Atomic Train
''Atomic Train'' is a 1999 American made-for-television disaster-action- thriller miniseries about an accidental nuclear explosion destroying the city of Denver, Colorado. It was originally broadcast on NBC in two parts on May 16 and 17, 1999. Plot In Stillwater, Utah, Bradshaw Disposal Services is transporting a Russian nuclear bomb. An employee, John Henry Bradshaw, decides to save money by concealing the bomb on a freight train which is also loaded with hazardous and flammable chemicals, bound for Denver. The train loses all brakes when its air hoses disconnect, becoming a high-speed runaway. The lead engineer, Wally Phister, crushes his hand as he unsuccessfully attempts to re-connect the hoses before they reach for the portable derailer set up by the Denver Railway Control at Silver Gorge. John Seger, a National Transportation Safety Board investigator, is notified of the crisis and boards on the chasing locomotive via a helicopter piloted by Ray, another engineer. Ed ...

Disaster Film
A disaster film or disaster movie is a film genre that has an impending or ongoing disaster as its subject and primary plot device. Such disasters may include natural disasters, accidents, offensive (military), military/terrorism, terrorist attacks or global catastrophes such as a pandemic. A subgenre of Action film, action films, these films usually feature some degree of build-up, the disaster itself, and sometimes the aftermath, usually from the point of view of specific individual characters or their families or portraying the survival tactics of different people. These films often feature large casts of actors and multiple plot lines, focusing on the characters' attempts to avert, escape or cope with the disaster and its aftermath. The genre came to particular prominence during the 1970s with the release of high-profile films such as ''Airport (1970 film), Airport'' (1970), followed in quick succession by ''The Poseidon Adventure (1972 film), The Poseidon Adventure'' (1972) ...

Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear weapon), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. Nuclear bombs have had yields between 10 tons (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). Yields in the low kilotons can devastate cities. A thermonuclear weapon weighing as little as can release energy equal to more than 1.2 megatons of TNT (5.0 PJ). Apart from the blast, effects of nuclear weapons include firestorms, extreme heat and ionizing radiation, radioactive nuclear fallout, an electromagnetic pulse, and a radar blackout. The first nuclear weapons were developed by the Allied Manhattan Project during World War II. Their production continues to require a large scientific and industrial complex, pr ...

Nuclear Explosion
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction. The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device. Nuclear explosions are used in nuclear weapons and nuclear testing. Nuclear explosions are extremely destructive compared to conventional (chemical) explosives, because of the vastly greater energy density of nuclear fuel compared to chemical explosives. They are often associated with mushroom clouds, since any large atmospheric explosion can create such a cloud. Nuclear explosions produce high levels of ionizing radiation and Nuclear fallout, radioactive debris that is harmful to humans and can cause moderate to severe skin burns, eye damage, radiation sickness, radiation-induced cancer and possible ...

Sodium
Sodium is a chemical element; it has Symbol (chemistry), symbol Na (from Neo-Latin ) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 element, group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not occur in nature and must be prepared from compounds. Sodium is the Abundance of elements in Earth's crust, sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been Leaching (chemistry), leached by the action of water from the Earth, Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide (lye) is used in Soap, soap manufac ...

Boxcar
A boxcar is the North American (Association of American Railroads, AAR) and South Australian Railways term for a Railroad car#Freight cars, railroad car that is enclosed and generally used to carry freight. The boxcar, while not the simplest Railroad car#Freight cars, freight car design, is considered one of the most versatile since it can carry most loads. Boxcars have side sliding doors of varying size and operation, and some include end doors and adjustable Bulkhead (partition), bulkheads to load very large items. Similar covered freight cars outside North America are covered goods wagons and, depending on the region, are called ''goods van'' (United Kingdom, UK and Australia), ''covered wagon'' (International Union of Railways, UIC and UK) or simply ''van'' (UIC, UK and Australia). Use Boxcars can carry most kinds of freight. Originally they were hand-loaded, but in more recent years mechanical assistance such as forklifts have been used to load and empty them fas ...

Nuclear Emergency Support Team
The Nuclear Emergency Support Team (NEST), formerly known as the Nuclear Emergency Search Team, is a team of scientists, technicians, and engineers operating under the United States Department of Energy's National Nuclear Security Administration (DOE/NNSA). NEST is the umbrella designation that encompasses all DOE/NNSA radiological and nuclear emergency response functions; some of which date back more than 60 years. NEST's responsibilities include both national security missions, particularly; countering weapons of mass destruction (WMD) and public health and safety, including responses to nuclear reactor accidents. NEST's task is to be "prepared to respond immediately to any type of radiological accident or incident anywhere in the world". History Concerns over scenarios involving nuclear accidents or incidents on American soil reach back decades. As early as the 1960s, officials were concerned that a nuclear weapon might be smuggled into the country or that an airplane carry ...

National Transportation Safety Board
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has three regional offices, located in Anchorage, Alaska; Aurora, Colorado; and Federal Way, Washington. The agency also operated a national training center at its Ashburn facility. History The origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. Before the NTSB, the Federal Aviation Administration's (FAA; at the time the CAA/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derail
A derail or derailer is a device used to prevent fouling (blocking or compromising) of a rail track (or collision with anything present on the track, such as a person, or a train) by unauthorized movements of trains or unattended rolling stock. The device works by derailing the equipment as it rolls over or through it. Although accidental derailment is damaging to equipment and track, and requires considerable time and expense to remedy, derails are used in situations where there is a risk of greater damage to equipment, injury or death if equipment is allowed to proceed past the derail point. Applications Derails may be applied: *where sidings meet main lines or other through tracks *at junctions or other crossings to protect the interlocking against unauthorized movement *temporarily at an area where crews are working on a rail line *approaching a drawbridge, dead end, or similar hazard. Design There are four basic forms of derail. Wedge The most common form is a w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Runaway Train
A runaway train is a type of railroad incident in which unattended rolling stock is accidentally allowed to roll onto the main line, a moving train loses enough braking power to be unable to stop in safety, or a train operates at unsafe speeds due to loss of operator control. If the uncontrolled rolling stock derails or hits another train, it will result in a train wreck. A deadman's control, if the brakes are working, can prevent unattended rolling stock from moving. A railway air brake can fail if valves on the pipe between each wagon are accidentally closed; the 1953 Pennsylvania Railroad train wreck and the 1988 Gare de Lyon train accident were results of a valve accidentally closed by the crew, reducing braking power. A parked train or cut off cars may also run away if not properly tied down with a sufficient number of hand brakes. Incidents Accidents and incidents involving defective or improperly-set railway brakes include: See also * Dark territory * Positive t ...

Rail Freight Transport
Rail freight transport is the use of railways and trains to transport cargo as opposed to human passengers. A freight train, cargo train, or goods train is a group of freight cars (US) or goods wagons (International Union of Railways) hauled by one or more locomotives on a railway, transporting cargo all or some of the way between the shipper and the intended destination as part of the logistics chain. Trains may haul bulk material handling, bulk material, intermodal containers, general freight or specialized freight in purpose-designed cars. Rail freight practices and economics vary by country and region. When considered in terms of ton-miles or tonne-kilometers hauled, Energy efficiency in transport#Trains, energy efficiency can be greater with rail transportation than with other means. Maximum economies are typically realized with bulk commodities (e.g., coal), especially when hauled over long distances. Moving goods by rail often involves transshipment costs, particularly ...

Contraband
Contraband (from Medieval French ''contrebande'' "smuggling") is any item that, relating to its nature, is illegal to be possessed or sold. It comprises goods that by their nature are considered too dangerous or offensive in the eyes of the legislator—termed contraband ''in se''—and forbidden. Derivative contraband consists of goods that may normally be owned, but are liable to be seized because they were used in committing an unlawful act and hence begot illegally, e.g. smuggling goods; stolen goods – knowingly participating in their trade is an offense in itself, called Fence (criminal), fencing. Law of armed conflict In international law, contraband means goods that are ultimately destined for territory under the control of the enemy and may be susceptible to use in armed conflict. Traditionally, contraband is classified into two categories, absolute contraband and conditional contraband. The former category includes arms, munitions, and various materials, such a ...
