Enhancing Safety Technologies in Line with the Increasing Speeds of Rail Transportation

Railroad Vehicle Equipment

As a world-class high-speed railway system, the Shinkansen represents Japanese know-how at its best. Because the speed of these trains exceeds 300 kilometers per hour, the technology used to control them needs to ensure absolute safety and reliability. As part of our commitment to making technological contributions to the safety of high-speed rail transportation, Nabtesco has been developing Shinkansen brake systems and door operating units, both of which are core components of the trains. Our high-standard technologies are widely adopted not only in the Shinkansen but also in local trains and new transportation systems. Furthermore, railway operators have recently been increasingly intent on reducing the size and weight of machinery and equipment as larger cabin space and environmental measures become more important. In order to help their trains run faster and more comfortably, Nabtesco is currently developing technologies to boost the evolution of rail transportation.
