Sperry Rail Service
Sperry Rail Service is a rail inspection company founded in 1928 by Elmer Ambrose Sperry. The company was the first in the world to offer nondestructive testing of railroad track. Since its formation, Sperry has been contracted by most of the major railroads in North America to inspect rail. To accomplish this task, the company operates a fleet of rail service vehicles that travel along railroads to detect defects. While most prominent in North America, Sperry operates on every continent. History Defect detection need There were many early useless efforts of rail defect detecting device development in the late 19th century. Serious train derailments, which were blamed on transverse fissures, were increasing. One of them occurred in 1911, in Manchester, New York, killing 29 and seriously injuring 60. Another killed 21 and injured over 100 near Victoria, Mississippi, in October 1925. The need for dependable rail inspection became apparent. First developments Dr. Sperry ...

Elmer Sperry
Elmer Ambrose Sperry Sr. (October 12, 1860 – June 16, 1930) was an American inventor and entrepreneur, most famous for construction, two years after Hermann Anschütz-Kaempfe, of the gyrocompass and as founder of the Sperry Gyroscope Company. He was known as the "father of modern navigation technology". Sperry's compasses and stabilizers were adopted by the United States Navy and used in both world wars. He also worked closely with Japanese companies and the Japanese government and was honored after his death with a volume of reminiscences published in Japan. Early life Sperry was born in Cincinnatus, New York, on October 12, 1860, to Stephen Decatur Sperry and Mary Burst. His mother died the next day, from complications from his birth. He was of English ancestry. His family had been in what is now the Northeastern United States since the 1600s, and his earliest American ancestor was an English colonist named Richard Sperry. Sperry spent three years at the State Normal Sch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad Speeder
A speeder (also known as a section car, railway motor car, putt-putt, track-maintenance car, crew car, jigger, trike, quad, trolley, inspection car, or a draisine) is a small railcar formerly used around the world by track inspectors and work crews to move quickly to and from work sites. Although slow compared to a train or car, it is called ''speeder'' because it is faster than a human-powered vehicle such as a handcar. Motorised inspection cars date back to at least 1896, when it was reported that the U.S. Daimler Motor Company created a gasoline-powered rail inspection car capable of 15 mph (24 km/h). In the 1990s, many speeders were replaced by pickup trucks or sport utility vehicles with additional flanged wheels that could be lowered for travelling on rails, called "road–rail vehicles" or hi-rails for "highway-railroad". Speeders are collected by hobbyists, who refurbish them for excursions organized by the North American Railcar Operators Association in the U.S ...

Railway Service Companies Of The United States
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in Track (rail transport), tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on Railroad tie, sleepers (ties) set in track ballast, ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Doodlebug (rail Car)
Doodlebug or hoodlebug is a nickname in the United States for a type of self-propelled railcar most commonly configured to carry both passengers and freight, often dedicated baggage, mail or express, as in a combine. The name is said to have derived from the insect-like appearance of the units, as well as the slow speeds at which they would doddle or "doodle" down the tracks. Early models were usually powered by a gasoline engine, with either a mechanical drive train or a generator providing electricity to traction motors ("gas-electrics"). In later years, it was common for doodlebugs to be repowered with a diesel engine. Doodlebugs sometimes pulled an unpowered trailer car, but were more often used singly. They were popular with some railroads during the first part of the 20th century to provide passenger and mail service on lightly used branch lines at less expense than with a train consisting of a locomotive and coaches with larger crew. Several railroads, mostly small reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New York Central
The New York Central Railroad was a railroad primarily operating in the Great Lakes and Mid-Atlantic regions of the United States. The railroad primarily connected greater New York and Boston in the east with Chicago and St. Louis in the Midwest, along with the intermediate cities of Albany, Buffalo, Cleveland, Cincinnati, Detroit, Rochester and Syracuse. New York Central was headquartered in New York City's New York Central Building, adjacent to its largest station, Grand Central Terminal.

Ultrasonic Inspection
Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion. Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites, albeit with less resolution. It is used in many industries including steel and aluminium construction, metallurgy, manufacturing, aerospace, automotive and other transportation sectors. History The first efforts to use ultrasonic testing to detect flaws in solid material occurred in the 1930s.''Nondestructive ...
