久慈川と新芽をイメージした青緑色のラインと扉の黄色が印象的な、水郡線（キハE131形・キハE132形）。郡山市の安積永盛駅から茨城県方面と続くこの路線は「奥久慈清流ライン」という愛称でも親しまれており、 毎年11月中旬ころまで、車窓から紅葉を楽しむことができる。


■Suigun line（KIHA-E131 Type）,which is impressive with bluish green lines across the body, that imaged the Kuji River and a sprout, and yellow door.
This line which spreads out in the Ibaraki area from the Asakanagamori station in Koriyama city is fondly referred as "Okukuji streamline", and until around the middle of November, you can enjoy the autumn leaves from the train windows.
