The KiHa 122 series (キハ122系) and KiHa 127 series (キハ127系) 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]
