- About TRIP
The current interoperability approval process for new High Speed and Conventional railway vehicles in Europe is a very long and costly process. The European Railway Agency (ERA) is charged with the development of new and future Technical Specifications for Interoperability (TSIs), which provide common regulations for the authorisation of the placing into service of new vehicles. TSIs will provide a safe and technically-compatible railway system for Europe by specifying requirements for all relevant technical aspects. However, they will not directly eliminate the burdens that currently affect the railway industry and the railway undertakings regarding new vehicle approval on each national network in Europe.
TSIs are a set of common minimum requirements and therefore not optimal for every network administrator and/or railway undertaking. Placing in service a new vehicle, even if compliant with TSIs, still requires network approval by each National Safety Authority(NSA) responsible for the Member State in which the vehicle is to be operated.
In addition to the handicaps mentioned above, it is important to take into account the lack of compatibility of the national assessment methods. Therefore it is often requested by the Member States to repeat specific tests for homologation that are analogous to those tests already performed in other countries. At present a full harmonisation of the assessment methods required does not exist, although the evolution of new and expanded European standards is helping to close the gap.
AeroTrain will help meet the business scenarios listed in the ERRAC (SRRA 2002 and 2007) by aiding the spread of European homologation and acceptance procedures to speed up interoperable product approvals while squeezing out risk through improved safety management. In the field of aerodynamics a recent European standard (EN) focuses on common definitions and descriptions of the aerodynamic phenomena and measurement procedures. Due to its application for all types of rail traffic it has not converged yet to one method per phenomenon but allows variations arising from national rules. The focus of the project is therefore on using the TSI route to consolidate the methodologies allowing the free exchange of certification data.
The network approval of multi-system vehicles is a key subject that can and must be addressed in order to provide a competitive railway system within Europe. Therefore, the importance of AeroTRAIN, as it will contribute to the practical implementation of interoperability across Europe by leading to a faster, cheaper and better certification and authorisation process for all involved stakeholders.
The AeroTrain project is part of the TRIO-TRAIN cluster (Total Regulatory Acceptance for the Interoperable Network) which comprises three related projects dealing with key railway interoperability issues: Aerodynamics (AeroTRAIN), Railway Dynamics and Track Interaction (DynoTrain) and Pantograph/Catenary Interaction (PantoTrain) all submitted under the 2nd Call of FP7.
The overall goal of the project AEROTRAIN is to promote interoperable rail traffic in Europe by reducing costs and time of certification and closing "open points" in the TSI's. It will be achieved by the following high-level objectives:
Technical objectives and expected results:
On the basis of the requirements for the new CR TSI and revision of HS TSI, opportunities to reduce certification costs and, where it is seen that virtual certification could be introduced, it is decided to focus the study on five main aspects of rolling stock aerodynamics that are or need to be subject to certification. Hence the Work Program of the project is organised around five technical Work Packages:
Open Air-Pressure Pulse:
Aerodynamic Loads on Tracks - to define and agree on:
Train - Tunnel Interaction:
Slip Stream Effects:
Dissemination and ensuring the acceptance of the results of the project by European and National Safety Authorities. Methodologies will be defined to be applied to all the procedures developed in the other WPs in order to check and guaranty the quality of the results and propositions.
The project will bring a procedure for virtual certification of head pressure pulse valid for streamlined and non-streamlined trains, including the applicability of inviscid panel methods, and a verification that the maximum peak-to-peak pressure change occurs at the head of the train.
AeroTRAIN will establish common vehicle requirements to derive dimensioning guidelines for CR RST with respect to aerodynamic loads in tunnels, and set up a TSI criterion regarding micro-pressure waves (MPW) for interoperable trains to limit MPW effects in tunnels
Expected results on slip stream effects are the development of a transfer function which will enable measurements made at one location (e.g. at the trackside) to be related to those at a different location (e.g. on the platform); and a reduction in the technical requirements concerning the evaluation of slipstream velocities and hence an increase in the integration of rail transport activities across the EU.
The AeroTRAIN project will introduce:
The main innovation brought by AeroTRAIN with regards to aerodynamic loads on tracks are the following:
