Yard shunter built by Mitsubishi in 1967.
ORB No 2 was one of two locos built by Mitsubishi Heavy Industries for the Ohai Railway Board in 1967. They were primarily used for hauling coal trains betwween Ohai and Wairio on their private line. ORB No 2 was withdrawn in 1990 after New Zealand Railways took over the Ohai Railway Boards section of the Wairio Branch line.
In 1992 it was purchased by long time Steam Incorporated member, the late Reid McNaught for use by Steam Inc as a depot shunter at our Paekakariki site. It was later sold to another Steam Inc member and is still in regular use for shunting duties at Paekakariki.
Sister engine ORB No 1 is now stored at the Ocean Beach Raillway in Dunedin.
