- W1542220541 abstract "Work to improve the performance of high speed trains produced only modest results until the Japanese National Railway was split up in 1987. Since then, journey times have been reduced and the latest experimental trains have speeds approaching 400 km/h. The author traces the history of the development of the high speed lines and assesses the future prospects. From March 1993 trains will cover the 515 km journey between Tokyo and Osaka in 2hr 20mins, whilst an hourly service will take just over 5 hrs to travel the 1069km to Hakata or Kyshu with six intermediate stops. Commercial demands are for faster journeys, energy economy, greater comfort and more capacity without increasing lineside noise. Major improvements have been achieved by the use of asynchronous A C motors, with a unity power factor during motoring and regeneration, and shapes of low aerodynamic resistance. Significant reductions in the weight of traction equipment has been achieved in the latest versions and they use fewer pantograph which are shielded to minimise noise generation. Future projects include a possible maglev line with potential operating speeds of up to 500 km/h. A double-deck train is being investigated to meet the increasing demand for long distance commuting to Tokyo." @default.
