Surveying for the route between Hīhītahi and Piriaka began in 1894.[3] From 1 April 1908 the line from Auckland was extended from National Park to Erua. That reduced the coach journey to the southern railhead at Ohakune to 14 mi (23 km).[4] From 1 May 1908 Erua was supplanted by Makatote as the railhead.[5] On 9 November 1908 NZR took over from the Public Works Department the Taumarunui to Erua line and on 14 February 1909, the line south to Waiouru.[6] Goods trains ran south from Erua from 7 January 1909.[7] Four 5-roomed houses and a 6th class station were built in 1908, with a 23 ft (7.0 m) by 11 ft (3.4 m) shelter shed and urinals on a 200 ft (61 m) by 15 ft (4.6 m) platform, a 20 ft (6.1 m) by 30 ft (9.1 m) goods shed with verandah, a loading bank, cattle and sheep yards and a cart approach. A passing loop could take 49 wagons. Erua was described as a tablet station from 1908. There was a Post Office at the station from 1912 to 1937.[8] Overnight, on 30 May 1921, the station burnt down.[9] It closed to goods traffic, except in wagon lots, on 11 August 1969 and to all traffic on 13 September 1986,[8] prior to electrification. There is now only a single line through the former station site.[10]

Timber
Like the other stations along this part of NIMT, Erua had freight from several timber mills. To supply timber to the Frankton Junction Railway House Factory, a sawmill NZR opened a forestry block. 57 were working in it in 1924,[11] though the number was reduced from 1927[12] and it closed in 1928.[13] To work this block, NZR built a 4.2 km (2.6 mi) siding from Pokaka, which continued to have some use until about 1932.[14] A tablet lock was added to Karioi Sawmill Co.'s siding between Erua and Pokako in 1930.[15] There were several other timber companies at Erua, including Wanganui Sash and Door,[12] whose tramway closed in December 1956.[16] Waikune Prison had a sawmill near the station until 1927.[17]
Marton Sash and Door Tramway
Crighton Bros had a tramway, which ran about 11 km (6.8 mi) west from the station.[16] Some of the tramway became part of a 16 km (9.9 mi) Marton Sash and Door cycleway[18] in 2014.[19] The Marton mill at Erua burnt down in 1939,[20] though it still had a tramway in 1942.[11]
