[1] The train consisted of restored JNR Class C58 steam locomotive number C58 239 together with four rebuilt 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 in 2012).

[2] The overall concept was inspired by the classic novel Night on the Galactic Railroad written by Japanese author Kenji Miyazawa, who lived in Hanamaki, Iwate.

[1] The dedicated SL Ginga train locomotive C58 239 was built in June 1940 by Kawasaki Sharyo, and was based at various depots around the country, including Nagoya, Nara, and Morioka, before being withdrawn on 22 May 1972.

[8] It was announced in 2021 that the service would be withdrawn in spring 2023 due to the increasing age and deterioration of the KiHa 141 passenger cars.

[9][10] The train made its final run on 11 June 2023 to throngs of railway enthusiasts and locals bidding it farewell.
