Railway facilities are newly built or renovated to improve convenience of customers, optimize railway operations, or meet technological advances.
For these constructions, we need the drawings illustrating how to build or renovate the facilities.
Railway facility design is to create drawings and construction documents after sorting out construction concepts and knowing the on-site conditions through discussions with railway companies. We mostly do design of the substation and the electric light/power facilities.
