The fundamental concept of the ubiquitous information society is the ability to obtain needed information whenever and wherever one wants. In the context of enhanced railway passenger services, this means above all providing passengers with access to the network anytime and anywhere whether in railway stations or on-board trains. Equally important considering the greater intelligence of railcars themselves, is the need for more advanced on-board operating systems that are seamlessly connected to track-side systems. As a comprehensive rail system integrator, Hitachi has responded to these needs and at the same time contributed to more convenient and efficient rail systems through the development of a sophisticated broadband network system for trains —dubbed the B-system— that not only significantly increases the capacity of on-board networks but also supports seamless continuous interconnection between on-board and track-side systems.
