Upper Hutt railway station is a suburban railway station serving central Upper Hutt, New Zealand. The station is on the Wairarapa Line, 32.4 km (20.1 mi) north of Wellington, and is served by Transdev Wellington on behalf of the Greater Wellington Regional Council. The station is the northern terminus for the electrified Hutt Valley Line to and from Wellington. The diesel-hauled Wairarapa Connection stops at Upper Hutt on its route between Wellington and Masterton.

The station opened with the line from Wellington in February 1876, and was substantially rebuilt in 1955 with electrification to Upper Hutt. In 2015, the station was upgraded with a new station building and refurbished platforms. The station has two platforms, a side platform on the main line and a bay platform on a spur off the main line. Overnight storage of electric multiple units is provided in fenced sidings adjacent to the station.

As part of the 2020-2021 Wellington Metro Rail Upgrade with double tracking of the single track section from Trentham to Upper Hutt (as proposed in the 2011 – 2012 Regional Rail Plan (RRP) and completed in November 2011 handling of two trains at the same time will be improved by adding two new crossovers from the main platform to the inner loop track (there is also a second or outer loop track). The inner loop track will be extended to the north with a new north end crossover to it so that long Wairarapa log trains can be ”parked” out of the way of passenger trains.

Construction of the Wairarapa Line to Upper Hutt was covered by the River Contract, which was let to contractor Charles McKirdy. The rails reached Upper Hutt in January 1876. Severe flooding at the end of January caused the road between Upper Hutt and Taita to become blocked and damaged, and so to minimise the impact caused by delays to road traffic, the Upper Hutt station was opened on 1 February, despite the concerns of the Public Works Department that the move was premature. The station was not ready for business, as the station and ancillary buildings had not been completed. However, the line and station were handed over to the Provincial Council to run while construction of the line beyond Upper Hutt commenced.

With the line open as far as Upper Hutt, traffic began to increase. Goods traffic initially consisted mostly of timber, followed closely by wool. Passenger services consisted of three weekday return services to Wellington. One effect of the introduction of services between Wellington and Upper Hutt was the reduction in road coach services, which, from the north, terminated at Upper Hutt. Goods wagons, however, continued on to Wellington. Still, railway traffic benefited by a 50% increase due to the establishment of the railhead at Upper Hutt.

The year the station opened, it gained a fourth-class station building, goods shed, coal store, an engine shed and two water tanks for the sum of £2,040. In 1955, as part of the station upgrading programme for the imminent arrival of electric multiple unit working of the Hutt Valley Line, a new station building was erected at Upper Hutt.

While trains only operated as far north as Upper Hutt, they were not protected by fixed signals. It was felt that as services were few, slow, and operated only in daylight hours, signals were not necessary. Upper Hutt was one of the first stations on the Wairarapa Line to receive signals, with initial instructions requiring south-bound trains to wait in the siding or loop, and north-bound trains to take the main line. These signals were first listed in the working timetables of 1887. By 1921, increased traffic was causing operational issues, and it was decided to install new automatic signalling which had been recently developed in the United States. Work began in 1921, and by early 1923 was operating between Wellington and Upper Hutt.

In 1955, with the opening of the Rimutaka Tunnel and deviation, a Centralised Traffic Control system was installed at Upper Hutt station to control main line points and signals between Trentham and Featherston inclusive. However, only one crossover (18) and four signals (8, 23, 23A and 29) at Trentham could be controlled from Upper Hutt; the remainder, which were typically only used on race days at the adjacent Trentham Racecourse, were controlled by a panel at Trentham itself. The semaphore signals were replaced with three-colour searchlight signals. On 6 February 2007, the Upper Hutt signal box was decommissioned and control of the line from Trentham to Featherston was moved to Train Control in central Wellington.
