OSAKA -- The Tokaido Shinkansen Line linking Tokyo and Osaka ground to a halt Thursday morning after an icicle shorted out a power line, Central Japan Railway Co. (JR Tokai) said.

The incident occurred near the Otowayama Tunnel on the Kyoto-Shiga prefectural border.

Tokyo-bound bullet trains were suspended between Kyoto Station and Maibara Station, in Shiga Prefecture, from the start of the day's services until 7:55 a.m.
