Attractions Caspian Sea The Caspian Sea is the world's largest inland body of water, variously classed as the world's largest lake or a full-fledged sea. It is an endorheic basin (a basin without outflows) located between Europe and Asia, to the east of the Caucasus Mountains and to the west of the broad steppe of Central Asia.

Caspian Sea
The Caspian Sea is the world's largest inland body of water, often described as the world's largest lake or a full-fledged sea. An endorheic basin, it lies between Europe and Asia; east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau of Western Asia. It covers a surface area of (excluding the highly saline lagoon of Garabogazköl to its east) and a volume of . It has a salinity of approximately 1.2% (12 g/L), about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast. The sea stretches nearly from north to south, with an average width of . Its gross coverage is and the surface is about below sea level. Its main freshwater inflow, Europe's longest river, the Volga, enters at the shallow north end. Two deep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steppe
In physical geography, a steppe () is an ecoregion characterized by grassland plains without trees apart from those near rivers and lakes. Steppe biomes may include: * the montane grasslands and shrublands biome * the temperate grasslands, savannas and shrublands biome A steppe may be semi-arid or covered with grass or with shrubs or with both, depending on the season and latitude. The term " steppe climate" denotes the climate encountered in regions too dry to support a forest but not dry enough to be a desert. Steppe soils are typically of the chernozem type. Steppes are usually characterized by a semi-arid or continental climate. Extremes can be recorded in the summer of up to and in winter, . Besides this major seasonal difference, fluctuations between day and night are also very great. In both the highlands of Mongolia and northern Nevada, can be reached during the day with sub-freezing readings at night. Mid-latitude steppes feature hot summers and cold wint ...

Track Gauge Changing Facility
A variable gauge system allows railway vehicles in a train to travel across a break of gauge between two railway networks with different track gauges. For through operation, a train must be equipped with special bogies holding variable gauge wheelsets containing a variable gauge axle (VGA). The gauge is altered by driving the train through a gauge changer or gauge changing facility. In effect, the track widens or narrows. As the train passes through the gauge changer, the wheels are unlocked, are moved closer together, or further apart, and are then re-locked. Installed variable gauge systems exist within the internal network of Spain, and are installed on international links between Spain/France (Spanish train), Sweden/Finland (Swedish train), Poland/ Lithuania (Polish train) and Poland/Ukraine (Polish train). A system for changing gauge without the need to stop is in widespread use for passenger traffic in Spain, for services run on a mix of dedicated high-speed lines (using ...

SUW 2000
SUW 2000 is a Polish variable gauge system that allows trains to cross a break of gauge. It is interoperable with the German Rafil Type V system (built by the Radsatzfabrik Ilsenburg). History The SUW 2000 system was designed by Ryszard Suwalski. Suwalski, of PKP Cargo, developed the system between 1990 and 1992. Prototype wheelsets, bogies for passenger carriages and goods wagons, and gauge changer were produced in 1993. The wheelsets were manufactured by ZNTK Poznań. In October 2000 first regular passenger and freight trains started running between Poland and Lithuania. In June 2003 regular passenger trains started running between Poland and Ukraine. In 2008 SUW 2000 II, a development of the original SUW 2000, was presented. It introduced new bogie, improved gauge changer that is expected to last 20% longer, and electronic system checking and registering regauging and wheelset locking. In 2019 PKP acquired documentation and rights to the SUW 2000 patents and technology. The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogie Exchange
Bogie exchange is a system for operating railway wagons on two or more gauges to overcome difference in the track gauge. To perform a bogie exchange, a car is converted from one gauge to another by removing the bogies or trucks (the chassis containing the wheels and axles of the car), and installing a new bogie with differently spaced wheels. It is generally limited to wagons and carriages, though the bogies on diesel locomotives can be exchanged if enough time is available. Wagons and carriages Bogie wagons can have their gauge changed by lifting them off one set of bogies and putting them back down again on another set of bogies. The pin that centres the bogies and the hoses and fittings for the brakes must be compatible. A generous supply of bogies of each gauge is needed to accommodate the ebb and flow of traffic. The bogies and wagons also need to have standardized hooks, etc., where they may be efficiently lifted. The two wheel sets on four-wheel wagons can be change ...

Standard Gauge
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broad Gauge
A broad-gauge railway is a railway with a track gauge (the distance between the rails) broader than the used by standard-gauge railways. Broad gauge of , commonly known as Russian gauge, is the dominant track gauge in former Soviet Union (CIS states, Baltic states, Georgia and Ukraine), Mongolia and Finland. Broad gauge of , commonly known as Irish Gauge, is the dominant track gauge in Ireland, and the Australian states of Victoria and Adelaide. Broad gauge of , commonly known as Iberian gauge, is the dominant track gauge in Spain and Portugal. Broad gauge of , commonly known as Indian gauge, is the dominant track gauge in India, Pakistan, Bangladesh, Sri Lanka, Argentina, Chile, and on BART (Bay Area Rapid Transit) in the San Francisco Bay Area. This is the widest gauge in common use anywhere in the world. It is possible for trains on both Iberian gauge and Indian gauge to travel on each other's tracks with no modifications in the vast majority of cases. History In Gr ...

Seawater
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately of dissolved salts (predominantly sodium () and chloride () ions). The average density at the surface is 1.025 kg/L. Seawater is denser than both fresh water and pure water (density 1.0 kg/L at ) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about . The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was . Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measurement ...
