Rolling stock
Kamaishi Line services are operated using KiHa 110 series diesel trains.
From 12 April 2014, a newly formed SL Ginga "Joyful Train" (excursion train) began operating on the line at weekends using the restored JNR Class C58 steam locomotive C58 239 together with a train of four modified former KiHa 141 series diesel cars purchased from JR Hokkaido (themselves rebuilt from earlier 50 series passenger coaches and made surplus to requirements following the electrification of the Sasshō Line). The diesel cars provide additional power to cope with the line's gradients. The coach design work was overseen by industrial designer Ken Okuyama.
Former rolling stock
Following the full opening of the line in 1950, passenger and freight services on the line were hauled by JNR Class D50 2-8-2 steam locomotives, necessary to negotiate the steep gradients on the line of up 25 ‰. A couple of JNR Class 8620 steam locomotives were also used for shunting at Kamaishi Station. JNR Class C58 2-6-2 steam locomotives were also used on both passenger and freight services running to and from the Yamada Line. Six JNR Class D51 2-8-2 steam locomotives were subsequently transferred to the line, displacing some of the earlier D50s, but steam haulage on the line was entirely replaced by diesel haulage from March 1967.
History
The precursor to the line opened in 1915 as the Iwate Light Railway (岩手軽便鉄道), a 762 mm (2 ft 6 in) light railway extending 65.4 km from Hanamaki to Sennintōge Station (仙人峠). The original plan was to link with Kamaishi Mine and Kamaishi Port, but at an altitude of 887m, the mountain pass at Sennintōge prevented immediate expansion eastward to Kamaishi. A ropeway conveyor was used to convey goods onward to Ōhashi, from where a 16km 762mm (2'6") gauge mining railway (which operated between 1915 and 1965) provided the service to Kamaishi.
The railway was nationalized in August 1936, and the line became the "Kamaishi Line". Motive power for the line was provided by six JNR Class 231 steam locomotives, built by Baldwin Locomotive Works in the USA, and numbered 231 to 236. Work started on upgrading and re-gauging the line, and the first section, the 31.2 km from Hanamaki to Kashiwagidaira was regauged to the standard Japanese track gauge of 1,067 mm (3 ft 6 in) and re-opened from September 1943. The mining railway between Rikuchū-Ōhashi and Kamaishi was also upgraded to 1,067 mm gauge by October 1944 to meet the urgent need for increased capacity to transport iron ore during the war period, and was named the Kamaishi East Line (釜石東線, Kamaishi-Higashi-sen). The entire 90.2 km line was finally completed between Hanamaki and Kamaishi in June 1950, opening to traffic on 10 October of that year.
