Ōtāhuhu railway station is located on the Eastern and Southern Lines of the Auckland rail network in New Zealand.

It can be reached by steps and lift from an overhead concourse that leads from the adjacent bus transfer station and Walmsley Road.

Ōtāhuhu station features a historic, decommissioned signal box and is the point where both freight and passenger trains enter and exit the main line from the Westfield locomotive depot.

Mainline signalling in the Ōtāhuhu station limits will be operated from the National Train Control Centre (NTCC) in Wellington, along with the rest of the Auckland network.

A new southbound platform, 1.3 km (0.81 mi) of track and four crossovers were opened in December 2020, as part of the City Rail Link works to enable trains to turn back and reduce the need for bus passengers to use the bridge.
