ERTMS / ECTS Consultancy and Engineering

Enotrac supports railway companies, infrastructure operators and the railway industry with ERTMS and ETCS projects throughout the entire system lifecycle. Our services include studies and feasibility analyses, migration strategies and business cases, system engineering, data engineering, and the integration of ETCS on both the track and rolling stock.

In addition, Enotrac provides support with RAMS management, CSM-RA processes, risk and hazard analyses, V&V, and the verification and certification of ETCS systems.

Enotrac provides comprehensive support for the safety case for ETCS systems and their integration in accordance with the relevant CENELEC standards EN 50126, EN 50716 and EN 50129. Safety case documentation is an essential component of ETCS projects and forms a key basis for the safe integration and authorisation of the systems, as the highest safety integrity level, SIL 4, is required for the safety-critical functions of ETCS.

This support includes, in particular, the preparation of safety plans and safety cases, the conduct of hazard and risk analyses, and the creation and maintenance of hazard logs and safety requirements. Furthermore, Enotrac provides support in the systematic derivation and tracking of safety requirements and safety-related application conditions (SRACs).

In addition to providing technical consultancy, Enotrac can also actively assume the role of Safety Manager within a project. The associated verification and validation roles, as well as the corresponding V&V activities, can also be carried out by Enotrac.

Enotrac also supports its clients in complying with national requirements for safety case documentation. In particular, Enotrac possesses in-depth expertise in the SiNa concept of the ETCS Switzerland system leadership, as well as in the relevant legal framework and guidelines of the Federal Office of Transport (FOT). Compliance with these requirements and specifications forms an essential basis for obtaining authorisations for ETCS systems in Switzerland – for both on-board and trackside applications.

Yes. Enotrac possesses extensive expertise in the independent testing and assessment of ERTMS/ETCS systems and their integration. Depending on the project and the required degree of independence, technical reviews, verification and validation activities, as well as independent assessments, can be carried out.

In the field of independent assessment, Enotrac offers independent expert assessments directly. For formal assessment and evaluation services requiring an accredited body – for example, as an ISA, AsBo, NoBo or DeBo for CCS – the assessment is carried out via our accredited subsidiary SCONRAIL . In doing so, SCONRAIL can draw on Enotrac’s extensive pool of experts and specialist expertise. Assessments can be carried out at product or generic system level, at the level of interoperability constituents, and for integration within the context of a specific application on the rolling stock or specific trackside equipment.

The combination of in-depth ETCS system expertise, RAMS competence and experience with European and national approval requirements enables a holistic assessment of track-side and on-board ERTMS/ETCS applications.

Yes. Enotrac supports rolling stock manufacturers, operators and suppliers with the integration of ETCS into rolling stock, as well as with the associated technical verification and certification. In addition to experienced ETCS experts, Enotrac has a large pool of rolling stock experts, particularly in the field of electrical engineering. The combination of ETCS system expertise and in-depth vehicle know-how enables Enotrac to provide comprehensive support to customers on the various technical and integration-related issues involved in ETCS vehicle integration. This includes the integration of ETCS on-board systems and their interfaces with rolling stock systems, as well as dual-system configurations with national Class B systems, for example via Specific Transmission Modules (STM) or other technical integration solutions.

Enotrac also possesses extensive knowledge of the TSI CCS as well as national authorisation requirements and technical regulations (NNTR/NNTV), which must be taken into account during ETCS vehicle integration and the corresponding authorisation process. Thanks to its expertise in the CENELEC standards relevant to control-command and signalling technology, in particular EN 50126 and EN 50129, as well as its comprehensive RAMS expertise, Enotrac is able to provide optimal advice and support for the ETCS integration process in line with the RAMS V-model. Enotrac also assists its customers in preparing and structuring the technical documentation for the relevant assessment and evaluation bodies, such as ISA, AsBo, NoBo and DeBo.

Enotrac supports you with trackside system engineering, planning and project development for ETCS Level 1 (Limited Supervision) and ETCS Level 2, drawing on experienced ETCS experts who can assist you in defining operational and technical solution concepts, as well as in drawing up requirements for ETCS. Our services range from the preparation of generic specifications based on the desired operational context and national operating regulations to support with specific ETCS track-side equipment projects. In Switzerland in particular, Enotrac possesses not only comprehensive knowledge of the TSI CCS (including relevant subsets) but also in-depth knowledge of the national requirements set by the ETCS Switzerland system authority. Enotrac can, for example, support you with the planning and route design of ETCS in accordance with the applicable design rules and other national requirements.

Enotrac assists with the development of implementation strategies for the phased introduction of ERTMS with ETCS Level 2 cab signalling. This takes into account the current status of track-side and on-board train control and signalling systems, national ERTMS strategies, and future operational and technical requirements.

This support ranges from studies, expert opinions and feasibility analyses, through generic specifications and technical system concepts, to the specific track-side and on-board integration of ETCS. This includes, for example, the planning and implementation of retrofit projects for existing rolling stock fleets, which must be suitably equipped or upgraded for operation on ETCS lines.

Enotrac possesses comprehensive knowledge of the TSI CCS and its further development, as well as the track-side and on-board application of ERTMS and ETCS. This expertise also covers the interaction of ETCS with relevant peripheral systems such as signal boxes – including digital signal boxes based on the EULYNX standard –, Traffic Management Systems (TMS) and Automatic Train Operation (ATO over ETCS).

Furthermore, Enotrac’s experts are thoroughly familiar with national requirements such as the Notified National Technical Rules (NNTR) and other country-specific specifications. This includes, in particular, the specifications set by the ETCS Switzerland system authority, as well as German requirements, including relevant DB specifications and guidelines.

Yes. In addition to traditional consultancy, engineering and assessment services, Enotrac also supports railway companies and the railway industry during temporary resource shortages by taking on specific technical and project roles in ETCS projects.

Experienced Enotrac experts can be integrated directly into existing project organisations and, for example, take on tasks in system engineering, safety and RAMS management, as well as in verification and validation. Depending on project requirements, technical coordination or project management functions can also be undertaken. This allows any gaps in specialist resources and specific expertise to be filled flexibly and on a project-by-project basis.
