The Walton Park Branch was located in Otago, New Zealand and operated from 1874 until 1957, except for the first section, which survived until 1980.
The only structure associated with the branch built along its entire length was a shelter shed at Walton Park.
A review in 1895 said the line was in good order, and nothing of any note occurred until the section from Walton Park to Saddle Hill closed on 24 July 1944.
Coal traffic ceased seven years later and official closure occurred on 1 May 1957, though the first 0.58 km to Geddes was retained and used as a spur until 1 January 1980, and had necessitated the construction of an expensive underpass tunnel when the long drawn out construction of the Dunedin Southern Motorway began in the 1970s.
Commercial and residential development has obliterated the rest of the old formation, though some is still visible from State Highway 1, a significant relic being the motorway underpass tunnel at Green Island.
