Five train lines in western Tokyo that had suspended operations Tuesday night after a severed railway cable caused a fire in the city of Tachikawa resumed services Wednesday morning.

Services for the five train lines — including the entire JR Ome and Itsukaichi lines, sections of the JR Nanbu and Hachiko lines, as well as parts of the Seibu Haijima Line — had been halted Tuesday night. The Seibu line was affected because East Japan Railway Co. supplies it with electric power.

At about 7:40 p.m., a Tachikawa resident saw a burning cable under a section of tracks and called the fire department. The fire was extinguished a little past 10 p.m. The cable was used to power train stations and to send signals. The fire caused a power cut that affected 79,000 passengers.

JR East is investigating the cause of the fire.

A 55-year-old woman from Akishima, western Tokyo, said she was on a train that stopped between Nishitachikawa and Tachikawa stations.

"The air conditioning stopped, the lights went out, and we were stuck there, standing, waiting for power to be restored for two hours," she said Tuesday night, looking tired.

"I want to go home quickly as I have an early day tomorrow."
