Draisine

A draisine is a light auxiliary rail vehicle, driven by service personnel, equipped to transport crew and material necessary for the maintenance of railway infrastructure. The eponymous term is derived from the German inventor Baron Karl Drais, who invented his Laufmaschine in 1817, called Draisine in German by the press, it is the first reliable claim for a used precursor to the bicycle the first commercially successful two-wheeled, human-propelled machine, nicknamed hobby-horse or dandy horse. The name draisine came to be applied only to the invention used on rails and was extended to similar vehicles when not human-powered; because of their low weight and small size, they can be put on and taken off the rails at any place, allowing trains to pass. In the United States, motor-powered draisines are known as speeders while human-powered ones are referred as handcars. Vehicles that can be driven on both the highway and the rail line are called road–rail vehicles, or Hy-Rails. "Draisines", called dressin in Swedish, dresin in Norwegian, dræsine in Danish, resiina in Finnish, refers to pedal-powered rail-cycles which were used by railroad maintenance workers in Finland and Norway until about 1950, as handcars were elsewhere.

Draisines nowadays are used for recreation on several unused railway lines in Germany, Norway, some other European countries and South Korea. Several companies rent draisines in Sweden. In the United States, railbike tours have operated in several states nationwide: Maine, the Adirondack Mountains of upstate New York, Delaware; until 2007, Finland hosted an annual competition, Resiina-ralli, involving several draisine teams travelling for many days on the railways from one corner of the country to another. The military usage of draisines concerned, first of all, armoured draisines, they were light armoured rail motor vehicles, intended for reconnaissance, track patrolling, other auxiliary combat tasks belonging to armoured trains. Early vehicles of this kind were built in Russia during World War I. Armoured cars were used as armoured draisines, after exchanging their wheels to railroad ones, or fitting them with additional retractable railroad rollers; some countries, manufactured purpose-built armoured draisines between the wars, such as the USSR and Czechoslovakia.

Peculiar vehicles were Polish armoured draisines - they were tanks or tankettes fitted with special rail chassis, able to be used on rails or on the ground, leaving the rail chassis on the rails. Some countries developed railtrack armoured draisines, with retractable tracks railroad wheels. Different armoured draisines were used during the Second World War, starting from the invasion of Poland carried out by Nazi Germany. Prior to World War II, the Japanese Empire had made extensive use of draisines such as the Sumida M.2593 in Manchuria and the Sino-Japanese war. People have been putting bicycles on railroad tracks since there have been both bicycles and railroads. From time to time, factory-built models have been available, beginning with a device marketed in 1908 through the Sears catalogue for just US$5.45. There are many designs of draisine. However, certain fundamentals of railbike design must be adhered to, foremost among them the reconciliation of a bicycle's stability with adaptation to riding on a railway track: bicycles are kept upright by the rider steering in the direction of an impending fall, but this ability is sacrificed when the bicycle is constrained by rails.

Adding flanged wheels to a conventional bicycle would make it impossible to balance, so the typical approach to stabilization is to add an outrigger, with roller, across to the second rail from near the bicycle’s rear wheel. Such an outrigger system is not without its complications, as tracks that are no longer parallel — common on sections of abandoned track — can result in derailment. Additional guide rollers can help alleviate this problem at the expense of greater weight.

Excluding its closing credits, the special features the last four tracks from the album America by Dan Deacon. The episode incorporates the following works, which center on landscapes in the United States: El hombre y la Tierra excerpt Radical Updates by Andrew Benson Cityscape Chicago by Eric Hines Space Station footage provided by Image Science and Analysis Laboratory at the NASA John Space Center Groosland by Dutch National Ballet CGI space objects by Adam Bruneau American Harvest provided by Prelinger Archives Head On by Lior Ben Horin Murmuration by Liberty Smith and Sophie Windsor Clive Cy's Sunrise Lefts by Cyrus Sutton and Korduroy.tv Moonwalk performance by Dean Potter Primavera Concert Footage by Tom Bingham, Gill Austin, Jonathan Rej, Jeff Crocker Stone Mountain Ghillie Suits.

Deacon's track was released on William Street Record's website on June 26, 2013. Despite the special's national focus, the episode culls works from artists worldwide. Hughes, along with associate producer Cody DeMatteis, utilized Adobe After Effects for some aspects of post-production editing; the special makes extensive use of compression artifacts for artistic effect, namely "datamoshing", where two videos are interleaved so intermediate frames are interpolated from two separate sources. The technique referred to as "photo stacking", in which time-lapse photographs are composited on top of one another, was utilized for the NASA John Space Center footage. "Dan Deacon: U. S.
