	Raxles - Glossary
		A back-to-back arrangement of two Cardan universal joints sometimes used on RWD driveshaft to reduce driveshaft vibrations.
		The tendency of a FWD vehicle to pull to one side or to pull in the direction the wheels are steered when engine torque is applied.
		Also called a tripod or tripode joint, this is a type of CV joint that uses three roller bearings mounted on the three trunnions of a tripod to carry torque to an outer "tulip" housing (so called because of its lower-like shape).

	AAR wheel arrangement Information
		The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads.
		This arrangement also includes locomotives made of two permanently coupled B-B units, such as some EMD FT units which had a solid drawbar connecting two units instead of the typical couplers.
		This arrangement was used on the Jawn Henry coal-fired steam-turbine locomotive built by the Baldwin Locomotive Works for the Norfolk and Western Railway in May, 1954.

	Wheel arrangement - Biocrawler (Site not responding. Last check: )
		Wheel arrangement, in the field of railroad locomotives, is how the wheels of the locomotive are arranged by type, position, and connections.
		The United States uses the AAR wheel arrangement scheme for diesels and electrics.
		Especially in steam days, wheel arrangement was an important attribute of a locomotive, because there were many different ones, each optimised for a different use.

	Online Encyclopedia and Dictionary - Driving wheel (Site not responding. Last check: )
		On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive).
		On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod ; power is transmitted to the others through the side rods.
		The driving wheel on tracked vehicles (such as tank or bulldozer) is a large chain wheel that moves the track and rotates it around it.

		Six driving wheels (three axles) were fitted towards the center of the locomotive on each truck (twelve in total) and a four-wheeled, unpowered guiding truck was mounted toward each end.
		This arrangement is called 2-C+C-2 in AAR wheel arrangement notation.
		The locomotive's power was controlled via a tap-switching arrangement; the number of secondary windings in use could be varied, thus adjusting the output voltage.

	Trailing wheel - Slider (Site not responding. Last check: )
		On a steam locomotive, a trailing wheel or trailing axle is an unpowered wheel or axle located behind the driving wheels.
		Trailing wheels were used in some early locomotives but fell out of favor for a time during the latter 19th century.
		The trailing wheel supported the firebox allowing it to be longer and wider increasing firebox surface area which allowed higher possible boiler pressures which allowed locomotives to produce more power.

	Leading wheel Information
		On a steam locomotive, a leading wheel or leading axle is an unpowered wheel or axle located in front of the driving wheels.
		The first use of leading wheels is commonly attributed to the 4-2-0 designs of John B. Jervis in 1832 (a locomotive type that has since become known as the Jervis type).
		The highest number of leading wheels on a single locomotive is six as seen on the 6-2-0 Crampton type and the Pennsylvania Railroad's 6-4-4-6 S1 duplex locomotive and 6-8-6 S2 steam turbine.

		The Whyte notation for classifying steam locomotives by wheel arrangement was devised by Frederick Methvan Whyte and came into use in the early 20th century.
		Thus, a locomotive with two leading axles (and thus four wheels) in front, then three driving axles (six wheels) and followed by one trailing axle (two wheels) is classified as a 4-6-2.
		Here is a list of the most common wheel arrangements: in the illustration the front of the locomotive is to the left, o is a carrying axle, O a driving axle.

	Encyclopedia :: encyclopedia : Span bolster (Site not responding. Last check: )
		The most common use on locomotives is to give a more flexible alternative to a four-axle truck; two two-axle trucks linked by a span bolster allows the wheels to follow a curve better, without excessive side forces or the need for lateral motion of the axles in the truck.
		The use of a span bolster is normally signified in the AAR wheel arrangement notation by a + sign; thus a locomotive with two span bolsters, each with two two-axle trucks (the most common arrangement) is a B+B-B+B. Span bolsters have also been used for some high-capacity freight cars.
		The most common use is for large flatcars to haul large, heavy loads; these cars need large numbers of axles to spread the weight.

		The UIC classification is a comprehensive system for describing the wheel arrangement of locomotives, multiple units and trams.
		It is the system generally used in much of the world, but it was not widely used in the United Kingdom, other than partially on the Southern Railway under chief engineer Oliver Bulleid, or in the United States; a simplified form (AAR wheel arrangement) is used in both countries for modern locomotives.
		The most common wheel arrangements in modern locomotives are Bo'Bo' or Co'Co', while steam locomotives and other older units can have many different wheel arrangements.

	Trailing wheel - Definition, explanation
		Some locomotives such as the 4-4-0 American type had no trailing wheels and were designated with a zero in the final place.
		In the Whyte notation the number designates the number of wheels rather that the number of axles, thus the final 2 in the Mikado's 2-8-2 refers to two wheels (one axle) while the Northern type's 4-8-4 designation refers to four wheels (two axles).
		The highest number of trailing wheels on a single locomotive is six as seen on the 2-6-6-6 Allegheny type and the Pennsylvania Railroad's 6-8-6 steam turbine and 6-4-4-6 duplex locomotives.

		This arrangement is known as a quill drive, in reference to the hollow part of a bird feather, and is very common in France.
		Each axle, threaded through its respective hollow shaft, is driven by a "spider" pushing on the wheel through a spring and rubber block arrangement.
		This fact was not lost upon the French test personnel even before the locomotive ever turned a wheel on American rails, but in the end there was no suspension adjustment that provided satisfactory performance under all service conditions.
