1935 - 1975|
A middle to large Tender-Engine for main and sub-main line freight trains.
D51 No. 62
At Rumoi dept during Mar.1970.
It may be said that the D51 was the first completed Japanese modern steam locomotive class.|
If one were to ask, " What is the most popular steam locomotive in Japan ? " ... the answer would be the D51. D51 has a nickname " Degoichi ". In English, of course D is pronounced D and "go" is five and "ichi" is one. It's not only rail-fans but regular Japanese also, that have a knowledge of this nickname.
D50's manufacturing ceased during 1931 due to an economic downturn. Afterward, there was no new freight model design for awhile. During 1936, there was an increased need for a new freight model, as increased freight meeds were dictated because of the wartime structure.
D51 was planned with this background in mind, so, D51 had almost the same specifications as the class D50. D51's performance was matched for Japan's main and sub-main line tracks, and was very appreciated all over Japan. Therefore, a total of 1,115 (*) No.1 - 954 and No.1001 - 1161 were built. It was the largest single class locomotive manufactured in Japan.
(* JGR - 1115, Taiwan R. - 37, Exported Soviet Union - 30, Total - 1,182)
The D51 was largely produced and accordingly had some variation.
After its inception, the D51 went into main line freight train service, and worked with D50s. And that service area was extended to almost all Japanese railways, except for electrification and poor grade local lines.
During 1941-1943, Iburi Jyukan Railway Co. ordered five D51s as Iburi Railway No.D5101-D5105. During July 1944 Iburi Jyukan Railway Co. was nationalized and they were transferred with the ensuing JGR D51's No. 950 - 954.
During 1944, five D51s were ordered from Taiwan Railway as a Taiwan Railway's Class D51 No.28 - 32, but they couldn't be transferred to Taiwan as the war became worse . Therefore, they were renumbered with the ensuing JGR D51's No. 1162 - 1166, and were used in JGR. Later they were transferred to Taiwan after the war end during 1946.
After WW2, thirty-three engines were reconstructed to passenger models C61 from their surplus condition. As with previous D50 to D60's, six engines were altered with a relieved axle load (2-8-2 to 2-8-4), for the purpose of testing and using on more light grade lines. They were named D61.
D51's continued to be active during the post-war period except on Shikoku Island. Yet, 1,042 engines were still active even during 1965, except for those that were remodeled and sent out from the Japanese mainland and those that were discarded due to accidents etc.
Surplus full culling began from 1966. There were 1,042 of D51s during 1965, 5 years later, during 1970, the number was decreased to 756, and was decreased to 342 during 1973, and decreased by 78 during early 1975. However, six D51s survived until the end of steam trains during December 1975. They were Oiwake depot's No. 241, 397, 465, 603, 916 and 1086.

The restored D51-498 remains active on JR East during spring, summer and fall.
