Located roughly halfway between
Timaru and
Oamaru,
Waimate is the major market and service town for the surrounding district, but when the Main South Line between
Christchurch and
Dunedin was constructed, it was built some to the east of the township so that it could follow a direct route along the coastal plain without deviating. Both government and residents agreed that a link from the main line village of
Studholme to Waimate was necessary. In 1876, tenders were called for the line and the winning offer, George Pratt's of £4,831, was accepted on 10 March 1876. Construction was not difficult and the branch opened on 19 March 1877. The first train was hauled by an
A class tank locomotive and had three carriages plus a guard's van. Two proposals for an extension were made, of which only one eventuated. The plan which did not eventuate was to link Waimate to either
Duntroon or
Livingstone. One of the proposals for the
Otago Central Railway was to build a line from
Oamaru to
Naseby, and in 1877 an invitation was extended to the Waimate County Council to partake in a plan to connect Waimate to the Oamaru-Naseby line in either Duntroon or Livingstone and thus establish a through route from
Central Otago to
Canterbury. A deputation representing the advocates of the Oamaru-Naseby line made a presentation before the Waimate County Council on 12 July 1877, but the Council did not view the proposal as desirable. The Oamaru-Naseby proposal itself failed to come to fruition, with Duntroon ultimately served by the
Kurow Branch and Livingstone located near the terminus of the
Tokarahi Branch. The other extension proposal was for a line into the hinterland behind Waimate, and this one was successful. Local residents established the Waimate Railway Company in late 1878 to construct an extension from Waimate to the
Waihao Valley, and work commenced after W. J. Black's tender for construction of the first section was accepted on 16 April 1882. The initial were built quickly, with the line opened to Waihao Forks on 2 February 1883. Another of trackage to Waihao Downs followed, and this was opened on 24 April 1883, with a small locomotive depot established at the Waihao Downs station. On 1 April 1885, in accordance with the terms of the 1878 District Railways Act under which the Waimate Gorge Branch had been built, the government agreed to take control of the line. There was local pressure to extend the line further and some
formation was constructed in 1914 with the goal of continuing the railway to
Waihaorunga.
World War I brought construction to a halt as resources were diverted elsewhere and work did not resume after the war ended. By 1924, the government had decided that extending rural branch lines was not profitable and thus permanently put an end to any plans to build beyond Waihao Downs. == Stations ==
