No. 39 of the San'yō Railway was a single 2-4-2 passenger locomotive built by Baldwin in 1895. The manufacturer designated it type 8-14/28 1/4C and it originally carried a name plate “K. Minami” after the chief engineer of the railway. It was a four-cylinder Vauclain compound with high pressure cylinders above the low pressure cylinders. The leading axle was mounted in a flexible Bissel truck, while the trailing one only had some lateral play. After the railway was nationalized in 1906, the new scheme of 1909 made the single locomotive class 5060. In later years it was used in freight service and its withdrawal came in 1919.
