Waterloo railway station, Lower Hutt
Waterloo railway station (previously known as Waterloo Interchange or Hutt Central) is a dual-platform suburban railway station located in Lower Hutt, New Zealand, and serving immediately the suburbs of Waterloo, Lower Hutt Central and Woburn. The station stands on the Hutt Valley section of the Wairarapa Line,  north of Wellington. Trains stopping at Waterloo run to Wellington, Taita, Upper Hutt and Masterton, as well as to points in between. Waterloo serves as a major bus-rail interchange, connecting buses to and from central Lower Hutt, Naenae and Wainuiomata with trains to and from Wellington. History 

Two major reasons were the impetus for the construction of the Hutt Valley Branch between Petone and Waterloo: first, the Petone Workshops had reached the end of their useful life; second, with increasing traffic demands on the line between Petone and Haywards and the lack of room to double-track the line on its existing route meant a new mainline had to be built. The line was surveyed between 1924 and 1925, with a short industrial branch leaving the Hutt Valley Branch at Woburn to serve the new Hutt Workshops. On 26 May 1927, the rails reached Waterloo, which was then in the middle of open fields. This station was the terminus of the Hutt Valley Branch line until an extension north to Naenae was opened in 1946. The station was opened with automatic, three-aspect colour light signals which had been standard since 1924. As the station provided a direct rail connection to the port at Wellington and the surrounding land was flat, it was during the latter part of World War II that land near the station was occupied by a number of storage facilities, among them one for the United States Joint Purchasing Board. In 1944, work began on extending the Hutt Line north to Naenae, which as the line was being twin tracked required the construction of a new station. This opened in 1948 and incorporated pedestrian subways on both sides. It was always intended that Waterloo would one day serve a major population centre which, in the years following World War II and the population boom that ensued, was proved correct. Significant urban development of the Hutt Valley in the 1940s led to the decision in February 1946 to commence electrification in 1949 and to operate electric train between Waterloo and Wellington from August 1953. Until the connection of the Hutt Valley Branch to the Wairarapa Line and its opening as the new mainline on 1 March 1954, Waterloo served only suburban passenger services, with Upper Hutt and Wairarapa trains continuing to use the old line between Haywards and Petone on the western side of the Hutt Valley. In 1986, as a result of the Hutt Valley Transport Study, Waterloo was designated an interchange for bus and rail services in preference to Woburn, which had previously had this role. It was felt that Waterloo was a more logical choice as it was closer to centres of residential and commercial interest, had sufficient room for bus platforms to be installed, and was not burdened with other operational requirements such as Woburn being the junction with the Gracefield Branch, with its loops and sidings. In December 1987, the existing station was demolished and construction commenced on a new interchange facility at Waterloo which was opened on 26 November 1988. It was fully integrated with all the new public transport routes and timetables by the following March. The new building incorporated offices for Railways Road Services (NZRRS) and on the southwest side a bus park and workshop for their fleet. However the NZRRS was soon separated from the railways management structure and as they relocated to another site the offices became empty. Despite being 1.4 km from the central business district, the station was also called Hutt Central for a period. On 29 June 2021, the Greater Wellington Regional Council announced plans for a new transport interchange to replace the existing station at a projected cost of $20.25 million. Services
