About Railway & Machinery Engineering Division

  1. Feature
    Our technology started under the mission - support the Japanese artery.
    We inherited technology of Sumitomo Metal Industries, Ltd., which has walked along the progress of railway industry from the beginning of 20th century and participated to the development of the railway cars for Shinkansen of which Japan can boast to the world.
    For that reason, our Railway & Machinery Engineering Division can provide technology widely covering various tests, evaluation and maintenance for railway car and track system, and also sales of the related equipment.
