本動画の気仙沼、盛駅間は、鉄道による復旧が断念され、BRT(Bus Rapid Transit; 専用線を用いたバス輸送)化されました。
Kesen'numa Line of Higashi Nihon Railway Company(JR East) used to connect between Ichinoseki and Sakari, which is a port town along the pacific ocean. In 2011, the part of the railway between Kesen'numa and Sakari stations was severly damaged by the Higashinihon Great Earthquake, and significant part of the railway was washed out by the great tshumami. In 2013, this part was recovered as a BRT(Bus Rapid Transport), we can not see trains here no more.
