS specification documents, mandatory for implementation of the system. Table 1 shows the main documents relevant to implementation of the ERTMS ETCS onboard subsystem. The Functional Requirement Specification (FRS), being a functional specification, does not specify any technical solutions and is therefore only marginally relevant when implementing a system, and the SRS is the key document for this. It describes the architecture and functionality of the system and the ETCS language, and it is the source for all other documentation. Although it is a specification for the whole system, it includes the onboard subsystem. The SRS is accompanied by a set of supplementary specifications, such as performance requirements etc, and by interface specifications. There are two kinds of these: Functional Interface Specifications (such as the FIS for the Man-Machine Interface) which specify only the logical interface, and Form-Fit-Functional Interface Specifications (such as the FFFIS for Eurobalise) which prescribe physical features of the interface as well. All the above specifications are mandatory, but this is not the case for the ergonomic layout of the DMI, which is specified in the ERTMS Driver Machine Interface Specifications (parts I-VI). It must be emphasised that the specifications govern only those features of the system that are relevant to interoperability. This means that features that do not affect interoperability (e.g. diagnosis) are not described, and are at the discretion of the manufacturer. ERTMS/ETCS ONBOARD ARCHITECTURE AND FUNCTIONALITY ERTMS/ETCS is an ATC system with an onboard and a trackside part, and there is a clear interoperability requirement between these even if they are supplied by different manufacturers. Therefore the interfaces between onboard and trackside subsystems, and also the partition of system functionality between onboard and trackside, must be specified very thoroughly. On the other hand the concept of interoperability includes specifying only to the extent that interoperability is affected. This leads to a system concept different from what was discussed at the start of the history of ETCS, when a concept of exchangeability of components was on the table. The actual ERTMS/ETCS specifications are based on a blackbox concept, with clearly defined functionality and interfaces but with maximum freedom to design onboard and trackside equipment. Figure 1 shows the ERTMS/ETCS system architecture. The onboard subsystem is depicted in the upper part. As mentioned above, the onboard subsystem is a black box with the following interfaces: • Train Interface (TIU) – eg to brakes, traction control, air conditioning, etc. • Driver MMI.
