The NZR KB class of 1939 was a class of mixed traffic steam locomotives that operated on New Zealand’s railway network. They were built by the New Zealand Railways Department (NZR) after the success of the K class to meet the increasing traffic demands on the Midland Line in the South Island. The locomotives had a wheel arrangement of 4-8-4 and first appeared with distinctive streamlining mainly to hide their ACFI feedwater systems.
