In the early 1990s, the Ohai line was incorporated into the national network and the line beyond Wairio became known as the Ohai Industrial Line. The motive power used on the line from this stage was the same as that employed to haul the train from Invercargill. Presently, one train runs every weekday from Invercargill and return, arriving at Ohai at 9.30 am and leaving two hours later. This service operates on Saturdays and Sundays when required. In June 2007, the Southland District Council adopted as part of the Otago Regional Land Transport Strategy a provision to upgrade the Ohai line and maintain it as a viable alternative to a road for bulk freight.
