JR West KiHa 120
Japan 1991 89 produced
To replace aging diesel railcars built in the sixties in service with small third sector operators, JR West introduced the KiHa 120 in 1991. This is a small four-axle railcar with a total length of only 16.3 meters. Power comes from a Komatsu SA6D125H-1 six-cylinder diesel producing either 250 or 330 hp depending on variant. Both axles of one bogie are being powered via a hydraulic transmission. There are three variants called 120-0, 120-200 and 120-300, which differ mainly in the interior. A total of 89 railcars were built by 1996. One has been retired after an accident and the refurbishment of others started in 2017.
