15-401: Common to all the variants was the B axle arrangement (European or UIC classification ) or 0-4-0 ( Whyte notation ), the semi-automatic, gravity-feed firing that enabled one-man operation, and platforms with guard rails, front and rear, that enabled safe access to the coaches. The locomotives had a large driver's cab with 3 windows per side that surrounded the entire locomotive boiler as far as

30-634: A jackshaft and external connecting rods . Unlike the better-known later variants the water tank of this 'ancient glass box' ( Ur-Glaskasten ) was arranged over the gangway, but in such a way that crossing over to the coaches in the train was still possible. A rival design for this locomotive was the Bavarian ML 2/2 that was built by Maffei. In the Reichsbahn's provisional renumbering plan of 1923, all six locomotives were included as numbers 98 301 - 98 306; they were however taken out of service in

45-617: A locomotive dealer and the Lower Saxon State Railway Office to the Verden-Walsrode Railway . They had it modified in 1947 at Krupp's : the armatures were moved to the rear of the outer firebox and housed in a normal driver's cab; gravity-fed firing was converted to normal firing with a firebox door. This work was completed in 1950 in Verden, before it went into service as locomotive no. 298. On

60-583: Is used in much of the world, notable exceptions being the United Kingdom and North America . The classification system is managed by the International Union of Railways (UIC). The UIC uses the following structure: Garratt locomotives are indicated by bracketing or placing plus signs between all individual units. The most common wheel arrangements in modern locomotives are Bo′Bo′ and Co′Co′. The following examples are based on

75-802: The Austrian Federal Railways ( Österreichische Bundesbahn ). This engine was taken out of service in 1959. The remaining locomotives entered the Deutsche Bundesbahn , and were mostly withdrawn during the 1950s. Number 98 307 was deployed until 1963 between Spalt and Georgensgmünd and was known as the 'Spalter Goat' ( Spalter Bockel ). It has been preserved and is kept at the German Steam Locomotive Museum ( Deutsches Dampflokomotiv-Museum or DDM ) in Neuenmarkt - Wirsberg on loan from

90-671: The Nuremberg Transport Museum ( Verkehrsmuseum Nürnberg ), but is no longer working. A second engine, numbered "4515", had been cut in cross-section to explain the internal workings of a steam locomotive. It was an unfortunate victim of the great fire at the Nuremberg Shed in October 2005, but after a successful renovation is now displayed in the DB Museum, Koblenz . In 1938 locomotive no. 98 321 went via

105-480: The smokebox . This unique feature earned it the nickname Glaskasten ("glass box") or, in Franconia , Glas-Chaise ("glass carriage"). In both 1905 and 1906 Krauss supplied three locomotives (numbers 4501–4506) with an inside driving gear arranged inside the frame and between the axles. The three machines built in 1906 had their cylinder diameter increased from 285 to 305 mm. The two axles were driven via

120-664: The European UIC classification scheme (except for small diesel shunters, where Whyte notation is used). In mainland Europe , the UIC classification scheme is generally used for all locomotive types including steam, with some exceptions. In France , the UIC classification is used for diesels and electrics while a scheme similar to the Whyte notation, but counting axles instead of wheels, is used for steam locomotives. Notably, Switzerland had its own separate notation system until 1989, with

135-567: The UIC classification: Wheel arrangement In rail transport , a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive . Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country. Within a given country, different notations may also be employed for different kinds of locomotives, such as steam , electric , and diesel powered. Especially in steam days, wheel arrangement

150-575: The axles or the bogies ), and the UIC classification of locomotive axle arrangements (based on counting either the axles or the bogies). Whyte notation is generally used for steam locomotives throughout the United States , Canada , the United Kingdom and Ireland . For diesels and electrics, North America uses the AAR wheel arrangement scheme while British practice uses a slightly simplified form of

165-507: The running plate, two former air cylinders were mounted as additional water tanks. Its period of duty was short, however. By early 1956 the locomotive was taken out of service and sold to a scrap merchant. UIC classification The UIC classification of locomotive axle arrangements , sometimes known as the German classification or German system , describes the wheel arrangement of locomotives , multiple units and trams . It

180-413: The same year. The reason for that was the difficulty of accessing the inside driving gear for maintenance work. In 1908 and 1909 Krauss supplied 29 locomotives with a conventional outside driving gear, which nevertheless used a jack shaft between the main axles. They were given locomotive numbers 4507 to 4535. This driving gear enabled the water tank to be located below the boiler in the frame, so that there

195-526: The versions built up to 1909. The Deutsche Reichsbahn-Gesellschaft took over 22 locomotives, numbering them 98 301 - 98 322. Nine of these came from the first series with the jackshaft. Two locomotives were sold to industrial firms in 1942, one was a victim of the Second World War and the engine number 98 304 stayed in Austria after the war. It was designated as Class ÖBB 688.01 by

210-529: Was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven. The main notations are the Whyte notation (based on counting the wheels), the AAR wheel arrangement notation (based on counting either

225-656: Was more space on the gangways. Three further locomotives of this type were procured by the Prussian state railways in 1910 and were designated as the Prussian Class T 2 . In 1911 and 1914 two further batches of nine and four locomotives were supplied to the Royal Bavarian State Railways. On these, the jackshaft was left out and the wheelbase reduced from 3,200 mm to 2,700 mm. These engines were also shorter overall and lighter than
