1880, March: Opens as one of the original stations on the North Auckland Line.
1983, March: The Auckland Regional Authority decides to relocate the station east, to the other side of the Rankin Avenue-Totara Avenue-Clark Street road intersection and adjacent to the bus station, despite the uncertain future of Auckland suburban services.
1987, August: The old station building is demolished after vandals broke in and damaged it.
2006, December: Double-tracking between New Lynn and Avondale is approved by the central government; the $120 million package includes a 1 km long, 8m deep trench to carry the tracks, and a new station with below-ground platforms. Trenching the tracks means that they will no longer pass directly through the Rankin Avenue-Totara Avenue-Clark Street road intersection, removing a source of traffic congestion and the potential for collisions.
2008, March: The station platform is demolished and a temporary platform constructed to make way for the rail trench earthworks.
2010, 1 March: Trains begin running in the trench on a single track.
2010, 29 April: The first steam train runs in the trench, Ja 1275 on the Northlander to Whangarei.
2010, 8 June: Trains begin running through the trench on two tracks, completing the Western Line Double Tracking Project.
2012, April–June: The station shelters are transformed and a glass encased stairwell shelter is put into place due to high patronage use.
Rail trench
In the late 2000s, local and regional government, as part of the revitalising of the regional rail commuter network, decided to build a new "feature station" at New Lynn, which included sinking the tracks and station into a trench. Road was grade-separated from rail to enable vehicle traffic to pass over the line. Before the trenching works, the level crossings in the town centre were often blocked by passing trains, leading to substantial road congestion, which would have only increased with more train services. The new rail trench and associated sunken station were to be constructed with up to 16m deep diaphragm walls using specially imported cranes and specialists. This was required due to the unstable, water-logged soils and the need to avoid settlement damage to close by buildings. The procedure to construct the 1 km of trench involved multiple temporary shifts of the railway line and of various associated roads, and was called the most difficult part of the DART railway development programme in Auckland. Wet ground conditions had also forced a redesign of the trench methods, and delayed the project start by six months.
