Trains could not run safely without signaling systems. Hitachi, Ltd. has been an industry leader in the development of general-purpose computerized interlocking systems, digital ATP systems, and other innovative products supporting railway signaling systems that provide the highest standard of safety and reliability. Recent initiative has focused on the development of an integrated signaling system called SAINT that combines previously separate interlocking and ATP systems to achieve greater efficiency, space savings, and cost efficiency. Implemented for the first time by leveraging all the company's previous technology and expertise, SAINT represents the culmination Shinkansen signaling system. Never content to rest on its laurels, Hitachi is committed to day-to-day progress in developing new technologies to meet the needs of railway operating companies and to contribute to society at large.
