Ricardo Certification is accredited by the EU Agency for Railways as a Notified Body (NoBo). In this role, the company is accredited to provide conformity assessments of trains and subsystems against the relevant requirements of the European Interoperability Directives 2008/57/EC and 2016/797/EC. Specifically, Ricardo Certification will verify the new ICE trains in terms of compliance with the current European Technical Specifications for Interoperability (TSI) regulations, including the quality management system of the production process. Preparing DB for the future The new ICE trains will initially run on routes between the state of North Rhine- Westphalia and Munich via the high-speed Cologne-Rhine-Main line, increasing DB’s daily passenger capacity on these mainline routes by 13,000 seats. DB is investing in a strong future proof rail system and plans to expand its fleet by over 20 percent in the coming years.

Looking ahead to the near future, I envisage a transport system that closely meets the needs of its users, that is fast and intelligent but that minimises its environmental impact. The use of high-speed trains shows how this vision for the future can be made a reality today, thanks to the combined efforts of the Member States, partners from the industry and the financial support from the Union.

  • Background Information Siemens Mobility Gmbh Munich, 26 May 2021
    Background Information Siemens Mobility GmbH Munich, 26 May 2021 The ICE celebrates its 30th birthday On May 29, 1991, six ICE 1 trains converged in Kassel-Wilhelmshöhe from different directions and officially inaugurated the era of high-speed rail travel in Germany. The path to this event was paved by a comprehensive phase of research and development dating back to the 1970s conducted by the Federal Ministries for Transportation and for Research and Technology, Deutsche Bundesbahn (today Deutsche Bahn (DB)), and a consortium of companies. The goal of the project, in addition to the systematic research for a suitable wheel-rail system, was the development of a high-speed trainset comprised of two locomotives-like power cars and passenger cars that could reach speeds between 300 and 350 km/h. The power cars were developed by an industrial consortium, led by Krupp Industrietechnik, with Krauss-Maffei and Thyssen Henschel. AEG, BBC and Siemens were responsible for developing the electrical equipment. The Krauss-Maffei locomotive business was acquired by Siemens in 2001. 1985: InterCityExperimental (ICE/V) – Class 410 In March 1985, the aerodynamic power cars of the InterCityExperimental, class 410, were turned over to DB. Together with a measurement car and two demonstration passenger cars, the experimental train began practical testing in 1986. Some of the components were taken over from class 120 locomotives. A new pantograph was developed for the top speeds of 350 km/h. Power cars and passenger cars were braked for the first time with wear-free eddy current brakes and disk brakes, and the power cars were also equipped with regenerative brakes to recuperate braking energy and feed it back into the power line.

  • GBP 235 Million European Investment Bank Backing for 65 New East Coast Main Line Trains
    PRESS RELEASE BEI/14/84 16 April 2014 GBP 235 million European Investment Bank backing for 65 new East Coast Main Line trains Europe’s long-term lending institution, the European Investment Bank has, as part of a consortium of international banks, agreed to finance the deployment of 65 new Hitachi Super Express Trains to be used on the East Coast Main Line between London and Scotland. This new fleet will replace the Intercity 125 and 225 trains currently in use on the line. “Replacing existing Intercity trains on the East Coast Main Line will benefit passengers, increase capacity on the route and significantly cut journey times on one of Britain’s busiest intercity routes. The European Investment Bank is committed to supporting long-term investment in transport infrastructure across the UK and we are pleased to provide a loan of nearly 30 years for investment in new trains to run between London and Scotland.” said Jonathan Taylor, European Investment Bank Vice President. The new East Coast Main Line trains will be financed under the Department for Transport’s Intercity Express Programme, which includes the financing, design, manufacture and maintenance of trains over a 27.5 year operating period. The order for the East Coast Main Line is for 497 new train carriages and the total contract value is GBP 2.7 billion. This is the total value of lease payments train operators will make over the life of the contracts. New trains on the line will include both bi-mode trains, electric trains that can also operate at line speed using diesel engines, and electric trains.

Abstract In the United States, passenger rail has always been less competitive than in other parts of the world due to a number of factors. Many argue that in order for a passenger rail network to be successful major changes in service improvement have to be implemented to make it more desirable to the user. High-speed rail can offer such service improvement. With the current administration’s allocation of $8 billion in its stimulus package for the development of high-speed rail corridors and a number of regions being interested in venturing into such projects it is important that we understand the factors and regulatory structure that needs to exist in order for passenger railroad to be successful.
