History

The Okhotsk service was first introduced by Japanese National Railways from the start of the revised timetable on 22 September 1959, as a semi-express service operating between Asahikawa and Abashiri, using KiHa 22 2-car DMUs, with five return workings daily.[2][6] From July 1960, services were extended to Sapporo, and ran coupled with Sōya semi express services over the Hakodate Main Line.[2]

From the start of the revised timetable in October 1961, services were upgraded to "Express" status, and were operated using KiHa 56 4-car DMU formations, including a KiRo 26 Green (first class) car.[2]

From the start of the revised timetable on 2 October 1972, services were upgraded to "Limited express" status, and were operated using KiHa 80 series DMU formations.[2]

From the start of the revised timetable in November 1986, the KiHa 80 series rolling stock was replaced with KiHa 183 series 6-car DMUs.[2]

Sleeper service

From 1992, the former Taisetsu (大雪) express overnight sleeper service was integrated with the Okhotsk (becoming Okhotsk 9 & 10), featuring a SuHaNeFu 14-500 series sleeping car sandwiched in the DMU formation.[7] From March 2006, this became a seasonal-only train (Okhotsk 81 & 82), and the overnight service was discontinued entirely from 16 March 2008.[8]

SL Okhotsk

JR Hokkaido operates seasonal SL Okhotsk services formed of 14 series passenger coaches hauled by a JNR Class C11 steam locomotive and assisted by a JNR Class DE15 diesel locomotive.[9]
