Otahuhu Workshops
Coordinates: 36°57′9.06″S 174°49′44″E / 36.9525167°S 174.82889°E Otahuhu Railway Workshops were a major rolling stock construction, maintenance and repair facility operated by New Zealand Railways, in the south Auckland suburb of Otahuhu in New Zealand's North Island. The workshops were opened in 1928, and were closed in 1992 as part of a rationalisation of workshop facilities throughout the country.
Otahuhu Workshops were built following a report that highlighted the inadequacies of the Newmarket Workshops, the central Auckland facility that the Otahuhu Workshops replaced. Originally it was proposed that Otahuhu would carry out locomotive work and Wellington's Hutt Workshops would be the Car and Wagon Workshop. This was reversed when it was found that the land on which Otahuhu was to be built was not suitable for the heavy machinery required for locomotive work.
Though officially a Car and Wagon Shop, Otahuhu did some repair and maintenance work on steam and diesel locomotives and railcars. Some of Wellington's fleet of D class electric multiple unit carriages were overhauled there. Other work included light maintenance on steam locomotives, with particularly busy periods being 1929–1930 when 37 locomotives received overhauls and boiler repairs, and 1947–1949 when Otahuhu was called on for the urgent conversion of 19 K and Ka class locomotives to oil burning. Some other years in which locomotive work was carried out were 1931, 1933, 1942, 1945 and 1946.
The New Zealand Railways Department called for tenders for "new Car and Wagon Shops at Otahuhu near Auckland" on 30 September 1926 following the Fay-Raven report of 1925. By 1928, the new facility was completed, and some men from the Newmarket Workshops were tasked with installing new equipment at the site. The workshops officially opened for business following the Christmas holiday period of 1928–1929, at which time the Newmarket Workshops closed.
