G41 was put to work on the Colac to Beach Forest and Crowes line in the states (Victoria) south-west. [citation needed]. [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. Imported in two variants, one for run on commuter services and other run on long distance services. - last, Entered service as "407". When they were designated Class NG G16, the "NG/G13" was altered to "NG/G16" by milling out the 3 and riveting on a 6, as shown. The last compound Mallets to remain in use on a major North American railroad were the N&W class Y6b 2-8-8-2 locomotives, retired in July 1959. is now at Paton County Narrow Gauge Railway . The model represents the Garratt locomotives presently running on the Welsh Highland Railway. [citation needed], The Welsh Highland Railway in Wales has five Class NG G16 locomotives. Photo credit: David Benn section of surviving Narrow Gauge Garratt locomotives in the world. CC 50 22, an early Dutch-built Indonesian Mallets has been returned to the Netherlands and is now exhibited in the Dutch Railway Museum but meanwhile, the other 2 like CC 50 01 is preserved in Transportation Museum in TMII and CC 50 29 is preserved in the Ambarawa Railway Museum. Total rebuild carried out including a new all-welded steel boiler and conversion to 2'6" gauge. Typically they feature horizontal bands of colour running their entire length and a solid colour on the front and back ends. "The Ultimate Steam Page P.

Fully upholstered, heated and double glazed coach delivered to Dinas in September 1997 for the start of the Caernarfon service. They still had elliptical tops on the water tanks and both tank and bunker were riveted as per the pre-war machines, however on the boiler the location of the safety valves, clack valves and main manifold (amongst other details) changed to what would become the standard for all remaining builds. Since then, the Railways have imported locomotives from Canada, Japan, West Germany, India, France, and China[6][7][8]. [1], The second order of eight locomotives was delivered from Beyer, Peacock & Company, England in 1939. The final Garratt locomotive built at Gorton works, South African Railways NG/G16 No.143 is also now at the Welsh Highland Railway. Explore. Locomotive is for sale. [citation needed]. HAL6DTI - 135 hp. NG5 as yard shunter at Humewood Road. [2][9][10], The first three locomotives were all working in Natal soon after entering service. "[14] The locomotive was fired up and moved under her own steam on December 31, 2020, the first time she had done so in 64 years. More Pictures > 400 This is a list of the rolling stock owned by the Ffestiniog Railway Company which is used to operate the Welsh Highland Railway, Ex Tasmanian Government Railways K class, the world's first Garratt locomotive. [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. Built in 1967 and 1968, these locomotives had the same enlarged capacity front water tanks as those of the Tsumeb group, but their rear bunkers were identical to those of the 1951 batch of locomotives and carried both coal and water. Arrived ex ship "Belnor". 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. [4] [14] These are Cockerill-built no. It is believed to have been stored in Essex and in Somerset before being moved to the Exmoor Steam Railway. Some are the locomotives owned by Sri Lanka Ports Authority and Holcim Sri Lanka limited. NG55 was restored to full working order also at Bloemfontein for the Patons Country Narrow Gauge Railway (PCNGR) at Ixopo in Natal by 2005. Unlike other diesels purchased by the Ffestiniog Railway Company and named bilingually after Northern Welsh castles, 'Castell Caernarfon' is named in Welsh only. As water and coal is consumed, the weight over the coupled wheels is reduced, thereby reducing their factor of adhesion, the ratio of weight on coupled wheels to tractive effort. The American engineer W. S. Hudson patented a system of compounding for railway locomotives in 1873[1] in which he proposed an intermediate receiver surrounded by hot gas from the fire, so that the low-pressure steam is partly superheated. A development of the Winson Engineering carriages delivered in 1997, including wider door opening for easier access to passengers with reduced mobility. The compound steam system fed steam at boiler pressure to high-pressure cylinders driving the rear set of driving wheels (rigidly connected to the boiler). This created the risk of the locomotive tilting over on tight curves. [, Entered service as "408". No 23 returned to FR service in 1955 and full doors fitted in 1966. 2644 and Class 26 no. These three locomotives were not superheated. Only the boiler cradle and cab are today genuine 156. Owned by Transnet Heritage Trust. 482 Rio Grande No. We would like to show you a description here but the site won't allow us. Re-entered service in 2010 in crimson lake livery. The Class NG G16 rebuilding incorporated a gas producing combustion system (GPCS), Lempor exhausts, an improved spark arrester, lightweight multi-ring articulated piston valves, improved valve events and improved mechanical lubrication. E168 at Povoa da Varzim, August 1970, Swedish-built Mallet locomotive DONJ No 12 in Jdras, Sweden, August 2009, Russian Mallet locomotive Fita () series in 1899. The Puffing Billy Railway also purchased no. Between 1937 and 1968, the South African Railways placed 34 Class NG G16 Garratt articulated 2-6-2+2-6-2 steam locomotives in service on the Avontuur Railway and on the Natal narrow gauge lines. [13] This gave them a second almost-complete Class NG G16 which will possibly also be totally rebuilt in the future. Another 2 WDG4D locomotives are to be arrived. Both modified locomotives were reclassified to Class NG G16A. 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. This page was last edited on 2 January 2023, at 00:53. 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. Ex South African Railways NG15 Class Unrestored. Power car is a single-ended locomotive without passenger interiors. Subsequent to the exchange, the number "24" was allocated to Ashbury "Corridor" No. Some are not in use. Hitachi Tourist excursion train. At the time, the PCNGR was operating tourist excursion trains between Ixopo and Ncalu. 143's bogies were both taken out of service and the loco ran on 138's bogies until it left service. Entered service in plain black livery in 1998, but was due for boiler recertification in 2009. MV 401[hu] was a (1B)B locomotive in service between 19051969 and MV 651[hu] 0-6-6-0 until 1962. 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. Locomotive 491 is truly a "Colorado original" having been built entirely in Colorado during the spring of 1928 through a cooperative effort between the Stearns-Roger Manufacturing Company of Denver and the D&RGW Denver Burnham Shops. Spent much of its working life in South Africa until it was replaced by diesel traction. [, Worked to Quorn. 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. [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. Only Garratt to do so. Steam under pressure is converted into mechanical energy more efficiently if it is used in a compound engine; in such an engine steam from a boiler is used in high-pressure (HP) cylinders and then under reduced pressure in a second set of cylinders. The last Garratt built by. Built by Baguley as a 2ft gauge locomotive with the builders number 2395. In 2004 the locomotive was purchased by a member of the Lynton & Barnstaple Trust, who shipped it from Australia in 2005. No. Porta. Moreover, there were adhesion stability problems where the front engine tended to slip and then stall uncontrollably because of an imbalance of tractive effort and axle load, accentuated by the drawbar reaction, and inability of the intermediate steam receiver to accommodate the sudden pressure change. 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. Between 1937 and 1968, the South African Railways placed 34 Class NG G16 Garratt articulated 2-6-2+2-6-2 steam locomotives in service on the Avontuur Railway and on the Natal narrow gauge lines. This was the last locomotive built by Beyer, Peacock and Company in Manchester. Some have transferred for regular service, to cover for maintenance and traction requirements before there were enough dedicated WHR locomotives to operate the passenger service, others were for construction purposes only. On December 17, 2021, C&O 1309 (now WMSR 1309) entered excursion service on the Western Maryland Scenic Railroad. In February 2020 it was announced that 141 would give up its 16A power units to make 155 whole with 141 being cosmetically restored at some point in time using available standard NG16 parts at Sandstone. After retirement at the mine, it was preserved at the Museum of Man and Science in Johannesburg in 1974, then moved to the Klein Jukskei Motor Museum by 1981 and finally donated to the South African National Railway And Steam Museum (SANRASM). 58 Rio Grande No. NG51 later. Either method was expensive and, in such conditions, the Garratt design had distinct advantages. G42 was located on the Moe to Walhalla line in the states south-east. Class of South African 26-2+2-6-2 Garratt locomotives, South African Railways and Harbours Locomotive Diagram Book, 2'0" & 3'6" Gauge Steam Locomotives, 15 August 1941, as amended, Rebuilt Garratt undertakes its first Australian run, SATS / Transnet NG/G16 Garratt Fleet Disposal, Stars of Sandstone, Official Operating Programme for 12th - 21st April 2014. In contrast to the rest of the Indonesian railways it has a gauge of 750mm (2ft5+12in), as to 1,067mm (3ft6in) for the rest of the Archipelago. When fleets of such locomotives appeared in the middle 1920s the trade press called them "Simple Mallets" i.e., simple locomotives articulated like Mallets. Weighing 71.25 tons, they were initially used on the main quarry line until replaced by the diesel, later being used as shunters. [3], The London and North Western Railway locomotive engineer F W Webb adopted the idea and converted some existing locomotives in 1879, followed by de Glehn and others in the 1880s and several American engineers in the 1890s which included some vertical boiler railcar applications. A Garratt is therefore a single locomotive with double the tractive effort and, with its weight distributed over a long and flexible multi-axle wheelbase, a lower axle loading. Therefore, as the weight on the coupled wheels decreases, the locomotive has less adhesion and becomes increasingly prone to slipping. NG129's restoration was planned to coincide with the next time that no. Three Mallets ran in Australia, including one on the Magnet Tramway in Tasmania. Transferred to Dinas in March by rail using the CTRL. Water was carried in the front and rear tanks and also unusually, in a tank under the boiler. [13] and included one locomotive experimentally converted to electric traction. This was further worsened by dynamic instability of the front end in running. In 2017, at least four establishments still operated or were restoring ex-SAR Class NG G16 Garratts. Built by Societe Franco-Belge builders No.2975, Beyer Peacock builders No.7624. [1], In comparative testing, no. [1][2][3], The system of grouping narrow-gauge locomotives into classes was only adopted by the SAR somewhere between 1928 and 1930. [2][4], These pre-war locomotives, like the earlier Class NG G13 locomotives, were built with riveted coal and water bunkers and with elliptical tops on the water tanks.
