In response to the growing needs of railway systems, Hitachi, Ltd. is strongly promoting several technological developments which will ensure safe and consistent operation of public transportation agencies, efficient railway business operations, improved customer service, and harmony with the environment.
Examples in the area of rolling stock include the Series 300, E2, E3, and 500 high-speed Shinkansen cars, and the existing line express and commuter cars with better emphasis on comfort, environmental harmony, and economy, as well as efficient drive systems using the most recent insulated gate bipolar transistor (IGBT) technology. Special attention is also being given to linear metros for small bore tunnels, and to monorails as efficient low-cost solutions to the problem of urban transportation.
In the systems area, total systemization centered around the traffic control system is targeted at improving customer service and business efficiency. Also, diligent efforts are underway to develop a new signal system, which is required to rationalize ground operations.
Great expectations are being placed on the idea of railways as environmentally friendly public transportation systems. As a total railway system maker, Hitachi continues to promote technological developments covering a wide range of applications, from rolling stock to electronics, signals, information, and systems.
