Railway electric facilities maintenance starts with monthly patrol inspection.
Inspection is conducted even during the night when the trains are not running.
Mostly, electric substations which transform electricity received from power company by transformer and supply it to trains, and lighting/electric power equipments, such as station lightings or platform digital displays are inspected.
Besides inspection, we do repair work of aging facilities and defects found after the inspection.
We are constantly making efforts together with our partners so that our customers can use railways safely.
