Technical R&D Lab.

Railway is advancing day after day in a safer, more comfortable, more people- and environment-friendly manner. In order to change a wide range of needs for railway into reliable technologies, Technical R&D Lab. proactively challenges practical use of a two-step gradient pressure-welded crossing and turnouts with steel sleepers, development of movable crossings, and LED-based crossing indicators, as well as Goldsummit welding technique in concerted efforts with our customers.
