Tatra K5
The Tatra K5AR was an articulated tramcar built by ČKD Tatra. It was unusual in that it was one of the few tramcars built by ČKD Tatra to be exported outside of Warsaw Pact, and was designed specifically for the city of Cairo, Egypt Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Medit ..., which took 200 examples. The K5AR was bi-directional and was fitted with 3 doors in each car, and its electrical equipment was designed to withstand the sub-tropical climate of Egypt. After less than a decade in service, the vast majority of these tramcars were in very poor condition owing to over-loading and poor maintenance, and only a small handful remained in service until the mid-1980s.

ČKD Tatra
ČKD (Českomoravská Kolben-Daněk) () was one of the largest engineering companies in the former Czechoslovakia and today's Czech Republic. It is famous for the Tatra T3, a tramcar that sold 13,991 units worldwide. History ČKD was formed in 1927 from the merger of two smaller companies, Českomoravská-Kolben (founded 1896, produced machinery for hydro dams) and Breitfeld-Daněk (founded 1854, produced machinery for mines and food industry). From 1927 until 1929 ČKD's products included a motorcycle designed by Jaroslav František Koch. It was an advanced four-stroke single-cylinder unit construction double overhead camshaft design of 500cc. It was sold under the marque BD, thus perpetuating the Breitfeld-Daněk identity. In 1929 ČKD sold its motorcycle business to Praga Hostivař, which re-branded the motorcycles under the Praga marque. It was one of the main suppliers to the Czechoslovak state of military vehicles during the 1930s. During the German occupation of Czech ...

Tatra KT4
Tatra KT4 is the name of a four-axle type articulated tramcar developed by the Czech firm ČKD Tatra. The first pre-production vehicles entered service in Potsdam in 1975, with the first production vehicles in 1977. A total of 1,747 units were built, with initial deliveries to East Germany (DDR) and later to the USSR and SFR Yugoslavia. KT4 variants were built for both standard gauge and metre gauge tramways. Production of the KT4 tramcar was halted in 1991 due to worldwide economic and political changes at the time. Production was briefly resumed in 1997 to construct the last 20 units for Belgrade, Serbia. Since the start of the 1990s, many of the earliest production tramcars have gone through extensive refurbishment and rebuilding, including the replacement of folding doors and the installation of low-floor center sections. The design of the tram, being without a bogie over the joint necessitates a scissor joint connecting both bogies such that the center of mass does not sh ...

Articulated
An articulated vehicle is a vehicle which has a permanent or semi-permanent pivot joint in its construction, allowing it to turn more sharply. There are many kinds, from heavy equipment to buses, trams and trains. Steam locomotives were sometimes articulated so driving wheels could pivot around corners. In a broader sense, any vehicle towing a trailer (including a semi-trailer) could be described as articulated (which comes from the Latin ''articulus'', "small joint"). In the UK, an ''articulated lorry'' is the combination of a tractor and a trailer, abbreviated to "artic". In the US, it is called a semi-trailer truck, tractor-trailer or semi-truck, and is not necessarily considered articulated. Types Buses Buses are articulated to allow for a much longer bus which can still navigate within the turning radius of a normal bus. Trucks In the UK, tractor unit and trailer combinations are referred to as Articulated lorries, or "artics". semi-trailertruck, also known as a ...

Tram
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses". In the Unit ...

Warsaw Pact
The Warsaw Pact (WP) or Treaty of Warsaw, formally the Treaty of Friendship, Cooperation and Mutual Assistance, was a collective defense treaty signed in Warsaw, Poland, between the Soviet Union and seven other Eastern Bloc socialist republics of Central and Eastern Europe in May 1955, during the Cold War. The term "Warsaw Pact" commonly refers to both the treaty itself and its resultant defensive alliance, the Warsaw Treaty Organization (WTO). The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (Comecon), the regional economic organization for the socialist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into the North Atlantic Treaty Organization (NATO)"In reaction to West Germany's NATO accession, the Soviet Union and its Eastern European client states formed the Warsaw Pact in 1955."

Cairo
Cairo ( ; ar, القاهرة, al-Qāhirah, ) is the capital of Egypt and its largest city, home to 10 million people. It is also part of the largest urban agglomeration in Africa, the Arab world and the Middle East: The Greater Cairo metropolitan area, with a population of 21.9 million, is the 12th-largest in the world by population. Cairo is associated with ancient Egypt, as the Giza pyramid complex and the ancient cities of Memphis and Heliopolis are located in its geographical area. Located near the Nile Delta, the city first developed as Fustat, a settlement founded after the Muslim conquest of Egypt in 640 next to an existing ancient Roman fortress, Babylon. Under the Fatimid dynasty a new city, ''al-Qāhirah'', was founded nearby in 969. It later superseded Fustat as the main urban centre during the Ayyubid and Mamluk periods (12th–16th centuries). Cairo has long been a centre of the region's political and cultural life, and is titled "the city of a thousand m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sub-tropical
The subtropical zones or subtropics are geographical and climate zones to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical (Koppen climate Cfa), where rainfall is often concentrated in the warmest months, for example Southeast China and the Southeastern United States, and dry summer or Mediterranean climate (Koppen climate Csa/Csb), where seasonal rainfall is concentrated in the cooler months, such as the Mediterranean Basin or Southern California. Subtropical climates can also occur at high elevations within the tropics, such as in the southern end of the Mexican Plateau and in Da Lat of the Vietnamese Central Highlands.
