OVERVIEW: The Gran Class is the first new grade of passenger car to be introduced since the Shinkansen began operating. Its design needed to provide not only a luxurious interior, but also an extraordinary experience that would justify the additional cost of a premium seat. Hitachi had collaborated with the East Japan Railway Company to develop the design of the new Gran Class passenger car for the E5 "Hayabusa" used on the Tohoku Shinkansen. The aim was to provide an unprecedented travel experience. The initial design work involved visualizing how passengers would use the car. This was followed by the formulation of scenarios covering different travel experiences that were then used to determine passengers' latent requirements and subjective values. The final step was to develop the style of service and interior that would satisfy the requirements identified from the scenarios. In producing this design for an unprecedented premium passenger car, Hitachi found that it needed to trial a variety of different methodologies and to utilize manufacturing techniques with a high degree of craftsmanship.

As a manufacturer of rolling stock, Hitachi has developed and produced rolling stock for high-speed and commuter trains in Japan, and has made numerous advances in railway technology to satisfy a wide range of needs. The total number of Hitachi's A-train rolling stock supplied in Japan has already passed 2,000, and development is ongoing in response to new requirements, including energy efficiency measures such as the use of LED lighting. For the UK market, to which Hitachi gained access through the development of the Class 395 trains for that country's High Speed 1 line that commenced commercial services in December 2009, Hitachi has built the AT-100, AT-200, and AT-300 platforms that feature greater compliance with standards, has developed a lightweight carbody for local manufacturing and lightweight inner frame bogies, both of which are key components, and has made progress on optimizing rolling stock information and control systems as well as the traction system.

With energy efficiency becoming increasingly important in recent years, demand is growing for the adoption of LED lighting as a replacement for fluorescent interior lighting in passenger trains. Rather than simply replace fluorescents with LED lighting, Hitachi has drawn on its experience and past activities as a manufacturer of rolling stock to achieve power savings of 40 to 60% while also taking account of interior design considerations and the color of the light. Hitachi has also succeeded in approximately halving life cycle costs compared to existing generalpurpose LED lighting through measures that include adopting a dedicated power supply and designing long-life circuits. In the future, Hitachi intends to continue development with the aim of adopting LEDs for train headlights and other lighting with systems that further enhance the functions of LED lighting for passenger train interiors.

OVERVIEW: Railways play an important role in Japan and the country has well-developed railway services both in its major cities and on inter-city routes. Railway services have evolved in part as a way for people to commute to work or school and mission-critical systems have been implemented to support railway operations and ensure that services are punctual even during the morning and evening rush hours when train operation timetables are particularly busy. Coordination between these mission-critical systems will also be a requirement for the ongoing future development of railway services. We intend to continue contributing to the development of social infrastructure through railway systems by supporting, across different systems and different railway operators, services that provide links to other communities and are part of the social framework through the convergence of information and control technologies we have built up over many years and by strengthening their role in a service platform.
