NZR DG Class
The New Zealand DG and DH class locomotive were a type of diesel-electric locomotives in operation on New Zealand's rail network from 1955-1983, built by English Electric. Introduction Due a change in NZR's dieselisation strategy the original order for 21 DF class locomotives was changed to 42 DG class locomotives, being a half-sized version of the DF with only one cab instead of two, and a similar Bulldog nose. English Electric, as they did with many of their diesel locomotives of the 1950s-60s, did not assemble them at the Preston works, but allocated the final assembly of build numbers 2254/E7821-2273/E7840 (NZR road numbers 750-769) to Robert Stephenson & Hawthorns and build numbers 2274/D353-2295/D374 (NZR road numbers 770-791) to Vulcan Foundry, both English Electric plants. The South Island allocated locomotives were initially classified DH because they were fitted with adjustable bogies that allowed a higher maximum axle weight and tractive effort The DG and DH axle lo ...

English Electric
N.º UIC: 9094 110 1449-3 (Takargo Rail) The English Electric Company Limited (EE) was a British industrial manufacturer formed after the Armistice of 11 November 1918, armistice of World War I by amalgamating five businesses which, during the war, had been making munitions, armaments and aeroplanes. It initially specialised in industrial electric motors and transformers, railway locomotives and traction equipment, diesel motors and steam turbines. Its activities were later expanded to include consumer electronics, nuclear reactors, guided missiles, military aircraft and mainframe computers. Two English Electric aircraft designs became landmarks in British aeronautical engineering; the Canberra and the Lightning. In 1960, English Electric Aircraft (40%) merged with Vickers (40%) and Bristol (20%) to form British Aircraft Corporation. In 1968 English Electric's operations were merged with GEC's, the combined business employing more than 250,000 people. Foundation Aiming ...

New Zealand DH Class Locomotive
The New Zealand DH class locomotive is a type of diesel-electric heavy transfer and shunting locomotive in New Zealand's national railway network. The class consists of six heavy shunt U10B type locomotives built by General Electric United States at their Erie, Pennsylvania plant in 1978. Five of the class are used in the Auckland area for heavy shunting duties, including services around Auckland and the Port of Auckland, while one is based at the Port of Tauranga in Mount Maunganui. Introduction Originally an order for Philippine National Railways 2500 Class, the six locomotives were purchased as by coincidence NZR needed a heavy shunter for Auckland container port transfer work. At the time two DSC class shunters were linked in tandem to perform this task. The DH class are a light locomotive which are geared to run at . They saw occasional service on the then under-used Auckland suburban passenger network where they performed well, but NZR focused them on their intende ...

Weka Pass Railway
The Weka Pass Railway is a New Zealand heritage railway based in Waipara, North Canterbury. It is operated on a 12.8 km length of the former Waiau Branch railway between Waipara and Waikari. The railway is operated by an incorporated society whose members come from all walks of life and are largely resident in the city of Christchurch, 60 km to the south. The railway began carrying passengers in 1984 and is now well established locally and nationally. History Beginnings The first stage of the Waiau Branch line inland through the Weka Pass to Waikari was completed in 1882. This area is noted for its scenery and the railway passes through many large cuttings, around tight curves and on steep gradients (max 1 in 47). When originally built the line was expected to be part of the South Island Main Trunk Railway north of the city of Christchurch. Further sections of the line through Hawarden, Medbury, Balmoral, Pahau, Culverden, Achray, Rotherham and Waiau were construc ...

Midland Line, New Zealand
The Midland line is a 212 km section of railway between Rolleston and Greymouth in the South Island of New Zealand. The line features five major bridges, five viaducts and 17 tunnels, the longest of which is the Otira tunnel. It is the route of the popular TranzAlpine passenger train. History Railway development in the South Island in the 1870s was concentrated on a main line linking the established centres of Christchurch, Timaru, Dunedin and Invercargill and light, easily constructed branch lines serving the arable plains; (see Vogel Era). These later included a branch to Springfield which was reached by January 1880. In 1882 the East and West Coast Railway League was formed and in 1884 a Royal Commission, although fully aware of the construction difficulties of the Waimakariri Valley-Arthurs Pass route, as compared with the somewhat easier but longer Hurunui Valley-Harpers Pass route, chose the more direct route. The construction of the line was rejected in 1883 ...

Metalock
Metal stitching is an industrial technique for repairing cracked and broken cast iron, steel, bronze or aluminium structures and their components. The process is carried out cold, without welding. It allows the repair of cast iron and cast steel, often in-situ, without the distortion from welding, and can be used in other situations where heat cannot be used to achieve a repair. Background The metal stitching process was developed in the late 1930s as an option for repairing cast iron components and equipment on the Texas oil fields. The process was developed to provide a permanent, stress-free repair and utilized when the use of heat or open flame was limited or not allowed. Four men have been credited with the development of this new metal locking technique: Lawrence B. Scott, Fred Lewis, Earl Reynolds and Hal W. Harman. However, it was Hal Harman who initially invented the metal stitching technique, and he filed for a patent to the technique in the 7th of August, 1937. In 1938 ...

New Zealand DX Class Locomotive
The New Zealand DX class locomotive is a type of 49 Co-Co diesel-electric locomotives that currently operate on New Zealand's national railway network. All locomotives are owned by KiwiRail. Built by GE Transportation in Erie, Pennsylvania, United States, they were introduced to New Zealand between 1972 and 1976. The class is based on the General Electric U26C model, a narrow-gauge version of the GE U23C model. The locomotives are regarded as one of the most successful purchases in NZR's history. The locomotives have seen several upgrades since their introduction and three sub-classes now exist: the DXB, DXC and DXR. Introduction The DX class was introduced in response to a requirement for a more powerful locomotive to handle traffic on the North Island Main Trunk (NIMT). Before their introduction the heaviest freight and passenger trains on the line required two members of the DA class to haul them. The DX class could haul heavier and faster trains than two DAs, even tho ...
