Until the original Martha gold mine in Waihi closed in the early 1950s the ore was transported by rail to Victoria Battery at Waikino in the Karangahake Gorge. This rail line ran alongside the left bank (southern side) of the Ohinemuri River. Part of the Hauraki Rail Trail now follows the route taken by this railway line. On the right bank of Ohinemuri River the New Zealand Rail railway line between Waihi and Paeroa followed alongside State Highway 2. The railway line was closed when the Kaimai Rail Tunnel was completed, but the line between Waihi and Waikino is now used by the Goldfields Historic Railway to carry passengers on the 30-minute journey between the two end points.
Goldfields Railway will also transport bicycles, so it is possible to take the train in one direction, and then walk or cycle in the other direction. Here the rail journey was taken from Waihi to Waikino and the walk done on the Hauraki Rail Trail cycleway/walkway from Waikino back to Waihi.
