A train station, railway station, railroad station, or depot is a railway facility or area where trains stop to load or unload passengers or freight. It consists of at least one track-side platform and a station building providing such ancillary services as ticket sales and waiting rooms. If a station is on a single-track line, it has a passing loop to facilitate traffic movements; the smallest stations are most referred to as "stops" or, in some parts of the world, as "halts". Stations elevated. Connections may be available to intersecting rail lines or other transport modes such as buses, trams or other rapid transit systems. In British English, traditional usage favours railway station or station though train station, perceived as an Americanism, is now about as common as railway station in writing. In British usage, the word station is understood to mean a railway station unless otherwise qualified. In American English, the most common term in contemporary usage is train station. In North America, the term depot is sometimes used as an alternative name for station, along with the compound forms train depot, railway depot, railroad depot, but applicable for goods, the term depot is not used in reference to vehicle maintenance facilities in American English.
The world's first recorded railway station was The Mount on the Oystermouth Railway in Swansea, which began passenger service in 1807, although the trains were horsedrawn rather than by locomotives. The two-storey Mount Clare station in Baltimore, which survives as a museum, first saw passenger service as the terminus of the horse-drawn Baltimore and Ohio Railroad on 22 May 1830; the oldest terminal station in the world was Crown Street railway station in Liverpool, built in 1830, on the locomotive hauled Liverpool to Manchester line. As the first train on the Liverpool-Manchester line left Liverpool, the station is older than the Manchester terminal at Liverpool Road; the station was the first to incorporate a train shed. The station was demolished in 1836 as the Liverpool terminal station moved to Lime Street railway station. Crown Street station was converted to a goods station terminal; the first stations had little in the way of amenities. The first stations in the modern sense were on the Liverpool and Manchester Railway, opened in 1830.
Manchester's Liverpool Road Station, the second oldest terminal station in the world, is preserved as part of the Museum of Science and Industry in Manchester. It resembles a row of Georgian houses. Early stations were sometimes built with both passenger and goods facilities, though some railway lines were goods-only or passenger-only, if a line was dual-purpose there would be a goods depot apart from the passenger station. Dual-purpose stations can sometimes still be found today, though in many cases goods facilities are restricted to major stations. In rural and remote communities across Canada and the United States, passengers wanting to board the train had to flag the train down in order for it to stop; such stations were known as "flag stops" or "flag stations". Many stations date from the 19th century and reflect the grandiose architecture of the time, lending prestige to the city as well as to railway operations. Countries where railways arrived may still have such architecture, as stations imitated 19th-century styles.
Various forms of architecture have been used in the construction of stations, from those boasting grand, Baroque- or Gothic-style edifices, to plainer utilitarian or modernist styles. Stations in Europe tended to follow British designs and were in some countries, like Italy, financed by British railway companies. Stations built more often have a similar feel to airports, with a simple, abstract style. Examples of modern stations include those on newer high-speed rail networks, such as the Shinkansen in Japan, THSR in Taiwan, TGV lines in France and ICE lines in Germany. Stations have staffed ticket sales offices, automated ticket machines, or both, although on some lines tickets are sold on board the trains. Many stations include a convenience store. Larger stations have fast-food or restaurant facilities. In some countries, stations may have a bar or pub. Other station facilities may include: toilets, left-luggage, lost-and-found and arrivals boards, luggage carts, waiting rooms, taxi ranks, bus bays and car parks.
Larger or manned stations tend to have a greater range of facilities including a station security office. These are open for travellers when there is sufficient traffic over a long enough period of time to warrant the cost. In large cities this may mean facilities available around the clock. A basic station might only have platforms, though it may still be distinguished from a halt, a stopping or halting place that may not have platforms. Many stations, either larger or smaller, offer interchange with local transportation. In many African, South American countries, Asian countries, stations are used as a place for public markets and other informal businesses; this is true on tourist routes or stations near tourist destinations. As well as providing services for passengers and loading facilities for goods, stations can sometimes have locomotive and rolling stock depots (usually with facilities for storing and refuelling rolling stock an
Des Plaines, Illinois
Des Plaines is a city in Cook County, United States. Its population was 58,364 at the 2010 census; the city is located just north of O'Hare International Airport. It is situated on and is named after the Des Plaines River, which runs through the city just east of its downtown area. Potawatomi and Ojibwe Native American tribes inhabited the Des Plaines River Valley prior to Europeans' arrival; when French explorers and missionaries arrived in the 1600s in what was the Illinois Country of New France, they named the waterway La Rivière des Plaines as they felt that trees on the river resembled the European plane trees. The first white settlers came from the eastern United States in 1833, after the Treaty of Chicago, followed by many German immigrants during the 1840s and'50s. In the 1850s, the land in this area was purchased by the Illinois and Wisconsin Land Company along a railroad line planned between Chicago and Janesville, Wisconsin. In 1852, the developers built a steam-powered mill next to the river to cut local trees into railroad ties.
Socrates Rand bought the mill and converted it into a grist mill, which attracted local farmers. The Illinois and Wisconsin Railroad made its first stop in the area in the fall of 1854. In 1857, the Chicago, St. Paul, Fond du Lac Railroad began running its route, stopping near the mill on the Des Plaines river, where a small business section had grown up; the railroad platted the prospective town of Rand at the site. In 1859, the Chicago and North Western Railway purchased the rail line, giving the train station the name "Des Plaines". In 1869, the Rand subdivision's name was changed to Des Plaines, the village of Des Plaines was incorporated. Des Plaines was elected a village board the following year. Local brick manufacturer Franklin Whitcomb served as the first Village President. In 1925, village residents voted to convert to a city form of government and annexed the village of Riverview to the south. Subsequent annexations included the Orchard Place area in 1956; the city experienced rapid growth after World War II and with the opening of nearby Chicago-O'Hare International Airport.
Des Plaines was the site of Ray Kroc's first McDonald's franchise, which opened in 1955. The restaurant was demolished in 1984, a replica was built on the site as a museum dedicated to McDonald's history. In 2017, McDonald's announced plans to demolish the building due to repeated flooding. In 1979, Des Plaines was the site of the accident of American Airlines Flight 191, in which a McDonnell Douglas DC-10 departing from O'Hare lost an engine and wing material and crashed near a local trailer park just north of Touhy Avenue. All 271 people onboard. Two more, along with three civilians, were injured. In 2008, the Illinois Gaming Board awarded the state's 10th and last casino license to Midwest Gaming and Entertainment LLC to build a 140,000-square-foot casino on 21 acres adjacent to the Tri-State Tollway at the northwest corner of Devon Avenue and Des Plaines River Road. Midwest Gaming received the award despite having the lowest bid because other bidders were found unacceptable by the Board, with one board member finding no bidders acceptable.
The city approved zoning in early 2010, the casino opened in July 2011 as Rivers Casino. Des Plaines is located at 42°2′2″N 87°53′59″W. According to the 2010 census, Des Plaines has a total area of 14.415 square miles, of which 14.28 square miles is land and 0.135 square miles is water. Des Plaines is traversed by two interstate highways – I-90 and I-294. Des Plaines is named for the Des Plaines River; the name is from 18th-century French referencing the American sycamore which resembles the European plane tree. Portions of Des Plaines are underlain by the "Des Plaines Disturbance", an area in which the layers of sedimentary rock are abnormal; this represents an ancient meteorite crater, 75 to 200 feet beneath the town. The bedrock was fractured by the impact, with large blocks of sediment upended; the crater was filled by glacial activity, so that no trace now remains on the surface. Addresses in the city limits of Des Plaines have their own numbering system. Areas in unincorporated Maine Township have Des Plaines postal addresses that follow the Chicago numbering system.
Devon Avenue in Des Plaines is 3200 South. Golf Road runs through a large unincorporated area as 9600 North with a Des Plaines mailing address but is 0 North/South when entering the Des Plaines city limits; as sections become incorporated, they take on the city numbering system. For instance in 2003, land at 9661 West Golf Road, Des Plaines, became 2323 East Golf Road, Des Plaines, when it was formally incorporated into the city limits; the largest unincorporated areas are in the O'Hare area and east of the Tri-State Tollway. As of the census of 2000, there were 58,720 people, 22,362 households, 15,071 families residing in the city; the population density was 4,071.2 people per square mile. There were 22,851 housing units at an average density of 1,584.3 per square mile. The racial makeup of the city was 84.44% White, 7.65% Asian / Asian American, 0.26% Native American, 1.01% Black or African American, 0.02% Pacific Islander, 4.64% from other races, 1.97% from two or more races. 14.01% were Hispanic or Latino of any race.

Ireland is an island in the North Atlantic. It is separated from Great Britain to its east by the North Channel, the Irish Sea, St George's Channel. Ireland is the second-largest island of the British Isles, the third-largest in Europe, the twentieth-largest on Earth. Politically, Ireland is divided between the Republic of Ireland, which covers five-sixths of the island, Northern Ireland, part of the United Kingdom. In 2011, the population of Ireland was about 6.6 million, ranking it the second-most populous island in Europe after Great Britain. Just under 4.8 million live in the Republic of Ireland and just over 1.8 million live in Northern Ireland. The island's geography comprises low-lying mountains surrounding a central plain, with several navigable rivers extending inland, its lush vegetation is a product of its mild but changeable climate, free of extremes in temperature. Much of Ireland was woodland until the end of the Middle Ages. Today, woodland makes up about 10% of the island, compared with a European average of over 33%, most of it is non-native conifer plantations.
There are twenty-six extant mammal species native to Ireland. The Irish climate is influenced by the Atlantic Ocean and thus moderate, winters are milder than expected for such a northerly area, although summers are cooler than those in continental Europe. Rainfall and cloud cover are abundant; the earliest evidence of human presence in Ireland is dated at 10,500 BC. Gaelic Ireland had emerged by the 1st century AD; the island was Christianised from the 5th century onward. Following the 12th century Norman invasion, England claimed sovereignty. However, English rule did not extend over the whole island until the 16th–17th century Tudor conquest, which led to colonisation by settlers from Britain. In the 1690s, a system of Protestant English rule was designed to materially disadvantage the Catholic majority and Protestant dissenters, was extended during the 18th century. With the Acts of Union in 1801, Ireland became a part of the United Kingdom. A war of independence in the early 20th century was followed by the partition of the island, creating the Irish Free State, which became sovereign over the following decades, Northern Ireland, which remained a part of the United Kingdom.
Northern Ireland saw much civil unrest from the late 1960s until the 1990s. This subsided following a political agreement in 1998. In 1973 the Republic of Ireland joined the European Economic Community while the United Kingdom, Northern Ireland, as part of it, did the same. Irish culture has had a significant influence on other cultures in the field of literature. Alongside mainstream Western culture, a strong indigenous culture exists, as expressed through Gaelic games, Irish music and the Irish language; the island's culture shares many features with that of Great Britain, including the English language, sports such as association football, horse racing, golf. The names Éire derive from Old Irish Eriu; this in turn comes from the Proto-Celtic *Iveriu, the source of Latin Hibernia. Iveriu derives from a root meaning'fat, prosperous'. During the last glacial period, up until about 10,000 BC, most of Ireland was periodically covered in ice. Sea levels were lower and Ireland, like Great Britain, formed part of continental Europe.
By 16,000 BC, rising sea levels due to ice melting caused Ireland to become separated from Great Britain. Around 6000 BC, Great Britain itself became separated from continental Europe; the earliest evidence of human presence in Ireland is dated at 10,500 BC, demonstrated by a butchered bear bone found in a cave in County Clare. It is not until about 8000 BC, that more sustained occupation of the island has been shown, with evidence for Mesolithic communities around the island; these Mesolithic communities lived as hunter-gatherers across the island until about 4000 BC. Some time before 4000 BC, Neolithic settlers arrived introducing cereal cultivars, domesticated animals such as cattle and sheep, large timber building, stone monuments; the earliest evidence for farming in Ireland or Great Britain is from Co.. Kerry, where a flint knife, cattle bones and a sheep's tooth were carbon-dated to c. 4350 BC. Field systems were developed in different parts of Ireland, including at the Céide Fields, preserved beneath a blanket of peat in present-day Tyrawley.
An extensive field system, arguably the oldest in the world, consisted of small divisions separated by dry-stone walls. The fields were farmed for several centuries between 3500 BC and 3000 BC. Wheat and barley were the principal crops; the Bronze Age – defined by the use of metal – began around 2500 BC, with technology changing people's everyday lives during this period through innovations such as the wheel. According to John T. Koch and others, Ireland in the Late Bronze Age was part of a maritime trading-network culture called the Atlantic Bronze Age that included Britain, western France and Iberia, that this is where Celtic languages developed; this contrasts with the traditional view that their origin lies in mainland Europe with the Hallstatt culture. During the Iron Age, a Celtic language and culture emerged in Ireland. How and when the island became Celtic has been debated for close to a century, with the migrations of the Celts being one of the more enduring themes of archaeological and linguistic studies.

Bangor is a city and community in Gwynedd, northwest Wales. It is the oldest city in Wales, one of the smallest cities in the United Kingdom. In Caernarfonshire, it is a university city with a population of 18,808 at the 2011 census, including around 10,500 students at Bangor University, it is one of only six places classed as a city in Wales, although it is only the 25th-largest urban area by population. At the 2001 census, 46.6% of the non-student resident population spoke Welsh. The origins of the city date back to the founding of a monastic establishment on the site of Bangor Cathedral by the Celtic saint Deiniol in the early 6th century AD. Bangor itself is an old Welsh word for a wattled enclosure, such as the one that surrounded the cathedral site; the present cathedral is a somewhat more recent building and has been extensively modified throughout the centuries. While the building itself is not the oldest, not the biggest, the bishopric of Bangor is one of the oldest in the UK. Another claim to fame is that Bangor has the longest High Street in Wales and the United Kingdom.
Friars School was founded as a free grammar school in 1557, the University College of North Wales was founded in 1884. In 1877, the former HMS Clio became a school ship, moored on the Menai Strait at Bangor, had 260 pupils. Closed after the end of hostilities of World War I, she was sold for scrap and broken up in 1919. During World War II, parts of the BBC evacuated to Bangor during the worst of the Blitz. In June 2012 Bangor was the first city in the UK to impose a city centre wide night time curfew on under-16s; the six-month trial was brought in by Gwynedd Council and North Wales police, but opposed by civil rights groups. Bangor has been unique outside of England in using the title of'city' by ancient prescriptive right, due to its long-standing cathedral. However, city status was conferred on it by the Queen in 1974. By means of various measures, it is one of the smallest cities in the UK. Using 2011 statistics, comparing Bangor to: Population of city council areas in Wales, is third with St Davids and St Asaph City council area size within Wales, is the second smallest city behind St Asaph Urban areas within Wales, is third placed behind St Davids and St Asaph City council area size within the UK, is fourth after the City of London, Wells and St Asaph Urban areas within the UK, is fifth placed Population of city council areas within the UK, is sixth.
Bangor lies on the coast of North Wales near the Menai Strait which separates the island of Anglesey from Gwynedd unitary authority, the town of Menai Bridge lying just over the strait. The combined population of the two amounts to 22,184 people as of the 2011 census. Bangor Mountain lies to the east of the main part of the city, but the large housing estate of Maesgeirchen built as council housing, is to the east of the mountain near Port Penrhyn. Bangor Mountain casts a shadow across the High Street, Glan Adda and Hirael areas, so that from November to March some parts of the High Street in particular receive no direct sunlight. Another ridge rises to the north of the High Street, dividing the city centre from the south shore of the Menai Strait. Bangor has two rivers within its boundaries; the River Adda is a culverted watercourse which only appears above ground at its western extremities near the Faenol estate, whilst the River Cegin enters Port Penrhyn at the eastern edge of the city. Port Penrhyn was an important port in the 19th century, exporting the slates produced at the Penrhyn Quarry.
Bangor railway station is located on the North Wales Coast Line from Chester to Holyhead. The A55 runs to the south of Bangor, providing a route to Holyhead and Chester; the nearest airport with international flights is 83 miles by road. Bangor lies at the western end of the North Wales Path, a 60 miles long-distance coastal walking route to Prestatyn. Bangor is on routes NCR 8 and NCR 85 of the National Cycle Network. Classical music is performed in Bangor, with concerts given in the Powis and Prichard-Jones Halls as part of the university's Music at Bangor concert series; the city is home to Storiel. A new arts centre complex, the replacement for Theatr Gwynedd, was scheduled for completion in the summer of 2014, but the opening was delayed until November 2015. Bangor hosted the National Eisteddfod in 1890, 1902, 1915, 1931, 1940, 1943, 1971 and 2005, as well as an unofficial National Eisteddfod event in 1874. Garth Pier is the second longest pier in Wales, the ninth longest in the British Isles, at 1,500 feet in length.
It was opened in 1893 and was a promenade pier, for the amusement of holiday-makers who could stroll among the pinnacle-roofed kiosks. In 1914 it was struck by a vessel; the damaged section was repaired temporarily by the Royal Engineers, but when in 1922, a permanent repair was contemplated, it was found that the damage was more severe than had been thought. The repairs were made at considerable cost and the pier remained open until 1974 when it was nearly condemned as being in poor condition, it was sold for a nominal price to Arfon Borough Council who proposed to demolish it, but the County Council, encouraged by local support, ensured that it survived by obtaining Grade II Listed building status for it. When it was listed that year, the British Listed Buildings inspector considered it to be "the best in Britain of t
London and Croydon Railway
The London and Croydon Railway was an early railway in England. It opened in 1839 and in February 1846 merged with other railways to form the London Brighton and South Coast Railway; the Surrey Iron Railway had been opened in 1806 between Croydon. However, the Surrey Iron Railway's terminal on the Thames was rather far west and sea-going vessels were discouraged from connecting with it. Edge railways using locomotive traction represented a clear technological advance, marked by the Stockton and Darlington Railway and the Liverpool and Manchester Railway, promoters put forward a scheme to link Croydon an industrial town, with London; the Croydon Canal of 1809 was moribund, it was proposed purchase it and to utilise its course. It was to extend northwards from the Croydon Canal terminal at New Cross, so as to make a junction at Corbetts Lane, in Bermondsey with the London and Greenwich Railway; the engineer Joseph Gibbs surveyed the route. The Company obtained an authorising Act of Parliament on 12 June 1836.
The line was 8 3⁄4 miles long and at the southern end followed the alignment of the Croydon Canal from Anerley to a terminus at Croydon, with a locomotive depot, on the site of the canal basin. This was to be developed to the present-day West Croydon station; the Greenwich company intended that its proposed London Bridge terminus would accommodate trains of several other companies and had acquired land sufficient for the purpose. At this stage the Greenwich line had not yet been opened into London Bridge: this was completed on 1 December 1836; the South Eastern Railway got its authorising Act of Parliament on 21 June 1836 for a line from Dover, joining the London and Croydon line end-on at Croydon, the London and Brighton Railway obtained its Act on 15 June 1837 relying on running over the London and Croydon from Norwood. Over the following two years the point of convergence with the L&CR was varied, but all the lines converged at or before Corbett's Lane Junction. Capacity at London Bridge was going to be an issue, the L&CR took further powers to enlarge its station under construction at London Bridge.
A Parliamentary Select Committee became concerned about the safety of the arrangements, in response the Greenwich Company was given powers to widen its viaduct on the southern side so as to make a four-track viaduct from Corbett's Lane to London Bridge. In its first conception, the line was to follow the bed of the Croydon Canal for much of the route. A jury determined the value of the canal as £ 40,250; when detailed route design was undertaken, it was clear that the meanderings and zigzags made by the canal were unsuitable, that the line needed to be built alongside the general course. The levels around New Cross were difficult, to find the best compromise a 1 in 80 gradient was selected, involving at that time the use of assistant engines due to the steepness. So, a cutting of considerable depth was unavoidable; when the SER's line became authorised, the Croydon company reconsidered the matter, as its line would now be part of a trunk route, it was decided to ease the gradient from New Cross to 1 in 100.
The deeper cuttings required more surface area of land. Stations were to be at New Cross, Dartmouth Arms (named after a nearby hostelry, still extant in 2013, Penge, Jolly Sailor. and the terminus at Croydon. Freight traffic was considered to be impracticable for handling at London Bridge, the London freight terminal point was built at New Cross. There was an engine shed at New Cross; the consultant engineer was William Cubitt. The line proved to be expensive to build, costing £615,000 rather than the estimated £180,000, due to large cuttings at New Cross and Forest Hill; the only severe gradient was 1:100 for 2.75 miles from New Cross to Forest Hill. In addition to the viaduct where it joined the L&GR, there were 18 bridges, three level road crossings, each attended by a "policeman"; the track was laid to standard 4 ft 8 1⁄2 in gauge, although during the construction the directors were undecided and ordered extra-long 9 ft sleepers with a view to conversion to 7 ft broad gauge, which never happened.
The line used "Vignoles" flat bottomed rail, lower than modern rail. These were mounted on longitudinal timbers with cross sleepers. A new station was built at London Bridge for Croydon trains, on the north side of the L&GR one, with track shared as far as Corbetts Lane; the line opened on 5 June 1839 There were six intermediate stations, at New Cross, Dartmout
Poland the Republic of Poland, is a country located in Central Europe. It is divided into 16 administrative subdivisions, covering an area of 312,696 square kilometres, has a temperate seasonal climate. With a population of 38.5 million people, Poland is the sixth most populous member state of the European Union. Poland's capital and largest metropolis is Warsaw. Other major cities include Kraków, Łódź, Wrocław, Poznań, Gdańsk, Szczecin. Poland is bordered by the Baltic Sea, Russia's Kaliningrad Oblast and Lithuania to the north and Ukraine to the east and Czech Republic, to the south, Germany to the west; the establishment of the Polish state can be traced back to AD 966, when Mieszko I, ruler of the realm coextensive with the territory of present-day Poland, converted to Christianity. The Kingdom of Poland was founded in 1025, in 1569 it cemented its longstanding political association with the Grand Duchy of Lithuania by signing the Union of Lublin; this union formed the Polish–Lithuanian Commonwealth, one of the largest and most populous countries of 16th and 17th century Europe, with a uniquely liberal political system which adopted Europe's first written national constitution, the Constitution of 3 May 1791.
More than a century after the Partitions of Poland at the end of the 18th century, Poland regained its independence in 1918 with the Treaty of Versailles. In September 1939, World War II started with the invasion of Poland by Germany, followed by the Soviet Union invading Poland in accordance with the Molotov–Ribbentrop Pact. More than six million Polish citizens, including 90% of the country's Jews, perished in the war. In 1947, the Polish People's Republic was established as a satellite state under Soviet influence. In the aftermath of the Revolutions of 1989, most notably through the emergence of the Solidarity movement, Poland reestablished itself as a presidential democratic republic. Poland is regional power, it has the fifth largest economy by GDP in the European Union and one of the most dynamic economies in the world achieving a high rank on the Human Development Index. Additionally, the Polish Stock Exchange in Warsaw is the largest and most important in Central Europe. Poland is a developed country, which maintains a high-income economy along with high standards of living, life quality, safety and economic freedom.
Having a developed school educational system, the country provides free university education, state-funded social security, a universal health care system for all citizens. Poland has 15 UNESCO World Heritage Sites. Poland is a member state of the European Union, the Schengen Area, the United Nations, NATO, the OECD, the Three Seas Initiative, the Visegrád Group; the origin of the name "Poland" derives from the West Slavic tribe of Polans that inhabited the Warta river basin of the historic Greater Poland region starting in the 6th century. The origin of the name "Polanie" itself derives from the early Slavic word "pole". In some languages, such as Hungarian, Lithuanian and Turkish, the exonym for Poland is Lechites, which derives from the name of a semi-legendary ruler of Polans, Lech I. Early Bronze Age in Poland begun around 2400 BC, while the Iron Age commenced in 750 BC. During this time, the Lusatian culture, spanning both the Bronze and Iron Ages, became prominent; the most famous archaeological find from the prehistory and protohistory of Poland is the Biskupin fortified settlement, dating from the Lusatian culture of the early Iron Age, around 700 BC.
Throughout the Antiquity period, many distinct ancient ethnic groups populated the regions of what is now Poland in an era that dates from about 400 BC to 500 AD. These groups are identified as Celtic, Slavic and Germanic tribes. Recent archeological findings in the Kujawy region, confirmed the presence of the Roman Legions on the territory of Poland; these were most expeditionary missions sent out to protect the amber trade. The exact time and routes of the original migration and settlement of Slavic peoples lacks written records and can only be defined as fragmented; the Slavic tribes who would form Poland migrated to these areas in the second half of the 5th century AD. Up until the creation of Mieszko's state and his subsequent conversion to Christianity in 966 AD, the main religion of Slavic tribes that inhabited the geographical area of present-day Poland was Slavic paganism. With the Baptism of Poland the Polish rulers accepted Christianity and the religious authority of the Roman Church.
However, the transition from paganism was not a smooth and instantaneous process for the rest of the population as evident from the pagan reaction of the 1030s. Poland began to form into a recognizable unitary and territorial entity around the middle of the 10th century under the Piast dynasty. Poland's first documented ruler, Mieszko I, accepted Christianity with the Baptism of Poland in 966, as the new official religion of his subjects; the bulk of the population converted in the course of the next few centuries. In 1000, Boleslaw the Brave, continuing the policy of his father Mieszko, held a Congress of Gniezno and created the metropolis of Gniezno and the dioceses of Kraków, Kołobrzeg, Wrocław. However, the pagan unrest led to the transfer of the capital to Kraków in 1038 by Casimir I the Restorer. In 1109, Prince Bolesław III Wrymouth defeated the King of Germany Henry V at the Battle of Hundsfeld, stopping the Ge
Morse code is a character encoding scheme used in telecommunication that encodes text characters as standardized sequences of two different signal durations called dots and dashes or dits and dahs. Morse code is named for Samuel F. B. Morse, an inventor of the telegraph; the International Morse Code encodes the 26 English letters A through Z, some non-English letters, the Arabic numerals and a small set of punctuation and procedural signals. There is no distinction between lower case letters; each Morse code symbol is formed by a sequence of dashes. The dot duration is the basic unit of time measurement in Morse code transmission; the duration of a dash is three times the duration of a dot. Each dot or dash within a character is followed by period of signal absence, called a space, equal to the dot duration; the letters of a word are separated by a space of duration equal to three dots, the words are separated by a space equal to seven dots. To increase the efficiency of encoding, Morse code was designed so that the length of each symbol is inverse to the frequency of occurrence in text of the English language character that it represents.
Thus the most common letter in English, the letter "E", has the shortest code: a single dot. Because the Morse code elements are specified by proportion rather than specific time durations, the code is transmitted at the highest rate that the receiver is capable of decoding; the Morse code transmission rate is specified in groups per minute referred to as words per minute. Morse code is transmitted by on-off keying of an information carrying medium such as electric current, radio waves, visible light or sound waves; the current or wave is present during time period of the dot or dash and absent during the time between dots and dashes. Morse code can be memorized, Morse code signalling in a form perceptible to the human senses, such as sound waves or visible light, can be directly interpreted by persons trained in the skill; because many non-English natural languages use other than the 26 Roman letters, Morse alphabets have been developed for those languages. In an emergency, Morse code can be generated by improvised methods such as turning a light on and off, tapping on an object or sounding a horn or whistle, making it one of the simplest and most versatile methods of telecommunication.
The most common distress signal is SOS – three dots, three dashes, three dots – internationally recognized by treaty. Early in the nineteenth century, European experimenters made progress with electrical signaling systems, using a variety of techniques including static electricity and electricity from Voltaic piles producing electrochemical and electromagnetic changes; these numerous ingenious experimental designs were precursors to practical telegraphic applications. Following the discovery of electromagnetism by Hans Christian Ørsted in 1820 and the invention of the electromagnet by William Sturgeon in 1824, there were developments in electromagnetic telegraphy in Europe and America. Pulses of electric current were sent along wires to control an electromagnet in the receiving instrument. Many of the earliest telegraph systems used a single-needle system which gave a simple and robust instrument. However, it was slow, as the receiving operator had to alternate between looking at the needle and writing down the message.
In Morse code, a deflection of the needle to the left corresponded to a dot and a deflection to the right to a dash. By making the two clicks sound different with one ivory and one metal stop, the single needle device became an audible instrument, which led in turn to the Double Plate Sounder System; the American artist Samuel F. B. Morse, the American physicist Joseph Henry, Alfred Vail developed an electrical telegraph system, it needed a method to transmit natural language using only electrical pulses and the silence between them. Around 1837, therefore, developed an early forerunner to the modern International Morse code. William Cooke and Charles Wheatstone in England developed an electrical telegraph that used electromagnets in its receivers, they obtained an English patent in June 1837 and demonstrated it on the London and Birmingham Railway, making it the first commercial telegraph. Carl Friedrich Gauss and Wilhelm Eduard Weber as well as Carl August von Steinheil used codes with varying word lengths for their telegraphs.
In 1841, Cooke and Wheatstone built a telegraph that printed the letters from a wheel of typefaces struck by a hammer. The Morse system for telegraphy, first used in about 1844, was designed to make indentations on a paper tape when electric currents were received. Morse's original telegraph receiver used a mechanical clockwork to move a paper tape; when an electrical current was received, an electromagnet engaged an armature that pushed a stylus onto the moving paper tape, making an indentation on the tape. When the current was interrupted, a spring retracted the stylus and that portion of the moving tape remained unmarked. Morse code was developed so that operators could translate the indentations marked on the paper tape into text messages. In his earliest code, Morse had planned to transmit only numerals and to use a codebook to look up each word according to the number, sent. However, the code was soon expanded by Alfred Vail in 1840 to include letters and special characters so it could be used more generally.
Vail estimated the frequency of use of letters in the English language by counting the movable type he found in the type-cases of a local newspaper in Morristown. The shorter marks were called "dots" and the longer ones "dashes", the letters most used were assigned the shorter sequences of dots and dashes; this code was used since 1844 and became known as Morse lan
