V12 engines have often been used in Formula One, particularly from the 1966 season to the 1969 season . The first V12 engine used in Formula One was in the 1964 Honda RA271 racing car, and continued through to the 1968 Honda RA301 racing car. The 1966 season saw V12 engines become popular, with new V12 engines from Ferrari, Maserati, and Weslake. Ferrari's engine debuted in
384-485: A GB+ loading gauge refers to the plan to create a pan-European freight network for ISO containers and trailers with loaded ISO containers. These container trains ( piggy-back trains ) fit into the B envelope with a flat top so that only minor changes are required for the widespread structures built to loading gauge B on continental Europe. A few structures on the British Isles were extended to fit with GB+ as well, where
480-444: A V-angle of 60 degrees between the two banks of cylinders. V12 engines with other V-angles have been produced, sometimes using split crankpins to reduce the unbalanced vibrations. The drawbacks of V12 engines include extra cost, complexity, friction losses, and external size and weight, compared with engines containing fewer cylinders. At any given time, three of the cylinders in a V12 engine are in their power stroke, which increases
576-446: A V12 racing engine could be lighter than a crossplane V8 engine of similar displacement due to the V12 engine not requiring counterweights on the crankshaft or as much inertial mass for the flywheel. In addition, the exhaust system of a V12 engine is much simpler than would be required for a crossplane V8 engine to achieve pulsed exhaust gas tuning. However, the use of V12 engines in motor racing
672-470: A currently produced V12 marine engine is the Wärtsilä 46F engine, where the V12 version has a displacement of 1,157 L (70,604 cu in) and a power output of 14,400 kW (19,300 hp). Renault introduced the first V12 engine for aircraft with their 90 hp model of 1912 . This engine had a V-angle of 60 degrees, air cooling and an intake over exhaust (F-head) valve arrangement. The propeller

Two more V12s appeared in the 1909-1910 motor boat racing season. The Lamb Boat & Engine Company in the United States built a 25.5 L (1,559 cu in) engine for the company's 10 m (32 ft) 'Lamb IV' boat. The Orleans Motor Company built
864-401: A displacement of 9.0 L (549 cu in), an aluminum crankcase, iron cylinders with L-shaped combustion chambers, a cam-in-block valvetrain and a V-angle of 60 degrees. Each bank of the engine consisted of two-cylinder blocks with three cylinders each. Valve clearance was set by grinding the relevant parts, the engine lacking any easy means of adjustment. This reflected the intention for
960-541: A height limit of 5,850 mm (19 ft 2 in). Metre gauge in China has a gauge of 3,050 mm (10 ft 0 in). Translation of legend: Trains on the Shinkansen network operate on 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) standard gauge track and have a loading gauge of 3,400 mm (11 ft 2 in) maximum width and 4,500 mm (14 ft 9 in) maximum height. This allows

Some of the new railways being built in Africa allow for double-stacked containers, the height of which is about 5,800 mm (19 ft 0 in) depending on the height of each container 2,438 mm (8 ft 0 in) or 2,900 mm (9 ft 6 in) plus
1344-402: A massive 56.8 L (3,464 cu in) flathead V12 engine with a power output quoted as "nearly 298 kW (400 bhp)". In 1914, Panhard built two 38.6 L (2,356 cu in) V12 engines with four valves per cylinder, which were designed for use in racing boats. Large V12 diesel engines are common in modern cruise ships, which may have up to six such engines. An example of

Above the platform gate height of 1,200 mm (3 ft 11 in) above the platforms, out-of-gauge installations can be further maximized to the Asian standard at 3,400 mm (11 ft 2 in). Meanwhile, the PNR South Long Haul will follow the Chinese gauge and therefore use
1536-457: A plethora of different private companies, each with different standards for the width and height of trains. After nationalisation, a standard static gauge W5 was defined in 1951 that would virtually fit everywhere in the network. The W6 gauge is a refinement of W5, and the W6a changed the lower body to accommodate third-rail electrification. While the upper body is rounded for W6a with a static curve, there
1632-425: A potential engine option for its first-ever front-wheel-drive car, Cadillac Eldorado . However, Cadillac was unsatisfied with the performance of its V12 engine, having little advantage over the large displacement V8 that was cheaper to enlarge for more power. In Europe, several manufacturers added V12 engines to their line-up, as listed below: In the United States, no mass-produced V12 engines have been built since
1728-650: A prototype version of the Sunbeam Mohawk V12 engine was unveiled in the United Kingdom, based on the 'Toodles V' motor racing engine. The production version was rated at 168 kW (225 hp) at 2,000 rpm, making it the most powerful airplane engine in Great Britain at the outbreak of World War I. During and after World War I, various companies in the United States produced the Liberty L-12 engine. In Austria,
1824-419: A specification for standard coach stock, gauge C3 for longer Mark 3 coaching stock, gauge C4 for Pendolino stock and gauge UK1 for high-speed rail. There is also a gauge for locomotives. The size of container that can be conveyed depends both upon the size of the load that can be conveyed and the design of the rolling stock. A strategy was adopted in 2004 to guide enhancements of loading gauges and in 2007
1920-601: A standard series of loading gauges named A, B, B+ and C. In the European Union , the UIC directives were supplanted by ERA Technical Specifications for Interoperability (TSI) of European Union in 2002, which has defined a number of recommendations to harmonize the train systems. The TSI Rolling Stock (2002/735/EC) has taken over the UIC Gauges definitions defining Kinematic Gauges with a reference profile such that Gauges GA and GB have
2016-471: A strict static gauge for the wagons, their sizes are derived from dynamic gauge computations for rectangular freight containers. Network Rail uses a W loading gauge classification system of freight transport ranging from W6A (smallest) through W7, W8, W9, W9Plus, W10, W11 to W12 (largest). The definitions assume a common "lower sector structure gauge" with a common freight platform at 1,100 mm (43.31 in) above rail. In addition, gauge C1 provides

#17328758804422112-404: A very small loading gauge, which reduces the cost of tunnel construction. These systems only use their own specialised rolling stock. Larger out-of-gauge loads can also sometimes be conveyed by taking one or more of the following measures: The loading gauge on the main lines of Great Britain, most of which were built before 1900, is generally smaller than in other countries. In mainland Europe,
2208-402: Is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. Classification systems vary between different countries, and loading gauges may vary across a network, even if
2304-456: Is an additional small rectangular notch for W7 to accommodate the transport of 2.44 m (8 ft 0 in) ISO containers, and the W8 loading gauge has an even larger notch spanning outside of the curve to accommodate the transport of 2.6 m (8 ft 6 in) ISO containers. While W5 to W9 are based on a rounded roof structure, those for W10 to W12 define a flat line at the top and, instead of
2400-539: Is called the clearance . The specified amount of clearance makes allowance for wobbling of rail vehicles at speed. The loading gauge restricts the size of passenger coaches, goods wagons (freight cars) and shipping containers that can travel on a section of railway track. It varies across the world and often within a single railway system. Over time there has been a trend towards larger loading gauges and more standardization of gauges; some older lines have had their structure gauges enhanced by raising bridges, increasing
2496-509: Is common as locomotive, armoured tank, and marine engines. In these applications, the width of the engine is constrained by tight railway clearances or street widths , while the length of the vehicle is more flexible. In twin-propeller boats, two V12 engines can be narrow enough to sit side by side, while three V12 engines are sometimes used in high-speed three-propeller configurations. Large, fast cruise ships can have six or more V12 engines. In historic piston-engine fighter and bomber aircraft,
2592-400: Is currently no uniform standard for loading gauges in the country and both loading gauges and platform heights vary by rail line. The North–South Commuter Railway allows passenger trains with a carbody width of 3,100 mm (10 ft 2 in) and a height of 4,300 mm (14 ft 1 in). Additional installations shall also be allowed up to 3,300 mm (10 ft 10 in) at
2688-481: Is discussed under narrow gauge , below. The body frame may have a maximum height of 4,500 mm (14 ft 9 in) and a maximum width of 3,400 mm (11 ft 2 in) with additional installations allowed up to 3,600 mm (11 ft 10 in). That width of 3,400 mm is only allowed above 1,250 mm (4 ft 1 in) as the common passenger platforms are built to former standard trains of 3,200 mm (10 ft 6 in) in width. There
2784-633: Is generally acceptable as the extra width is above normal platform height, but it means that they can not use the high platforms that Arlanda Express uses ( Arlanda Central Station has normal clearances). The greater width allows sleeping cars in which tall people can sleep with straight legs and feet, which is not the case on the continent. In the Netherlands, a similar shape to the UIC C is used that rises to 4.70 m (15 ft 5 in) in height. The trains are wider allowing for 3.40 m (11 ft 2 in) width similar to Sweden. About one third of

The prevalence of excess-height rolling stock, at first ~18 ft (5.49 m) piggybacks and hicube boxcars , then later autoracks , airplane-parts cars, and flatcars for hauling Boeing 737 fuselages, as well as 20 ft 3 in (6.17 m) high double-stacked containers in container well cars , has been increasing. This means that most, if not all, lines are now designed for

3072-404: Is uncommon in the 21st century. A 60-degree V12 engine is typically narrower than a 90-degree V6 or V8 engine of similar displacement. However, the V12 engine is usually longer than V6 and V8 engines. The added length often makes it difficult to fit a V12 engine into a passenger car, but the length is not typically a problem for trucks and stationary applications. Due to its narrower width, the V12
3168-538: The Austro Daimler V12 engines were used by the large flying boats of the Naval Air Force and produced up to 257 kW (345 hp). By the end of World War I, V12s were well established in aviation, powering some of the newest and largest fighter and bomber airplanes. After World War I, many Zeppelins used V12 engines built by Maybach and Daimler . V12 engines powered the first transatlantic crossings by
3264-642: The Battle of Britain . The long, narrow configuration of the V12 contributed to good aerodynamics, while its smoothness allowed its use with relatively light and fragile airframes. In the United States, the Rolls-Royce Merlin engine was produced under license by Packard Motor Car Company, which was used in the P-51 Mustang fighter. This engine was also incorporated into some models of the Curtiss P-40, specifically

Maserati's engine was introduced in the Cooper T81 and was used until the 1969 Cooper T86 . The Weslake V12 engine was used from 1966 to 1968 and was introduced in the Eagle Mk1 racing car. BRM produced V12 engines from the 1968 BRM P133 racing car until the 1977 BRM P207 . The Matra Sports V12 engine
3456-633: The Green Line (known as the Tremont Street subway ) was constructed in 1897 to take the streetcars off Boston 's busy downtown streets. When the Blue Line opened in 1904, it only ran streetcar services; the line was converted to rapid transit in 1924 due to high passenger loads, but the tight clearances in the tunnel under the Boston Harbor required narrower and shorter rapid transit cars. The Orange Line

In 1935, the V12 engine used by the Pierce Arrow luxury car was fitted to firetrucks built by Seagrave (with production continuing until 1970, since Seagrave purchased the equipment to manufacture the Pierce Arrow engines themselves). The 1960–1965 GMC Twin Six 11.5 L (702 cu in) gasoline V12 engine was basically the GMC 351 V6 engine, doubled, with four rocker covers and four exhaust manifolds. Peak power

The term loading gauge can also be applied to the maximum size of road vehicles in relation to tunnels , overpasses and bridges , and doors into automobile repair shops , bus garages , filling stations , residential garages , multi-storey car parks and warehouses . A related but separate gauge is the structure gauge , which sets limits to the extent that bridges, tunnels and other infrastructure can encroach on rail vehicles. The difference between these two gauges
4128-639: The turbosupercharger system required bulky ductwork and had poor high-altitude performance. In 1943, a version using a more conventional mechanical supercharger began production. After World War II, V12 engines became generally obsolete in aircraft due to the introduction of turbojet and turboprop engines that had more power for their weight, and fewer complications. In automobiles, V12 engines are less common than engines with fewer cylinders, due to their size, complexity, and cost. They have been mostly used for expensive sports and luxury cars thanks to their power, smooth operation, and distinctive sound. One of

In Japan, Isuzu produced naturally aspirated V12 diesel engines from 14.0 to 22.0 L (854 to 1,343 cu in) in 1976–2000, for their heavy duty trucks: New Power, 810 and Giga. Trucks using V12 gasoline (petrol) engines are rare, however several were produced in the United States from the 1930s until the 1970s. In 1931, American La France began producing firetrucks with V12 gasoline engines based on
4800-442: The 1995 Ferrari 412 T2 became the last Formula One car to use a V12 engine. The Lamborghini LE3512 engine was used by various teams between 1989 and 1993. The Honda RA122-E engine was first used in the 1991 McLaren MP4/6 and was raced until the 1992 McLaren MP4/7A . The Yamaha OX99 engine was used in the 1990 Brabham BT59 through to the 1992 Brabham BT60 . The most powerful naturally-aspirated V12 engine used in Formula One

#17328758804425952-449: The United States. During the late 1920s, the number of marques offering V12 engines for their passenger cars increased and peaked in the 1930s. The lack of vibration and sound, inherent smoothness, and increased power were cited as key benefits for V12 engines. Automobile petrol produced in the 1920s and 1930s had lower octane rating , leading to lower engine performance ratings, and vibration isolating engine mounts were rarely fitted to
6048-632: The V12 layout was commonly adopted due to its low vibrations so that the powerful engines did not tear apart the light airframes of fighters. The Allied forces used V12 engines with an "upright" design, while many German engines (aside from the BMW VI , which was designed prior to World War II), used an inverted engine design, which had a lower centre of gravity and improved pilot visibility for single-engined designs.

It was named 'Toodles V' (after Coatalen's pet name for his wife) and achieved several speed records in 1913 and 1914. The V12 engine had
6432-437: The engine to be later used in aircraft since any adjustment method that could go wrong in flight was to be avoided. As initially built, the V12 was rated at 150 kW (200 bhp) at 2,400 rpm and weighed approximately 340 kg (750 lb). Amongst the first production cars to use a V12 engine were the 1915 Packard Twin Six , the 1915 National V12 engine and the 1917 Weidely Pathfinder ; all of which were built in
6528-499: The entry point to a restricted part of a network. The devices ensure that loads stacked on open or flat wagons stay within the height/shape limits of the line's bridges and tunnels, and prevent out-of-gauge rolling stock entering a stretch of line with a smaller loading gauge. Compliance with a loading gauge can be checked with a clearance car . In the past, these were simple wooden frames or physical feelers mounted on rolling stock. More recently, laser beams are used. The loading gauge
6624-544: The existing British network, rather than being purchased "off-the-shelf". For example, the new trains for HS2 have a 50% premium applied to the "classic compatible" sets that will be "compatible" with the current (or "classic") rail network loading gauge as well as the HS2 line. The "classic compatible" trainsets will cost £40 million per trainset whereas the HS2-only stock (built to European loading gauge and only suitable to operate on HS2 lines) will cost £27M per trainset despite
6720-503: The first lines to be rebuilt start at the Channel Tunnel . Owing to their historical legacies, many member states' railways do not conform to the TSI specification. For example, Britain 's role at the forefront of railway development in the 19th century has condemned it to the small infrastructure dimensions of that era. Conversely, the loading gauge s of countries that were satellites of
6816-523: The former BMT and IND systems ( B Division ) from running on the lines of the former IRT system ( A Division ), and vice versa. This is mainly because IRT tunnels and stations are approximately 1 foot (305 mm) narrower than the others, meaning that IRT cars running on the BMT or IND lines would have platform gaps of over 8 inches (203 mm) between the train and some platforms, whereas BMT and IND cars would not even fit into an IRT station without hitting
6912-607: The former Eastern Division , the cars are limited to 60 feet (18.29 m), while on the rest of the BMT and IND lines plus the Staten Island Railway (which uses modified IND stock) the cars may be as long as 75 feet (22.86 m). The Massachusetts Bay Transportation Authority 's (MBTA) rapid transit system is composed of four unique subway lines; while all lines are standard gauge, inconsistencies in loading gauge, electrification, and platform height prevent trains on one line from being used on another. The first segment of
7008-420: The former Soviet Union are much larger than the TSI specification. Other than for GB+, they are not likely to be retrofitted, given the enormous cost and disruption that would be entailed. A specific example of the value of these loading gauges is that they permit double decker passenger carriages. Although mainly used for suburban commuter lines, France is notable for using them on its high speed TGV services:
7104-425: The height and width of tunnels and making other necessary alterations. Containerisation and a trend towards larger shipping containers has led rail companies to increase structure gauges to compete effectively with road haulage. The term "loading gauge" can also refer to a physical structure, sometimes using electronic detectors using light beams on an arm or gantry placed over the exit lines of goods yards or at
7200-399: The increase of truck centers, the decrease of width is covered by AAR Plates D1 and D2 . Listed here are the maximum heights and widths for cars. However, the specification in each AAR plate shows a car cross section that is chamfered at the top and bottom, meaning that a compliant car is not permitted to fill an entire rectangle of the maximum height and width. Technically, AAR Plate B
7296-653: The initial system. It is composed of two heavy rail subway lines and several light rail lines with subway sections; while all lines are standard gauge, inconsistencies in electrification and loading gauge prohibit the light rail trains from operating on the heavy rail lines, and vice versa. The LACTC-planned Blue Line was opened in 1990 and partially operates on the route of the Pacific Electric interurban railroad line between downtown Los Angeles and Long Beach, which used overhead electrification and street-running streetcar vehicles. The SCRTD-planned Red Line (later split into
7392-478: The long, narrow V12 configuration used in high-performance aircraft made them more streamlined than other engines, particularly the short, wide radial engine . The first V-engine (a V-twin design) was built by Daimler in 1889, then the first V8 engine was built by Antoinette in 1903. These were followed by the first V12 engine in 1904, which was built by Putney Motor Works in London for use in racing boats. Known as
7488-423: The network, such as auto carriers , hi-cube boxcars , and double-stack container loads . The maximum width of 10 ft 8 in (3.25 m) on 41 ft 3 in (12.57 m) ( AAR Plate B ), 46 ft 3 in (14.10 m) ( AAR Plate C ) and all other truck centers (of all other AAR Plates) are on a 441 ft 8 + 3 ⁄ 8 in (134.63 m) radius or 13° curve. In all cases of
7584-628: The operation of double-deck high-speed trains. Mini Shinkansen (former conventional 1,067 mm or 3 ft 6 in narrow gauge lines that have been regauged into 1,435 mm or 4 ft 8 + 1 ⁄ 2 in standard gauge ) and some private railways in Japan (including some lines of the Tokyo subway and all of the Osaka Metro ) also use standard gauge; however, their loading gauges are different. The rest of Japan's system
7680-466: The passenger cars in the 1920s and the early 1930s. Adding more cylinders to the engine was one of several techniques for performance increase. European passenger cars with V12 engines were: American passenger cars with V12 engines were: The economic hardships caused the Great Depression meant that all American automakers except for Lincoln had discontinued production of V12 engines by the end of
7776-411: The platform edge. Taking this into account, all maintenance vehicles are built to IRT loading gauge so that they can be operated over the entire network, and employees are responsible for minding the gap . Another inconsistency is the maximum permissible railcar length. Cars in the former IRT system are 51 feet (15.54 m) as of December 2013 . Railcars in the former BMT and IND can be longer: on
7872-482: The reliability and crudeness of his Ferrari 250 GT, Ferruccio Lamborghini wanted to develop his own passenger cars that were more cultured and more reliable than the cars produced by Ferrari. His first passenger car, a grand tourer, was 350 GT with 3.5 L (214 cu in) DOHC engine. Both manufacturers have a long history of producing vehicles with V12 engines, which continues uninterrupted to this day. Cadillac experimented with V12 engines in 1963 and 1964 as
7968-408: The same platform. The size of load that can be carried on a railway of a particular gauge is also influenced by the design of the rolling stock. Low-deck rolling stock can sometimes be used to carry taller 9 ft 6 in (2.9 m) shipping containers on lower gauge lines although their low-deck rolling stock cannot then carry as many containers. Rapid transit (metro) railways generally have
8064-468: The slightly larger Berne gauge (Gabarit passe-partout international, PPI) was agreed to in 1913 and came into force in 1914. As a result, British trains have noticeably and considerably smaller loading gauges and, for passenger trains, smaller interiors, despite the track being standard gauge , which is in line with much of the world. This often results in increased costs for purchasing new trainsets or locomotives as they must be specifically designed for
8160-420: The smoothness of the power delivery by eliminating gaps between power pulses. A V12 engine with a 180 degree V-angle is often called a flat-twelve engine . These are also sometimes called 'boxer twelve' engines, however this terminology is incorrect for the majority of 180-degree V12 engines, since they use shared crankpins and are therefore not configured as boxer engines. Theoretically, the rotating parts of
8256-527: The track – are sometimes used in place of loading gauge. The railway platform height is also a consideration for the loading gauge of passenger trains. Where the two are not directly compatible, stairs may be required, which will increase loading times . Where long carriages are used at a curved platform, there will be gaps between the platform and the carriage door , causing risk. Problems increase where trains of several different loading gauges and train floor heights use (or even must pass without stopping at)
8352-639: The winch is 100 meters, and the winch is able to provide 15 tons of traction. The vehicle is powered by a 12-cylinder D-12A-525A diesel engine located directly behind the cab. This engine provides preheating as well. The drivetrain of the MAZ-537 consists of a hydrodynamic transmission transferring power to the two front axles over a torque converter and a planetary three-stage gearbox with assisted steering (power steering) gear. The MAZ-537 has been widely used in both military roles (as, for example, artillery tractor trailer (pulling rocket or (ballistic) missile launchers), tank transporter, and airfield tractor) and in
8448-441: Was built in 1904 for use in racing boats . Due to the balanced nature of the engine and the smooth delivery of power , V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in
8544-559: Was driven from the front end of the camshaft, thus spinning the propeller speed at half the speed of a typical crankshaft driven propeller, in order to improve the propeller efficiency. The Renault engine was closely mimicked by the RAF 4 and its derivatives, which was used by various British military aircraft during World War I. The RAF 4 engine had a displacement of 13.2 L (806 cu in), weighed 289 kg (637 lb) and produced 104 kW (140 hp) at 1,800 rpm. In March 1914,
8640-499: Was introduced in the 1968 Matra MS11 racing car and used until the 1978 Ligier JS9 . Few V12 engines were used in the following decade, with the exception of the Alfa Romeo V12 which was first used by the 1979 Brabham BT48 and then by Alfa Romeo until the 1982 Alfa Romeo 182 . A resurgence of V12 engines in Formula One began in 1989, with the introduction of the Ferrari 640 racing car. Ferrari continued to use V12 engines until
8736-578: Was only 250 hp (186 kW). However peak torque was 793 N⋅m (585 lb⋅ft). Many diesel locomotives use V12 engines. Examples include the 2.39 MW (3,200 hp) EMD 12-710 and the 3.28 MW (4,400 hp) GEVO-12 engine (used in the GE ES44AC North American locomotives). V12 engines used in railway locomotives include: The V12 is a common engine configuration for tanks and other armoured fighting vehicles . Some examples are: Loading gauge A loading gauge
8832-653: Was originally built in 1901 to accommodate heavy rail transit cars of higher capacity than streetcars. The Red Line was opened in 1912, designed to handle what were for a time the largest underground transit cars in the world. The Los Angeles Metro Rail system is an amalgamation of two former constituent companies, the Los Angeles County Transportation Commission and the Southern California Rapid Transit District; both of those companies were responsible for planning
8928-478: Was particularly active in the construction of military railways which were often built with great expense to be as flat, straight and permissive in loading gauge as possible while bypassing major urban areas, making those lines of little use to civilian traffic, particularly civilian passenger traffic. However, all those aforementioned factors have in some cases led to the subsequent abandoning of those railroads. The International Union of Railways (UIC) has developed
9024-453: Was the Tipo 043 , used by Ferrari in 1994 , which produced 850 hp (630 kW) @ 15,800 rpm. In prototype sports car racing, the highly successful 2006–2008 Audi R10 TDI used a diesel twin-turbo V12 engine. The Peugeot 908 HDi FAP , introduced in 2007, also used a diesel twin-turbo V12 engine. Several truck manufacturers have produced V12 diesel engines at various times. For example,
9120-599: Was the air-cooled Ranger V-770 , which was used in aircraft that were only used for training purposes within the United States, such as the Fairchild AT-21 Gunner . The Rolls-Royce Merlin V12 engine was used in several British aircraft including the Hawker Hurricane and Supermarine Spitfire fighters, and the Avro Lancaster and de Havilland Mosquito bombers. The Hurricane and Spitfire played vital roles in
9216-602: Was the first electrified railway line in Sweden and has limited height clearance (SE-B) because of snow shelters. On the rest of the network belonging to the Swedish Transport Administration ( Trafikverket ), the structure gauge accepts cars built to SE-A and thus accepts both cars built to UIC GA and GB. Some modern electric multiple units, like Regina X50 with derivatives, are somewhat wider than normally permitted by SE-A at 3.45 m (11 ft 4 in). This
