The station is located on the Hutt Valley section of the Wairarapa Line, 31.3 km (19.4 mi) north of Wellington, and is served by Metlink on behalf of the Greater Wellington Regional Council.

The Blue Mountains Campus at Wallaceville is to be the location for KiwiRail's national Train Control Centre, which is to move from the Wellington railway station; to house a team of 120 train control team members in a 2700 square metres train control room.

[5] The station was opened and closed in the 19th century; Scoble refers to a Whiteman's Valley platform c1879.

[8] The section between Upper Hutt to Trentham was single track, but as part of the 2020-2021 Wellington Metro Rail Upgrade (and as proposed in the 2011 – 2012 Regional Rail Plan (RRP)) the section was double-tracked by 2021.

The original platform is used by up or northbound trains and the new platform built to the east for down or southbound trains, with a building similar to the Ava station building.
