Changing the Needs into Reliable Technologies

Railway is advancing day after day in a safer, more comfortable and more people- and environment-friendly manner. In order to change a wide range of needs for railway into reliable technologies, our Research and Development department is proactively addressing practical use of 2-step-gradient pressure welded crossing, building of design system for turnouts with steel sleepers, development of low-noise crossing and LED-based crossing indicator, and development of Goldsummit welding technique in concerted efforts with our customers.
