Ōmiya Works

Ōmiya Works (Japanese: 浜松工場 Ōmiya Kōjō) is a rolling stock maintenance facility under the jurisdiction of the East Japan Railway Company (JR East). Currently a part of the Ōmiya General Rolling Stock Center (Japanese:大宮総合車両センター Ōmiya Sōgō Sharyō Sentā), Ōmiya Works specializes in major maintenance of JR East's rolling stock and was formerly a manufacturer of rolling stock.

History[]

Ōmiya Works was opened on 15 December 1894 by the Nippon Railway, initially as a temporary base of operations; it was later redesignated as a full factory on 1 September 1896. Ōmiya Works assembled its first steam locomotive, No. 3 (later 5270), in October 1901; although considered the first locomotive built by Ōmiya No. 3 was actually built from a set of spare parts from the Class Dbt2/4 locomotives manufactured by Dübs & Co.; after this, Ōmiya would also manufacture six Class O3/3 (later Class 1040) steam locomotives as a copy of the Nasmyth-manufactured Class W3/3 locomotives. Ownership of Ōmiya Works was transferred to the Japanese Government Railways (JGR) when the Nippon Railway was nationalized on 1 December 1906. Ōmiya also manufactured the Class 10020 electric locomotives (later Class ED40) from 1919 to 1923, the first domestically-produced electric locomotives in Japan, manufacturing both the electrical and mechanical components of the locomotives.

Ōmiya would complete its first steam locomotive, D51 187, on 9 September 1938; a total of 30 steam locomotives, all Class D51s, were manufactured by Ōmiya, with the last steam locomotive being manufactured by Ōmiya being D51 517 on 11 March 1942. Ownership of Ōmiya came under the Japanese National Railways (JNR) following JGR's reorganization post-war. The last steam locomotive to be repaired at Ōmiya was D51 507 on 9 October 1968; most steam locomotive maintenance was transferred to Kōriyama Works the next month. Following the privatization of the JNR, Ōmiya Works came under the ownership of the JR East.

Today, Ōmiya Works remains a major repair and maintenance facility for many of JR East's trains; it can be seen from the New Shuttle as it departs from Ōmiya Station. Some steam locomotive repair functions are also conducted at Ōmiya.
