Virginia And Truckee Railway Motor Car 22
Virginia and Truckee Railway Motor Car 22, also called McKeen Motor Car 70, is a gasoline-powered railcar at the Nevada State Railroad Museum in Carson City in the U.S. state of Nevada. It was built for the Virginia and Truckee Railroad in 1910 by the McKeen Motor Car Company. Motor Car 22 was operated by the Virginia and Truckee until 1945, when it was sold off and became a diner until 1955. It eventually became the office and storage space for a plumbing business before it was donated to the Nevada State Railroad Museum in 1995. After a thorough study, the Museum undertook a restoration of the McKeen car in 1997. The restored motor car was unveiled in 2010, a century after it was originally delivered to the Virginia and Truckee. Motor Car 22 was listed on the National Register of Historic Places in 2005, and designated a National Historic Landmark in 2012. It is one of a few surviving McKeen railcars, and the only one that is operational. Design Virginia and Truckee Railway Mot ...

McKeen Motor Car Company
The McKeen Motor Car Company of Omaha, Nebraska, was a builder of internal combustion-engined railroad motor cars (railcars), constructing 152 between 1905 and 1917. Founded by William McKeen, the Union Pacific Railroad's Superintendent of Motive Power and Machinery, the company was essentially an offshoot of the Union Pacific and the first cars were constructed by the UP before McKeen leased shop space in the UP's Omaha Shops in Omaha, Nebraska. The UP had asked him to develop a way of running small passenger trains more economically and McKeen produced a design that was ahead of its time. Unfortunately, internal combustion engine technology was not and the McKeen cars never found a truly reliable powerplant. The vast majority of the cars produced were for E. H. Harriman's empire of lines (Union Pacific, Southern Pacific and others). Harriman's death in 1909 lost the company its major sponsor and investor and Harriman's successors were less enthusiastic about the McKeen cars. ...

Passenger Rail Car
A passenger railroad car or passenger car (United States), also called a passenger carriage, passenger coach (United Kingdom and International Union of Railways), or passenger bogie (India) is a railroad car that is designed to carry passengers. The term ''passenger car'' can also be associated with a sleeping car, a baggage car, a dining car, railway post office and prisoner transport cars. The first passenger cars were built in the early 1800s with the advent of the first railroads, and were small and little more than converted freight cars. Early passenger cars were constructed from wood; in the 1900s construction shifted to steel and later aluminum for improved strength. Passenger cars have increased greatly in size from their earliest versions, with modern bi-level passenger cars capable of carrying over 100 passengers. Amenities for passengers have also improved over time, with developments such as lighting, heating, and air conditioning added for improved passenger comf ...

Acetylene
Acetylene (systematic name: ethyne) is the chemical compound with the formula and structure . It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.Compressed Gas Association (1995Material Safety and Data Sheet – Acetylene As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond. The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°. Discovery Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was an accidental discovery while attempting to isolate potassium metal. By heating potassium carbonate with carbon at very high temperatures, he produced a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feasibility Study
A feasibility study is an assessment of the practicality of a project or system. A feasibility study aims to objectively and rationally uncover the strengths and weaknesses of an existing business or proposed venture, opportunities and threats present in the natural environment, the resources required to carry through, and ultimately the prospects for success.Justis, R. T. & Kreigsmann, B. (1979). The feasibility study as a tool for venture analysis. ''Business Journal of Small Business Management'' 17 (1) 35-42. In its simplest terms, the two criteria to judge feasibility are cost required and value to be attained. A well-designed feasibility study should provide a historical background of the business or project, a description of the product or service, accounting statements, details of the operations and management, marketing research and policies, financial data, legal requirements and tax obligations. Generally, feasibility studies precede technical development and project ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine 22, 3
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in ...

Plumbing
Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids. Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications. The word derives from the Latin for lead, ''plumbum'', as the first effective pipes used in the Roman era were lead pipes. In the developed world, plumbing infrastructure is critical to public health and sanitation. Boilermakers and pipefitters are not plumbers although they work with piping as part of their trade and their work can include some plumbing. History Plumbing originated during ancient civilizations, as they developed public baths and needed to provide potable water and wastewater removal for larger numbers of people. The Mesopotamians introduced the world to clay sewer pipes around 4000 BCE, with the earliest examples found i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Express Agency
Railway Express Agency (REA), founded as the American Railway Express Agency and later renamed the American Railway Express Inc., was a national package delivery service that operated in the United States from 1918 to 1975. REA arranged transport and delivery via existing railroad infrastructure, much as today's UPS or DHL companies use roads and air transport. It was created through the forced consolidation of existing services into a national near-monopoly to ensure the rapid and safe movement of parcels, money, and goods during World War I. REA ceased operations in 1975, when its business model ceased to be viable. Early history Express delivery in the early 19th century was almost all by horse, whether by stagecoach or riders. The first parcel express agency in the United States is generally considered to have been started by William Frederick Harnden (1812–1845), who in 1839 began regular trips between New York City and Boston, Massachusetts, as a courier transpor ...

Railway Post Office
In Canada and the United States, a railway post office, commonly abbreviated as RPO, was a railroad car that was normally operated in passenger service as a means to sort mail en route, in order to speed delivery. The RPO was staffed by highly trained Railway Mail Service postal clerks, and was off-limits to the passengers on the train. In the UK and Ireland, the equivalent term was travelling post office (TPO). From the middle of the 19th century, many American railroads earned substantial revenues through contracts with the U.S. Post Office Department (USPOD) to carry mail aboard high-speed passenger trains; and the Railway Mail Service enforced various standardized designs on RPOs. In fact, a number of companies maintained passenger routes where the financial losses from moving people were more than offset by transporting the mail. History The world's first official carriage of mail by rail was by the United Kingdom's General Post Office in November 1830, using adapted rail ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Minden, Nevada
Minden is a census-designated place (CDP) in Douglas County, Nevada, United States. The population was 3,001 at the 2010 census. It is the county seat of Douglas County and is adjacent to the town of Gardnerville. The Douglas campus of the Western Nevada College is located in Minden. History It was founded in 1906 by Heinrich Friedrich Dangberg Jr., who named it after the town of Minden, in the German state of North Rhine-Westphalia, which was near his father's birthplace. A large share of the first settlers were Germans. Minden was founded on company land of the Dangberg Home Ranch and Dangberg commissioned most of the town's early buildings. Minden has had a post office since 1906. Use of sundown siren and sundown town status Minden sounds a " sundown siren" at 6pm almost every evening since 1917, originally signifying that members of the Washoe Indian tribe were required to leave town by 6:30pm or face jail or fine. Douglas County fully repealed its sundown ordina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
