Otahuhu Workshops

From Wikipedia, the free encyclopedia

Coordinates: 36°57′9.06″S 174°49′44″E / -36.9525167, 174.82889 The Otahuhu railway workshops were a major rolling stock maintenance and repair facility of the New Zealand Government Railways Department, located 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 in the 1990s.

The 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 Hutt 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 heavy machinery required for locomotive work.

But though officially a Car and Wagon Shop, Otahuhu also did some repair and maintenance work on, first steam, then diesel, locomotives as well as railcars. Some of Wellington’s fleet of D class electric multiple unit carriages were also overhauled there.

[edit] History

The 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 were closed.

Though the buildings for the new facility were all located on the same site, there was a Midway that separated two groups of buildings. On the western side of the yard was located the Wagon Shops, Machine Shop, Blacksmiths Shop, Reclaim, Powerhouse and Stores. To the east were the Structural Shop, Trimming Shop, Car Shops No. 1 and 2, and the Woodmill. During the life of the workshops, increasing demands for rolling stock and new requirements necessitated the extension or modification of the Structural Shop and the Machine Shop, and the installation of an Electroplating Shop and Battery Shop in the Trimming Shop. Other buildings included an administration block, schoolroom and canteen.

The workshops played their part in the war effort. Prior to New Zealands involvement in World War II, there was a building on site that was known as the Air Force building. It was intended to be used to train apprentices in aircraft maintenance, but the situation changed resulting in the Air Force occupying the building for the duration of the war. The war also saw many workshop staff seconded outside the workshops, to places such as the Devonport Naval Base and several local engineering firms that were contracted to the military for the production of war supplies and equipment. Some of the work undertaken by the workshops during the war included the production of slat beds for the Army, small-arms ammunition machines for the Colonial Ammunition Company, dual flying yokes for Airforce craft, and tugboat hulls for the Americans. One special job was the conversion of six 56ft second-class carriages into ambulance cars, intended to be used for the transport of wounded soldiers arrived home from the war.

A programme for the construction of 60-foot carriages intended for Main Trunk service prompted the construction of a new workshop building about 1940, known as Car No. 1 Extension. Though the programme was eventually cancelled, even after much of the material needed for their construction had already been imported, the infrastructure still proved to be useful in the 1950s when the D-class electric coaches from Wellington were overhauled there.

Other new buildings at the site included a Diesel Shop in 1962, and a new Woodmill to replace the old Woodmill that was destroyed in a major fire on 31 May 1955. The machines that were installed in the replacement Woodmill were more modern than those available in the old building, resulting in much improved output.

Though officially designated a Car and Wagon Workshop, Otahuhu did occasionally handle other work. This 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.

Production of carriage stock began soon after opening in 1929, the first of which were 10 50ft “Aa” suburban carriages. Later, another batch of 50ft cars was completed for use on the new Rotorua Limited Express service, including two observation cars. A large number of the 50ft cars were built at Otahuhu prior to the introduction of the 56ft carriage variety, which were manufactured between 1937 and 1945. In all, Otahuhu was responsible for producing 207 carriages, 75 guards vans, 3 steam vans, 3 postal vans, and an almost innumerable number of wagons.

With the onset of the diesel age, Otahuhu became involved in the maintenance of diesel locomotives. This started with the small TR tractors in the early 1940s, with the work being carried out in Car Shop No. 2. As the use of diesel motive power became more prevalent, it was necessary to provide dedicated facilities for working on these vehicles, with the Steel Wagon Shop being converted for this purpose. In 1958, Otahuhu received the first of its Fiat twin-set railcars for an overhaul, and in 1962 RM 125 was repaired at the workshops following a level crossing accident in Tauranga.

Other diesel work conducted at the Steel Shop included the readiness for service of 12 “Da” class locomotives in 1961, and the restoration of DA 1405 following a major accident. Minor repair work on DE class locomotives was done by the Machine Fitting Group.

The ability of Otahuhu to handle diesel-electric locomotive and railcar repair work was much improved in 1962 with the opening of a new Diesel Shop. Prior to entering service, many DA, DB, DH, and DX class locomotives first made a visit to Otahuhu to prepare them for their new duties. Fiat railcars were also maintained, repaired and overhauled in this new facility. In 1971, the recently imported Silver Star carriages were tested and commissioned in the Diesel Shop, as were the Silver Fern railcars the following year in 1972. Several cars for the new Southerner service were overhauled at Otahuhu in 1970.

In its later years, Otahuhu carried produced more specialist wagons, including those designed to carry containers and coal, as well as many other variants.

[edit] Demise

By the 1990s, the Railways Corporation (successor to the old Railways Department) was experiencing severe financial hardship. In an effort to alleviate its problems, and at the direction of its then political masters, the Railways underwent a restructuring which included a review of all its workshop facilities around the country. It was decided to focus the rail engineering resources at two sites; one in the North Island at Hutt Workshops, and the other in the South Island at Hillside Engineering in Dunedin. This resulted in the closure of both the Addington and Otahuhu workshop facilities.

By written notification, all employees of the Otahuhu Workshops were informed that the workshops were to formally close on 30 June 1992. A small team of up to 22 employees was kept on for a further six months in order to fully decommission the facility. Machines that could be sold were stored in the Structural Shop pending sale by auction. At the time, the workshops site was believed to be destined to become an industrial park.

[edit] Today

Over half of the original workshops buildings have been demolished since the facility closed. Part of the site is now used as a container storage yard.
