Operation

The Walton Park Branch's operations were of little significance. 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. This event in itself was so unremarkable that the railways annual report failed to mention it. After this stage, the branch was shunted only when required, and did not even appear on the public timetable by 1950. 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

The branch today

Very little remains of the Walton Park Branch. In 2000 the Southern Motorway extension was built over the formation to Saddle Hill. 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
