Sanuki 0-4-0 Locomotives in Japan


Class Details by Steve Llanso of Sweat House Media

Class A1/29/60 (Locobase 10959)

Data from [link]; and "JGR Class 60" in Locomotive Wiki at [link], last accessed 12 January 2024. Works numbers were 483-484 in 1888, 490 in 1889, 765 in 1894, and 1479-1482 in 1901.

Hamburg locomotive broker C Illes bought all eight of this class of light shunting tank engines for the Sanuki Railway. Some time later, the Sanyo Railway took over the Sanuki and redesignated the A1s as Class 29.The Railway Modernization Act nationalized much of the system, which developed a single classification scheme that placed Class 29s in Class 60.

By 1923, the JGR removed the Class 60s from the roster and made them available to several industrial sites. After another 40 years of such service, the class was disposed of in 1964.
