Keisei Electric Railway Co. said Saturday it has fully resumed services in the Tokyo metropolitan area after a suspension of over 10 hours the previous day due to an outage believed to have been caused by typhoon-borne salt.
Several power cables caught fire, possibly because of dried salt water on them on Friday morning, resulting in the outage and halt of train services on all lines.
The railway operator believes seawater was carried inland by Typhoon Trami, which swept through Japan last week. The Keisei line connects the capital and Narita airport, a main international gateway to Japan.
