The KiHa 283 series (キハ283系) is a tilting diesel-hydraulic multiple unit (DMU) train type operated by Hokkaido Railway Company (JR Hokkaido) on limited express services in Hokkaido, Japan, since 1997. They were based on the KiHa 281 series trains introduced in 1994.
The "KiHa" designation derives from the classification system used by JNR. "Ki" indicates a diesel-powered vehicle, while "Ha" indicates an ordinary passenger car, as opposed to a green car.
KiHa 283 series trainsets have been used on the following services.[additional citation(s) needed]
A three-car pre-production set was delivered from Fuji Heavy Industries in 1995 for evaluation and testing.
20 production vehicles were delivered from 1996, with the first trains introduced on Super Ōzora services between Sapporo and Kushiro from the start of the revised timetable on 22 March 1997.
A further batch of 12 vehicles was delivered to coincide with the introduction of KiHa 283s on Super Hokuto services between Hakodate and Sapporo, operating alongside the KiHa 281 series sets.
KiHa 283 series sets were also introduced on some Super Tokachi services between Sapporo and Obihiro from 11 March 2000.
From the start of the revised timetable on 12 March 2022, all Ōzora limited express services are scheduled to be operated by KiHa 261 series DMUs; the KiHa 283 series DMUs were withdrawn from Ōzora limited express services on 11 March 2022. The KiHa 283 series was reallocated for use on Okhotsk and Taisetsu limited express services on the Sekihoku Main Line from 18 March 2023, operating as three-car sets and replacing the older KiHa 183 series DMUs used on these services.
On 27 May 2011, a 6-car KiHa 283 series train was destroyed by fire after it derailed and made an emergency stop inside the 685-metre-long (2,247 ft) No. 1 Niniu Tunnel on the Sekishō Line in Shimukappu, at around 21:55, while forming the Super Ōzora 14 service from Kushiro to Sapporo. The train was formed as follows, with car 1 at the Kushiro end. All cars were gutted by fire, and were officially withdrawn on 30 June 2011.
