  Railway Technology - ALSTOM - ONIX Invisible Traction Systems and AGATE Electronic Systems 

  http://www.railway-technology.com/contractors/electromech/alstom/

  ALSTOM is the leading supplier of products, services, and systems to both urban and main line rail transport providers around the world. The company offers its customers full ranges of rolling stock and ... equipment, and among the extensive range of products and services available, are our ONIX (traction systems), and AGATE (electronics) product ranges. ALSTOM in transport has over 25,000 employees in over 60 countries worldwide, and annual sales which exceed 3.5 billion Euros. ONIX - THE INVISIBLE TRACTION SYSTEM ALSTOM was the first company to introduce IGBT traction systems to the rail industry. ONIX uses a combination of simplified design and advanced technology, allowing a 50% reduction in volume, a 30% reduction in weight, and a 33% improvement in life cycle costs. In addition, reliability is improved by 50% over the previous generation of traction systems. ONIX s compact, lightweight structure also allows for significant reductions in maintenance costs and energy consumption. The t   [More...] [Less...]

  Science Links Japan | Easy Maintenance and Environment-Friendly Train Traction System 

  http://sciencelinks.jp/j-east/article/200318/000020031803A0557606.php

  Abstract; Hitachi has been developing the converter/inverter equipment, auxiliary power unit, airless line breaker, and electronic master controller by applying the vector control and high voltage resistance ... IGBT (Insulated Gate Bipolar Transistor) for the rapid improvement in capability, maintainability and efficiency. Recently, in the power system of diesel railway cars, the needs to cut-back on maintenance, to increase the efficiency, and to improve the environment are desired. And in the system of electric railwat cars, the compactness and lightness in weight are requested. Therefore, Hitachi has developed the following systems jointly with East Japan Railway Co.,Ltd : (1)hybrid power system which applied the technology of electric system for electric railway cars to the power system of diesel railcar, and 2) small cooling system based on the water circulation system. In addition, the technology which use the speed sensorless control in combination with a full electric brake contro   [More...] [Less...]

  An Introduction to Railway Engineering: The Engineering behind Railroad Systems 

  http://mechanical-engineering.suite101.com/article.cfm/an_introduction_to_railway_engineeringthe_engine

  This branch of engineering developed through the efforts of engineers and railroad companies to make railway systems safer, more reliable, more powerful, and more cost efficient. Railway engineering has ... evolved into a diverse profession, requiring talents in a number of Historically, railway engineering was strictly a mechanical engineering discipline, encompassing pressure vessel design, purely mechanical vehicle components, and hand-powered switches. However, railway engineering has become more reliant on electronic systems, specifically control and communications. As an example of this interdependence, the Rail Transportation Division of the American Society of Mechanical Engineers (ASME) and the Institute of Electrical and Electronic Engineers (IEEE) hold a joint conference each year to discuss advances in railroad-related research, development, and testing. Railway Engineering Disciplines Railway engineering contains many sub-disciplines, including: Vehicles – This division includ   [More...] [Less...]

THE DEVELOPMENT, PRODUCTION and maintenance of diesel traction systems for railway trains are among MTU's core capabilities--and have been for nearly 100 years. As long ago as 1924, the company was developing and manufacturing production engines for scheduled service trains. In 1933, its diesel engines provided the motive power for the legendary Fliegende Hamburger, the first high-speed railcar. And from the early Fifties through to the Seventies, MTU supp   [More...] [Less...]
