Flange-bearing Frog
A flange-bearing frog, often abbreviated FBF, is a type of frog in which the flange of the wheel on a railway vehicle supports the weight of the vehicle. In conventional practice, the tread of the wheel rests on the head of the rail and bears the weight of the vehicle, while the flange is used to keep the vehicle in the gauge of the track. Modern flange-bearing frogs for use in freight railroad applications are a relatively recent development as a means to reduce maintenance costs associated with turnouts and diamonds, where rails must cross one another. History Flange-bearing frogs have been used by street railways for more than 200 years as a means of reducing noise pollution in populated urban settings.Barkan, Dr. Christopher.

In 1995, Robert Willow filed a patent in the United States adapting this concept for use in mainline freight and passenger service. ...

OWLS Diamond Champaign
Owls are birds from the order Strigiformes (), which includes over 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl. Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except the polar ice caps and some remote islands. Owls are divided into two families: the true (or typical) owl family, Strigidae, and the barn-owl family, Tytonidae. A group of owls is called a "parliament". Anatomy Owls possess large, forward-facing eyes and ear-holes, a hawk-like beak, a flat face, and usually a conspicuous circle of feathers, a facial disc, around each eye. The feathers making up this disc can be adjusted to sharply focus sounds from varying distances ont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad Switch
A railroad switch (), turnout, or ''set ofpoints () is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off. The most common type of switch consists of a pair of linked tapering rails, known as ''points'' (''switch rails'' or ''point blades''), lying between the diverging outer rails (the ''stock rails''). These points can be moved laterally into one of two positions to direct a train coming from the point blades toward the straight path or the diverging path. A train moving from the narrow end toward the point blades (i.e. it will be directed to one of the two paths, depending on the position of the points) is said to be executing a ''facing-point movement''. For many types of switch, a train coming from either of the converging directions will pass through the switch regardless of the position of the points, as the vehicle's wheels will force the points to mov ...

Transportation Technology Center
The Transportation Technology Center (TTC) is a railroad equipment testing and training facility located northeast of Pueblo, Colorado, owned by the Federal Railroad Administration (FRA). It was built in 1971 as the High Speed Ground Test Center (HSGTC) for the Department of Transportation (DOT) and its original purpose was to test several hovertrain concepts. When those projects were completed in the 1970s, the site was handed to the FRA. Since October 2022, operations at the TTC have been managed by ENSCO, Inc. (ENSCO) under a "Indefinite Duration, Indefinite Quantity" (IDIQ) contract establishing responsibility for research and development, testing, engineering, and training services at the TTC. History Site selection Two United States Department of Commerce initiatives are credited with the genesis of the HSGTC: the Northeast Corridor Transportation Project (1964) and the High Speed Ground Transportation Act of 1965, which created the Office of High Speed Ground Transport ...

Waiver
A waiver is the voluntary relinquishment or surrender of some known right or privilege. Regulatory agencies of state departments or the federal government may issue waivers to exempt companies from certain regulations. For example, a United States law restricted the size of banks, but when banks exceeded these sizes, they obtained waivers. In another example, the United States federal government may issue waivers to individual states so that they may provide Medicaid in different ways than the law typically requires. While a waiver is often in writing, sometimes a person's words can also be used as a counteract to a waiver. An example of a written waiver is a disclaimer, which becomes a waiver when accepted. When the right to hold a person liable through a lawsuit is waived, the waiver may be called an exculpatory clause, liability waiver, legal release, or hold harmless clause. In some cases, parties may sign a "non-waiver" contract which specifies that no rights are wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diamond Crossing
A double junction is a Junction (rail), railway junction where a double-track railway splits into two double track lines. Usually, one line is the Main line (railway), main line and carries traffic through the junction at normal speed, while the other track is a branch line that carries traffic through the junction at reduced speed. A number of configurations are possible. At grade Diamond The simplest and oldest arrangement consists of two Railroad switch, turnouts (points) and a fixed Diamond crossing. Because the diamond needs to be relatively coarse, say 1 in 8, the curve radius is necessarily small, leading to a speed of perhaps . This type of junction is common on street-running tramways, where speeds are quite low and junction must fit into the available road space. Because the points are close together, the entire junction can be controlled by the mechanical point rodding of a single signal box. Signal passed at danger (SPAD) protection — A train from R to P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad Yard
A rail yard, railway yard, railroad yard (US) or simply yard, is a series of tracks in a rail network for storing, sorting, or loading and unloading rail vehicles and locomotives. Yards have many tracks in parallel for keeping rolling stock or unused locomotives stored off the main line, so that they do not obstruct the flow of traffic. Cars or wagons are moved around by specially designed yard switchers (US) or shunters, a type of locomotive. Cars or wagons in a yard may be sorted by numerous categories, including railway company, loaded or unloaded, destination, car type, or whether they need repairs. Yards are normally built where there is a need to store rail vehicles while they are not being loaded or unloaded, or are waiting to be assembled into trains. Large yards may have a tower to control operations. Many yards are located at strategic points on a main line. Main-line yards are often composed of an up yard and a down yard, linked to the associated direction of travel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
