1. Partners

The contract (RA-95-SC.101) was managed by the European Economic Interest Group (ERTMS Users Group). The group, at the initiation of the contract, consisted of personnel from the 3 railways; namely DB, FS and SNCF along with some specialist contract personnel. During the course for the contract 3 other railways namely NS, RENFE and Railtrack joined the EEIG. The amendments to the contract brought in industry as "Associated Contractors" to develop the Specific Transmission Modules. The full list of partners is listed below.

Deutsche Bahn AG ("DB")
Ferrovie dello Stato S.p.A ("FS")
Société Nationale des Chemins Fer Francais ("SNCF")
Ansaldo Trasporti - Central Research Department ("ATR")
Ansaldo Segnalamento Ferroviario S.p.A ("ASF")
CS Transport ("CST")
ABB Daimler-Benz Transportation Signal AB (ADTRANZ)
Sasib Railway S.p.A (now Alstom Italy)
GEC Alsthom Transport S.A. ("GATSA") (now Alstom France)
Alcatel SEL AG ("SEL")

2. Objectives

The project is part of an overall strategy to aid and encourage interoperable train control systems within the spirit of the Directive 91/440. The project, managed by the EEIG, under the 4th framework programme consisted of 2 major elements. Firstly development of the specifications and secondly realisation of testing sites and equipment.

The first phase was aimed at developing a comprehensive range for user, technical and test specifications including the elements required by Euro Norms for RAMS and Environmental conditions. Also included were the development of a range of common test tools and their specifications. System prototyping was to be accomplished by the individual companies with the exception of the Specific Transmission Modules (STMs) which were contracted in the 2nd amendment. The contract also covered some preliminary customisation activities for the pilot sites.

The overall objective of the project was to prepare the full scale ERTMS performance and interoperability trial tests. These tests which are out of the scope of this contract are foreseen in three tests sites located respectively in France, Germany and Italy.

3. Short Technical Description

ERTMS/ETCS, which basically uses a target distance - target speed concept, must be designed to be extendible in order to suit the various needs defined in the Functional Requirements Specifications (FRS), from simple speed monitoring and speed control by balises to high performance moving block systems, simply by adding technical modules or software functions.

The main objectives of overall ERTMS/ETCS project can be summarised as:

  • Achievement of interoperability.
  • Standardisation of train control functions and exchange of information.
  • Allowance for gradual implementation.
  • Allowance for different levels of application according to performance and needs.
  • Achievement of a higher safety and reliability than current signalling system.
  • Definition of: - the external interfaces and standardisation.
  • the standard communication means.
  • Interfacing to existing national systems by modules able to receive their information and translate it into ERTMS/ETCS formatted data.

Achievement of the optimum cost effective solution, significantly lower costs for buying installing and maintaining operation than for other existing systems. The first part of the programme for which the EEIG was responsible according to this contract is shared in 2 parts:

  1. The completion of the specification of ERTMS system, the specification of the trial sites and the specification of the tests which will be carried out in order to prove the feasibility of the system; this stage was finished with the call for tenders which will start the manufacturing phase of the project.
  2. The demonstration of the feasibility of the different ERTMS components through functional modelling.

The ERTMS Users Group members and some specialised contract staff undertook the specification of the system. An industry consortium was contracted to produce some sub system specification and interface specifications.

The development of the STMs was prompted by recognition of the need for ERTMS fitted trains to run on existing national trackside infrastructure. The STM receives information from the existing trackside system and produces an output that can be used by the ERTMS on-board system. The STM contract asked for each of the Associated Contractors to develop a prototype, which would then be tested later in the overall ERTMS project.

4. Results and Conclusions

At the centre of the specifications is the System Requirement Specification (SRS). The SRS references all the other applicable specifications and describes how the system operates, it's language and its requirements for safety and reliability.

A comprehensive range of test requirements was also produced. These will be used to verify the system.

After each stage in the production of these documents a validation was carried out, and the final specifications were subject to a safety analysis. This analysis includes preliminary hazard identification on all the system functions.

During the course of the contract the railways involved initiated a call for tender to industry for the manufacture of the system using the specification provided by the EEIG modified to suit the individual railway.

All the output documents for the specification phase have been issued to the relevant parties on CD-ROM and will be in the public domain.

STM prototypes have been produced for the following national systems under the contract
BACC and RSDD
KVB and TVM
Indusi and LZB

The scope of the contract was to prove the feasibility and prepare test for the ERTMS system concept, later including a provision to develop the STM. The result was that the specifications have been drawn up, contracts placed based on these specifications and STM prototypes developed. The tests have been prepared and will be carried of at the National Trial Sites and at EMSET, the interoperability test site. The conclusion being that the contract has been carried out successfully.

5. Collaborations sought

The ERTMS Users Group has enlarged it's membership during the course of the contract, although not partners in this contract, Netherlands Railway (NS) Spanish Railway (RENFE) and the UK Railway infrastructure owner Railtrack have joined the three founding members, DB, FS and SNCF.

In terms of the usage of the results, each participating railway has access to the relevant specification and aside from the 3 trial sites, contracts for commercial lines are planned by DB, FS, Railtrack, NS and RENFE. Outside the ERTMS Users group, but involved with the overall project, Swiss Railways (SBB) has initiated a contract with an industry consortium for a commercial implementation of a Level 1 system.

6. Exploitation and dissemination plans

The Technical Specifications for Interoperability (TSIs) are mandated by European Directive for Interoperability. The TSI for "Control and Command" will define the overall system in terms of its mandatory and advisory internal interfaces and it's interfaces with other TSI. Essentially it will point to the other specifications, system, safety, quality etc to enable authorities to certify the system. It is planned that the referenced document will be CENELEC standards. These have yet to be produced but the ERTMS specifications will be used as an input to the process. In this way the specification work carried out under this contract will be placed in the public domain under a recognised authority. This will allow European railways to place contracts with industry on the basis of a European specification.

The STM contracts called for the production of prototype STMs and delivery of STM specifications. This was completed, however, the production of commercial product will depend on market conditions and the strategy of each national railway. The STM is a transitional technology designed to allow trains fitted with ERTMS to use train paths fitted with a national system. Therefore, as it is anticipated the Trans European Rail Network will become standardised with ERTMS, the exploitation of STM will be the concern of the national railways.
