RSR 60cm gauge Koyosan Kogyo (Japan) 0-4-0T no. 31 (probably) (works no. 6070 of 1949) at Makkasan Works. The loco came from a feeder line, part of the RSR network, between Hua Wai and Sun Noen on the northeastern line, about 30kms west of Nakorn Rajasima, which closed in 1965. One of three similar engines built for the line in 1949.
