The KiHa 122 series (キハ122系 Kiha-hyaku-nijūni-kei) and KiHa 127 series (キハ127系 Kiha-hyaku-nijūshichi-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]
Exterior
The body design features improved crash resistance, based on the recent 223 series electric multiple unit design. The cars use environmentally-friendly diesel engines with reduced NOx and particulate emissions.[6]
Externally, the units are finished in unpainted metal with thin yellow and red waistline stripes.[4]
Interior
Internally, the cars feature flip-over reversible seating arranged 2+1 abreast. Toilets in both types of train are wheelchair-accessible, and the step between the passenger compartment and station platform has been eliminated.[6]
