The KiHa 122 series (キハ122系, Kiha-122-kei) and KiHa 127 series (キハ127系, Kiha-127-kei) are diesel multiple unit (DMU) train types operated by West Japan Railway Company (JR-West) on the Kishin Line between Himeji and Kōzuki. A total of 19 cars have been delivered, formed as seven single-car KiHa 122 series units and six two-car KiHa 127 series units.[2] Test-running commenced in late September 2008,[4] with the units entering revenue-earning service from the start of the revised timetable on 14 March 2009.[5]
