Track (rail transport)

The track on a railway or railroad, also known as the permanent way, is the structure consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll. For clarity it is often referred to as railway track (British English and UIC terminology) or railroad track (predominantly in the United States). Tracks where electric trains or electric trams run are equipped with an electrification system such as an overhead electrical power line or an additional electrified rail.

The term permanent way also refers to the track in addition to lineside structures such as fences etc.

Structure

Traditional track structure

Notwithstanding modern technical developments, the overwhelmingly dominant track form worldwide consists of flat-bottom steel rails supported on timber or pre-stressed concrete sleepers, which are themselves laid on crushed stone ballast.

Fidelipac

The Fidelipac, commonly known as a "NAB cartridge" or simply "cart", is a magnetic tape sound recording format, used for radio broadcasting for playback of material over the air such as radio commercials, jingles, station identifications, and music. Fidelipac is the official name of this industry standard audio tape cartridge. It was developed in 1954 by inventor George Eash (although the invention of the Fidelipac cartridge has also been credited to Vern Nolte of the Automatic Tape Company), and commercially introduced in 1959 by Collins Radio at the 1959 NAB Convention. The cartridge was widely used at radio stations until the late 1990s, when such formats as MiniDisc and computerized broadcast automation made the Fidelipac cartridge obsolete.

History

The Fidelipac cartridge was the first audio tape cartridge available commercially, based on the endless-loop tape cartridge design developed by Bernard Cousino in 1952, while Eash shared space in Cousino's electronics shop in the early 1950s. Instead of manufacturing the Fidelipac format himself after developing it, Eash decided to license it for manufacture to Telepro Industries, in Cherry Hill, New Jersey. Telepro then manufactured and marketed the format under the Fidelipac brand name.

100 euro note

The one hundred euro note (€100) is one of the higher value euro banknotes and has been used since the introduction of the euro (in its cash form) in 2002. The note is used daily by some 332 million Europeans and in the 23 countries which have it as their sole currency (with 22 legally adopting it).

It is the third largest note measuring 147 millimetres (5.8 in) × 82 millimetres (3.2 in) and has a green colour scheme. The hundred euro notes depict bridges and arches/doorways in the Baroque and Rococo style (between the 17th and 18th century).

The hundred euro note contains several complex security features such as watermarks, invisible ink, holograms and microprinting that document its authenticity. In May 2012, there were approximately 1,652,287,100 hundred euro banknotes in circulation in the eurozone.

History

The euro was founded on 1 January 1999, when it became the currency of over 300 million people in Europe. For the first three years of its existence it was an invisible currency, only used in accountancy. Euro cash was not introduced until 1 January 2002, when it replaced the national banknotes and coins of the countries in eurozone 12, such as the French franc and the Spanish peseta.

1 euro coin

The 1 euro coin is a euro coin with a value of one euro (€1). It is made of two alloys: the inner part of cupronickel, the outer part of nickel brass. All coins have a common reverse side and country-specific national sides. The coin has been used since 2002, with the present common side design dating from 2007.

As of July 2015, there were approximately 6.7 billion one euro coins in circulation, constituting 26.4% of all circulated euro coins by value and 5.9% by quantity.

History

The coin dates from 2002, when euro coins and banknotes were introduced in the 12 member Eurozone and its related territories. The common side was designed by Luc Luycx, a Belgian artist who won a Europe-wide competition to design the new coins. The design of the one and two euro coins was intended to show the European Union (EU) as a whole with the then 15 countries more closely joined together than on the 10 to 50 cent coins (the 1 to 5 cent coins showed the EU as one, though intending to show its place in the world).

10 euro note

The ten euro note (€10) is the second-lowest value euro banknote and has been used since the introduction of the euro (in its cash form) in 2002. The note is used in the 23 countries which have it as their sole currency (with 22 legally adopting it); with a population of about 332 million.

It is the second-smallest note measuring 127x67mm with a red colour scheme. The ten euro banknotes depict bridges and arches/doorways in Romanesque architecture (between the 11th and 12th centuries).

The ten euro note contains several complex security features such as watermarks, invisible ink, holograms and microprinting that document its authenticity. In September 2011, there were approximately 2,005,149,600 ten euro banknotes in circulation around the eurozone.

History

The euro was founded on 1 January 1999, when it became the currency of over 300 million people in Europe. For the first three years of its existence it was an invisible currency, only used in accountancy. Euro cash was not introduced until 1 January 2002, when it replaced the national banknotes and coins of the countries in eurozone 12, such as the Italian lira and the German mark.
