Gilpin Tramway
The Gilpin Railroad, earlier the Gilpin Tramway Company, was a narrow gauge railway in Gilpin County, Colorado, in operation from 1887 to 1917. Gold extraction In April 1859, John H. Gregory discovered alluvial gold in Clear Creek, near Golden, Colorado. The gold was concentrated in the north branch of Clear Creek, in what is now called Gregory Gulch above Blackhawk.Ferrell (1970) p.9 News of the discovery spread, and by September, 900 prospectors had arrived, living in log shanties and tents. By the summer of 1860, sixty ore mills and thirty arrastras were in operation and the population had risen to 15,000. Mining camps, including Black Hawk, Central City, Nevadaville, Russell Gulch and Apex were formed. But by the mid-1860s, the easily-accessible alluvial gold deposit had been exhausted. A smelter was set up in Black Hawk in 1865, to allow gold to be extracted from hard rock ore. In 1870, the narrow gauge Colorado Central Railroad was formed to provide transpor ...

Radius
In classical geometry, a radius (: radii or radiuses) of a circle or sphere is any of the line segments from its Centre (geometry), center to its perimeter, and in more modern usage, it is also their length. The radius of a regular polygon is the line segment or distance from its center to any of its Vertex (geometry), vertices. The name comes from the Latin ''radius'', meaning ray but also the spoke of a chariot wheel.Definition of Radius at dictionary.reference.com. Accessed on 2009-08-08. The typical abbreviation and mathematical symbol for radius is ''R'' or ''r''. By extension, the diameter ''D'' is defined as twice the radius:Definition of radius at mathwords.com. ...

Caboose
A caboose is a crewed North American railroad car coupled at the end of a freight train. Cabooses provide shelter for crew at the end of a train, who were formerly required in switching and shunting; as well as in keeping a lookout for load shifting, damage to equipment and cargo, and overheating axles. Originally flatcars fitted with cabins or modified box cars, they later became purpose-built, with bay windows above or to the sides of the car to allow crew to observe the train. The caboose also served as the conductor's office, and on long routes, included sleeping accommodations and cooking facilities. A similar railroad car, the brake van, was used on British and Commonwealth railways outside North America (the role has since been replaced by the crew car in Australia). On trains not fitted with continuous brakes, brake vans provided a supplementary braking system, and they helped keep chain couplings taut. Cabooses were used on every freight train in the United ...

Tank Car
A tank car (International Union of Railways (UIC): tank wagon) or tanker is a type of railroad car (UIC: railway car) or rolling stock designed to transport liquid and gaseous commodity, commodities. History Timeline The following major events occurred in the years noted: *1865: Flatcars with banded Plank (wood), wooden planks or decking mounted on top are employed for the first time to transport crude oil from the fields of Pennsylvania during the Pennsylvanian oil rush. Laurence Myers of Philadelphia invented the ''Rotary Oil Car'', as he named it. It was an improvement on a patent from 1851 of a freight car for transporting coal. The new invention patented on July 18, 1865, was for the transportation of crude oil and petroleum. It was the first appearance of an oil tank on a railroad flatcar. Three books mention his invention. *1869: Wrought iron tanks, with an approximate capacity of per car, replace wooden tanks. *1888: Tank-car manufacturers sell units directly to the oi ...

Flatcar
A flatcar (US) (also flat car, or flatbed) is a piece of rolling stock that consists of an open, flat deck mounted on trucks (US) or bogies (UK) at each end. Occasionally, flat cars designed to carry extra heavy or extra large loads are mounted on a pair (or rarely, more) of bogies under each end. The deck of the car can be wood or steel, and the sides of the deck can include pockets for Side stake, stakes or tie-down points to secure loads. Flatcars designed for carrying machinery have sliding chain assemblies recessed in the deck. Flatcars are used for loads that are too large or cumbersome to load in enclosed cars such as boxcars, but which will not be harmed by the weather. They are also often used to transport intermodal containers (shipping containers) or Semi-trailer, trailers as part of intermodal freight transport shipping. Specialized types Aircraft parts flatcars Aircraft parts were hauled via conventional Boxcar, freight cars beginning in World War II. However, gi ...

Silver City, Pinos Altos And Mogollon Railroad
Silver City, Pinos Altos and Mogollon Railroad (SC, PA&M) was a narrow gauge railway serving copper mines along the Continental Divide in the mountains of southwestern New Mexico. The communities of Silver City and Pinos Altos developed as 19th century miners recovered easily extracted gold and silver from ore deposits of the area. Standard-gauge Santa Fe Railroad reached Silver City in 1886, and SC, PA&M was incorporated 24 August 1889 to build a railway north to Mogollon, New Mexico. Construction was limited to of grading until Wisconsin-based Comanche Mining and Smelting purchased the railroad and the Pinos Altos mining claims of George Hearst in 1903 after horse-drawn ore transport became uneconomical. The Silver City smelter burned shortly after purchase, but was rebuilt with three blast furnaces and a reverberatory furnace to handle 225 tons of ore per day. Two Shay locomotives were moved to Silver City in August 1905 from the Gilpin tramway of Gilpin County, Colorado ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lima Locomotive Works
Lima Locomotive Works (LLW) was an American firm that manufactured railroad locomotives from the 1870s through the 1950s. The company's name is derived from the location of its main manufacturing plant in Lima, Ohio ( ). The shops were located between the Erie Railroad main line, the Baltimore and Ohio Railroad, Baltimore & Ohio's Cincinnati-Toledo main line and the New York, Chicago and St. Louis Railroad, Nickel Plate Road main line and shops. The company produced the Shay locomotive, Shay geared steam locomotive, geared logging steam locomotive, developed by Ephraim Shay, and for William E. Woodard's Superpower steam, "Super Power" advanced steam locomotive concept – exemplified by the prototype Berkshire locomotive, 2-8-4 Berkshire, Lima demonstrator A-1. In World War II the Lima plant produced the M4A1 version of the M4 Sherman tank. History In 1878, James Alley contracted the Lima Machine Works to build a steam locomotive that Ephraim Shay had designed. In Apr ...

Colorado And Southern Railway
The Colorado and Southern Railway was an American Railroad classes#Class I, Class I railroad in the western United States that operated independently from 1898 to 1908, then as part of the Chicago, Burlington and Quincy Railroad until it was absorbed into the Burlington Northern Railroad in 1981. The railway began as the consolidation of bankrupt railroads in 1898. The Colorado Central Railroad and Cheyenne and Northern Railway were brought together to form the Union Pacific, Denver and Gulf Railway in 1890. When Union Pacific went bankrupt in 1893 they were separated from the Union Pacific and united with the Denver, Leadville and Gunnison Railway and others, by Frank Trumbull to form the Colorado and Southern Railroad in 1898.

Passenger Car (rail)
A passenger railroad car or passenger car (American English), also called a passenger carriage, passenger coach (British English and International Union of Railways), or passenger bogie (Indian English) is a railroad car that is designed to carry passengers, usually giving them space to sit on train seats. 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, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
