Innovative modular vehicle concepts for an integrated European railway system

Exploitable results

A highly technical project, Modtrain provided the high speed market a set of specifications that allow for better inter-changeability of key components for maintenance, as well as for a higher level of standardisation at the interfaces of the main train subsystems. This was achieved through the identification of the main interfaces subject to possible standardisation and the drafting of the related standards. This problem was addressed by breaking down the four principal areas of a train's architecture - running gear, train control and monitoring system, on-board power system, man-machine and train-to-train interfaces - into four tasks, or 'outputs'. - Modtrain's first main output consisted of building a common architecture stemming from an analysis based on functional breakdown structure, and the subsequent allocation of functions. All train functions were included. - The next main output of the project was the elaboration of the functional requirements of the sub-systems and building of a harmonised requirements database. - The third main output was the identification of the main modules and the set of common interfaces specifications.5L- The fourth main output was the devising of a set of inputs for future EN standards and technical specifications for interoperability. This output was based on both draft standards agreed upon by the railway industry and operators, and on new concepts tested for modules and interfaces by means of simulation/testing/mock-up methodologies. Modtrain's technical breakthroughs provided a proven set of functional, electrical and mechanical interfaces and validation procedures to deliver the range of interchangeable modules, which will form the basis for the next generation on intercity trains and universal locomotives. Expanding on this at an operational level, some of Modtrain's technical results (module and interface specifications) are at present in the pipeline of the European Standardisation Organisations (CEN / CENELEC) to become future European norms. Modtrain expands on the EU's previous legislative packages that were set out to support the rail sector and increase its competitiveness. In these packages, the Commission developed the Interoperability Directives which set essential requirements, so as to ensure safe and uninterrupted rail traffic on the Trans-European network. Taking a step further, Modtrain is also paving the way for a new type of cooperation between the different actors of the sector. Beyond the mandatory requirements set in the European regulations, Modtrain proves that voluntary harmonisation is feasible and is contributing to the objectives of greener, safer and faster trains for Europe.
