Notable locomotives was the last remaining Australian Standard Garratt and the narrow gauge Clyde-GM G-8 numbered D1. It was the first locomotive to be moved to Dinas, in January 1997. NG51 was put on trials on the Avontuur line in May 1920. Although the simple-expansion concept diverged from Mallet's original patent, the locomotives were clearly a continuation of the concept and were still referred to as "Mallet" locomotives. [1][2], The success of the Class NG G13 narrow gauge Garratts that were introduced by the South African Railways (SAR) in 1927 led to a decision that any additional narrow gauge articulated locomotives would be of the same design. Some parts including the British built Hunslet boiler used to make 116 whole. In 2017, at least four establishments still operated or were restoring ex-SAR Class NG G16 Garratts. Similar to 2100, built at Boston Lodge. 3985 is being restored to operating condition by the Railroading Heritage of Midwest America.[12][13]. NG51 was later returned to the Avontuur line to replace the retiring Class NG3 no. Funded by the WHR Society. In 2004 the locomotive was purchased by a member of the Lynton & Barnstaple Trust, who shipped it from Australia in 2005. Independent cut-offs for the high-pressure and low-pressure cylinders were advocated by Mallet, but driving standards were inadequate and he later used combined cut-off control. [1], When the four narrow gauge branchline systems in Natal were closed down by the SAR, the Weenen and Mid-Illovo lines were torn up. 156 power units were cut up at Paddock in October 2017. Also common for many locomotives is a livery of horizontal bands of green, brown, and a yellow stripe. [4], A powerful steam locomotive is problematic on a track gauge of only 2 feet (610 millimetres) with a tight minimum radius of about 150 feet (46 metres) which, in practice, restricts powerful rigid-frame locomotives to four-coupled wheels, often with at least one flangeless coupled wheelset. This page was last edited on 4 August 2022, at 12:33. Purchased in summer 2009 for use on works trains from a private buyer. Built by Societe Franco-Belge builders No.2974, Beyer Peacock builders No.7623. NG140, is used as a source of spare parts while four locomotives, Cockerill-built no. On cabside number plates, the spelling of the Afrikaans inscription was later altered with "AFRIKANSE" changed to "AFRIKAANSE" and with "SUID AFRIKAANSE SPOORWE" unhyphenated, and stil later to "SUID-AFRIKAANSE SPOORWE" hyphenated. These locomotives were introduced in 1926 to increase train sizes and thus reduce losses on . These three locomotives were not superheated. This 180hp Gardner 6LXB diesel-engined locomotive was built for R.N. Garratts may not be nearly as big as Big Boys, Yellowstones, Alleghenys, etc. One class P1 locomotive was at Viharamahadevi (Victoria) Amusement Park[14], S1S8 Diesel Hydraulic Multiple Units, S9S14, S14A Diesel Electric & Electro-Diesel Multiple Units. A number of the Union Pacific "Big Boys", are preserved, including one overlooking Omaha, Nebraska where UP is based. Sixteen "Beyer-Garratt" locomotives of the 4-8-0 + 0-8-4 type are in service on the 5 ft. 6 in. Diesel locomotives and multiple unit numbering started from 500 - an Armstrong Whitworth 122 hp 0-4-0 diesel-electric shunter delivered in 1934 [12] - and reached 840 in 1991. South African locomotive numbering and classification, https://en.wikipedia.org/w/index.php?title=South_African_Class_NG_G11_2-6-0%2B0-6-2&oldid=1126751041, Use South African English from November 2013, All Wikipedia articles written in South African English, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 11 December 2022, at 01:37. The term "Mallet" continued to be widely used for simple as well as compound locomotives. NG113 and Hunslet-Taylor-built no. The weight of the front part of the boiler was to be supported on an arc-shaped radial bearing. Built in 1926, the Garratt locos almost had the tractive effort of a K Class, on a narrow gauge line. 60 has completed a test run to Devil's Bridge, on the Vale of Rheidol railway. [13] and included one locomotive experimentally converted to electric traction. 58 Rio Grande No. whilst the power units have been rebuilt at Dinas. 2644 and Class 26 no. [1][2][8], Having been proved successful during trials, another two locomotives were ordered from Beyer, Peacock. Dragon emblems were later mounted on the cab sides and bunker ends. Narrow Gauge Garratt locomotives Herbert Garratt - and his Sandstone locomotives An iconic Sandstone scene. [13], Both superheated locomotives still exist. MV 401[hu] was a (1B)B locomotive in service between 19051969 and MV 651[hu] 0-6-6-0 until 1962. [2] Since then, various types of diesel locomotives were added to the service. The exhaust steam from these cylinders was fed into a . More Pictures > 400 Captions 26, 32. As of January 2023, No. To accommodate the pivoting, the steam and exhaust pipes have flexible connections between the engine units and the central cradle. [1][2][8][9], With the GPCS, the coal is heated to drive off the volatile components which are then burned in the secondary air admitted above the grate. (There was a proposal, late in the steam era, for a 3'6" gauge East African Garratt which would have been a large locomotive even by U.S. standard . [1][2], The seven Beyer, Peacock locomotives ordered by the Tsumeb Copper Corporation, numbers NG137 to NG143, were initially distributed between the Umzinto, Port Shepstone and Avontuur lines, but in 1964 the three that went to the Langkloof were also transferred to Natal. Fully upholstered, heated and double glazed coach delivered to Dinas in September 1997 for the start of the Caernarfon service. The lower-pressure steam occupies a larger volume and the low-pressure (LP) cylinders are larger than the high-pressure cylinders. Running numbers 99 5901-3 and 99 5906 are in working order. The Harding line was privatised in 1988 as the Alfred County Railway (ACR), operating out of Port Shepstone. [2], Ex South African Railways NGG16 Class Garratt. This has been supplemented by later information as it became available. Three of their Class NG G16 locomotives are homed here, and are regularly run during the Estate's annual events like the Cosmos Festival, Cherry Festival, Stars of Sandstone and others. [10] This system was abandoned in 1928,[10] with new locomotives being numbered from 249 upwards,[11] and reaching 336 by 1940, and 362 in 1951 when the last steam locomotive a 4-8-0 from WG Bagnall was delivered. By about 1920, the U.S. version of the Mallet as a huge slow-speed pusher had reached a plateau; the size of the low-pressure cylinders became a limiting factor even on the large loading gauge permitted in the U.S., and reciprocating masses posed serious dynamic problems above walking pace. This then was what became understood as a "Mallet" locomotive: an articulated locomotive in which the rear set of driving wheels were fixed in the main frame of the locomotive; an articulated truck carrying a second set of driving wheels; and compounding in which the high-pressure cylinders drove the axles on the main frame and the articulated axles were driven by low-pressure steam. Narrow Gauge 400 class-class 4-8-2+2-8-4 Garratt locomotives 400 class 400 to 409 Jump to: The 400 class class 4-8-2+2-8-4 type Garratt locomotives were built for use on the South Australian Railways narrow gauge system between Port Pirie and Broken Hill hauling heavy ore trains. The locomotive has a Gardner 8LW diesel engine de-rated to 132hp. Chattenden and Upnor Railway. Power car is a single-ended locomotive without passenger interiors. In service on newly refurbished bogies. Total rebuild carried out including a new all-welded steel boiler and conversion to 2'6" gauge. [citation needed]. These U.S. locomotives were paralleled to some extent by heavy-haul versions in the USSR, though without any attempt at faster running. In terms of a prior agreement between the SAR and the Tsumeb Copper Corporation, the SAR would purchase any narrow gauge locomotives that would become redundant should the re-gauging of the SWA system take place. Only Garratt to get to Quorn [, Worked to Broken Hill. This created the risk of the locomotive tilting over on tight curves. Power cars are single-ended locomotives without passenger interiors. After several years on light duties a new engine was fitted in October 1999. Ex South African Railways NGG16 Class Garratt, green livery. Withdrawn in 2020 for a ten-yearly overhaul. Only Garratt to do so. NG51 later. After first being steamed in September 2019 129, in November 2019 it underwent light engine and load testing.[14][15]. NG127 from Peter Newton in November 2011. [1][5], Unlike tender locomotives, Garratts are bi-directional, which eliminates the need for turntables or triangles, also known as wyes. [2][7], The final order for eight locomotives in 1967, numbered in the range from NG149 to NG156, turned out to be the last new steam locomotives to be ordered by the SAR. That proposal, however, never became reality since the line's farming produce traffic was gradually lost to road transport on the improving road network, a decline which eventually led to the ACR's demise. Located in the former Humewood Road (Port Elizabeth) Narrow Gauge diesel depot in good external condition. [2][3][7], However, while the locomotives were being built, the decision was made to convert all the SWA narrow gauge lines to Cape gauge. [12], The other two were scrapped after being retired from SAR service. This saw its first operation in Europe in 2011 and after initial trials on the owners' railway, was transferred to the Welsh Highland Railway as its power is better suited to that railway. The ASG was to be a suitable narrow gauge locomotive aimed at easing a chronic shortage of motive power on the various state 3'6" gauge systems, which was a result of the advent of World War 2. Vaughan, then Chief Mechanical Officer and Assistant to the CPR Vice-President. 0-4-4-0 metre gauge Mallet built by Maschinenbau-Gesellschaft Karlsruhe, operated commercially by the Zell im WiesentalTodtnau railway and as of 2021 preserved and still operating at the BlonayChamby museum railway. The BlonayChamby museum railway has two Mallets. However this limited cater locomotives from SLR for some services. We still hope for this engine to be preserved in railway museums, but there is a chance to make a new built of the class. No. NG55 at Ixopo, KwaZulu-Natal, 4 June 2005, The compact Walschaerts valve gear on NG G11 no. When fleets of such locomotives appeared in the middle 1920s the trade press called them "Simple Mallets" i.e., simple locomotives articulated like Mallets. Arrived on the WHR 18 February 2010. This 180hp Gardner 6LXB diesel-engined locomotive was built for RNAD Ernesettle, Plymouth. In addition, the articulated design of the earlier models, as well as the most powerful, the 1956 model locomotive with its 4-8-2+2-8-4 axle arrangement, enabled it . The Mallet locomotive is a type of articulated steam railway locomotive, invented by the Swiss engineer Anatole Mallet (18371919). 155, was rebuilt in 1990, but it retained its traditional ex-SAR black livery. Entered service in plain black livery in 1998, but was due for boiler recertification in 2009. Now in service. Porta. Commenced service on the Puffing Billy Railway in December 2019 before being withdrawn again for further work. To achieve this, the amount of air being drawn up through the firebed is minimised, while the main sources of air required for combustion is through secondary air inlets located in the firebox sides and through the vertically sliding firedoor. [6], Probably the greatest advantage of the Garratt was that, with its boiler and grate area suspended between two engine units without the need to leave room for coupled wheels and cylinders, wide and deep fireboxes with large grate areas and large diameter boilers were possible. Built by Societe Franco-Belge builders No.2977, Beyer Peacock builders No.7626. Note piston valves on high-pressure cylinders and slide valves on low-pressure cylinders. Their engine numbers, builders, years built and works numbers are listed in Table II. Arrived ex ship "Belnor". [, Worked to Quorn. All are diesel hydraulic type except DLW locomotive which is diesel electric. As weight and power and length increased, there were experiments with flexible boiler casings; from 1910 the Santa Fe road introduced jointed-boiler 2-6-6-2 locomotives weighing 392,000lb (178,000kg), with a 37 feet (11.28m) long boiler barrel, with a firetube reheater and a firetube feedwater section in front, each separated by a blank section, and variants of a telescopic or bellows type boiler casing. Withdrawn from service in 2020, awaiting a replacement boiler for a new ten year ticket. Both modified locomotives were reclassified to Class NG G16A. NG55 was stored in the open at Ixopo awaiting extensive boiler repairs. 729 ex demonstrator, ran as DR V150.001; imported 1970. It was taken out of service in October 2010 due to mechanical problems and retired from the Union Pacific's excursion program in January 2020. Large numbers of Mallet designs for narrow gauge railways were built, but in 1889 the first six standard gauge examples were built by J A Maffei for the Swiss Central railways, and an 87 tonne 0-6-6-0T banker (US: pusher) for the Gotthard Bahn, the last being the most powerful and heaviest locomotive in the world at the time.
