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. Darjeeling Himalayan Railway D Class Beyer-Garratt "Union Pacific Big Boy", an example of a simple Mallet. Numbers 1 and 2: 2-6-0/0-6-2 Beyer Peacock Garratt acquired new in 1936/38. NG55, 4 June 2005, NG G11 no. The Alfred County Railway Class NG G16A 2-6-2+2-6-2 of 1989 is a steam locomotive from the South African Railways era. between 1995 and 2002 with numbers RB1 to RB14. They had outside plate frames, Walschaerts valve gear, Belpaire fireboxes and used saturated steam and slide valves. When fleets of such locomotives appeared in the middle 1920s the trade press called them "Simple Mallets" i.e., simple locomotives articulated like Mallets. The weight of the front part of the boiler was to be supported on an arc-shaped radial bearing. This created the risk of the locomotive tilting over on tight curves. [8] The AT&SF also had a number of compound 2-10-10-2's, assembled in their own shops from existing 2-10-2's using a kit, supplied by Baldwin, consisting of the front 10-wheel frame and a boiler extension. Another De Winton is on display in the entrance to the WHR Caernarfon Station. This was further worsened by dynamic instability of the front end in running. Power car is a single-ended locomotive without passenger interiors. The object of the latter is to convert the kinetic energy of the combustion gas and exhaust steam mixture to a pressure as close to atmospheric as possible. Arrived ex ship "Belnor". [2] Since then, various types of diesel locomotives were added to the service. [4], On the South African Railways (SAR) narrow gauge lines, that solution was found in 1914 when orders were placed with Beyer, Peacock and Company for a narrow-gauge Garratt locomotive. Received a new 10 year boiler ticket, some mechanical work and a full repaint into SAR / SAS colors during the year 2019. Finished in U.K. Pullman Car Company livery. [1][9], One visible difference between the original and the rebuilt locomotives is the megaphone-shaped Lempor chimney, which contains a cylindrical mixing chamber and a wide angled diffuser. It was in service until 1979, and as of September 2021 is still under restoration. The following locomotives are normally Ffestiniog Railway stock that have run on the WHR. [citation needed]. The Beyer-Garratt was particularly well-suited for rail lines of narrow gauge with lightly laid tracks because the weight of the locomotive was spread over a considerable distance. Diesel locomotives and multiple unit numbering started from 500 an Armstrong Whitworth 122hp 0-4-0 diesel-electric shunter delivered in 1934[12] and reached 840 in 1991. On this Wikipedia the language links are at the top of the page across from the article title. G41 was put to work on the Colac to Beach Forest and Crowes line in the states (Victoria) south-west. Slightly shorter but even heavier and more powerful were 2-6-6-6s built by Lima for the C&O and the Virginian between 1941 and 1948, which weighed 778,000lb (353,000kg) and could produce up to 6,900 horsepower (5,100kW) at 45mph (72km/h). 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][2][7], The Hunslet-Taylor locomotives, numbers NG149 to NG156, were placed in service on the Harding and Donnybrook branches in Natal in 1968. GM Detroit Diesel V16 engine. [4], Throughout its history, Ceylon Government Railway had 410 steam locomotives. The new locomotives were therefore delivered directly to the SAR in 1958. These are the most powerful narrow gauge locos in the world, which is necessary to cope with the hard gradients of up to 1 in 40 along the line pulling up to 12 coaches. [, Worked to Quorn. The first locomotive to undergo the treatment was the Beyer, Peacock-built no. [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.

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. [11] Several however, have now been cut up for scrap (see table below). It was planned to use them as tank-and-tender Garratts, semi-permanently attached to a water tender for use across the Namib desert in SWA, as was the practice with the Cape gauge Classes GM, GMA and GO tank-and-tender Garratts in South Africa. It would have been most interesting if Alco would have been able to sell a few Garratts to D&RGW for the narrow gauge lines. Converted steam rail car in 1950. 20 All items (468) # A B C D E Fitted with Pullman style armchairs. All the steam locomotives bar three were manufactured in the United Kingdom; the exceptions were three 4-4-0s built at the railway's Maradana Works near Colombo in 1900 and 1905. These U.S. locomotives were paralleled to some extent by heavy-haul versions in the USSR, though without any attempt at faster running. Chattenden and Upnor Railway. NG51 was put on trials on the Avontuur line in May 1920. Back in operation by April 2019 after a boiler retube. Purchased from Exmoor Steam Centre, who imported it to the UK. [1], Ejector pump efficiency depends on the length-to-diameter ratio of the exhaust chimney. It was still at Sandstone in July 2017, stored indoors in reasonable condition awaiting a THF decision on whether to leave it at Sandstone or return it to Humewood Road. 60 arrived via a low-loader back in July 2017 . Withdrawn in 2020 for a ten-yearly overhaul. Several units out of service shortly after introduction due to cost of spares and repair. All three, numbered in the range from NG51 to NG53, were erected at the Uitenhage workshops and no. Sixteen "Beyer-Garratt" locomotives of the 4-8-0 + 0-8-4 type are in service on the 5 ft. 6 in. [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. Extensive gallery of narrow gauge railway photos. Some parts including the British built Hunslet boiler used to make 116 whole. The final Garratt locomotive built at Gorton works, South African Railways NG/G16 No.143 is also now at the Welsh Highland Railway. History [ edit] 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. Altogether 34 more 2-6-2+2-6-2 Double Prairie type narrow gauge locomotives were built, spread over five orders from three manufacturers over a span of 32 years. On this Wikipedia the language links are at the top of the page across from the article title. [1][2][8], Having been proved successful during trials, another two locomotives were ordered from Beyer, Peacock. "Societe Franco-Belge De Materiel Des Chemins De Fer Raismes, France" built 4-8-2+2-8-4 type narrow gauge Garratt steam locomotive. Challenger #3985 was the largest operational steam locomotive in the world until the restoration of UP 4014. In 2017, at least four establishments still operated or were restoring ex-SAR Class NG G16 Garratts. Built by Societe Franco-Belge builders No.2977, Beyer Peacock builders No.7626. [1][2], When the lower section of the Avontuur line was dieselised upon the arrival of the Class 91-000 diesel-electric locomotives in 1973, all the Class NG G16 locomotives still in service were transferred to various branches in Natal, where they remained until they were withdrawn from service. The lower-pressure steam occupies a larger volume and the low-pressure (LP) cylinders are larger than the high-pressure cylinders. Updated start of season 2020.[10]. NG87 and Beyer, Peacock-built numbers NG130, NG138 and NG143, are used for operational purposes. is now at Paton County Narrow Gauge Railway . G42 was located on the Moe to Walhalla line in the states south-east. [2], On the Avontuur Railway, these locomotives were used as tank-and-tender Garratts, but when the Langkloof members of the class were transferred to Natal in 1964, the water tenders were dispensed with since watering points were much closer together in Natal as a consequence of the early use of tank engines on those narrow-gauge branches. Not to be confused with the steam locomotive E1, this electric locomotive is not in commercial use. In Canada, the Canadian Pacific Railway experimented with an unusual design of Mallet promoted by H.H. This page was last edited on 4 August 2022, at 12:33. The cost of the work paid off financially within twelve months and led to a proposal to develop a Class NG G17, but that never materialised since the line's farming produce traffic was gradually lost to road transport on the improving road network. NG129's restoration was planned to coincide with the next time that no. Ten-yearly overhaul was completed in 2020, with the locomotive now painted in South African Railways black with SAR/SAS logo on the coal bunker. Arrived ex ship "Belnor". 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. Electrification has been proposed, to improve energy efficiency and sustainability.[9]. Built for the North Wales Narrow Gauge Railways became Welsh Highland Railway property in 1923 and was reduced in height to fit the FR loading gauge. [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. These are Cockerill-built no. 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. These locomotives were introduced in 1926 to increase train sizes and thus reduce losses on . These new locomotives took over service on a 113-mile (182km) division; a single locomotive hauled 9,500 short tons (8,600t; 8,500 long tons) in five hours.[3]. [13] and included one locomotive experimentally converted to electric traction. 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. One class P1 locomotive was at Viharamahadevi (Victoria) Amusement Park[14], S1S8 Diesel Hydraulic Multiple Units, S9S14, S14A Diesel Electric & Electro-Diesel Multiple Units. G42 was to be withdrawn for major maintenance. Power outputs of over 700 indicated horsepower was achieved and the locomotive was probably capable of achieving a maximum of 800 indicated horsepower, some 25% more than the Class 91-000 narrow gauge diesel-electric locomotive. Although less obvious, both Wardale GPCS locomotives, Class 19D no. The largest compound Mallets were ten 2-10-10-2s built for the Virginian by Alco in 1918; in pairs they pushed coal trains headed by a 2-8-8-2.
