2015 Philadelphia Train Derailment
On May 12, 2015, an Amtrak ''Northeast Regional'' train from Washington, D.C. bound for New York City derailed and wrecked on the Northeast Corridor near the Kensington neighborhood of Philadelphia, Pennsylvania. Of 238 passengers and 5 crew on board, 8 were killed and over 200 injured, 11 critically. The train was traveling at in a zone of curved tracks when it derailed. Some of the passengers had to be extricated from the wrecked cars. Many of the passengers and local residents helped first responders during the rescue operation. Five local hospitals treated the injured. The derailment disrupted train service for several days. The National Transportation Safety Board determined that the derailment was caused by the train's engineer (driver) becoming distracted by other radio transmissions and losing Situation awareness, situational awareness, and said that it would have been prevented by positive train control, a computerized speed-limiting system that was operational elsewh ...

Eastern Daylight Time
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama, Colombia, mainland Ecuador, Peru, and a small portion of westernmost Brazil in South America, along with certain Caribbean and Atlantic islands. Places that use: * Eastern Standard Time (EST), when observing standard time (autumn/winter), are five hours behind Coordinated Universal Time ( UTC−05:00). * Eastern Daylight Time (EDT), when observing daylight saving time (spring/summer), are four hours behind Coordinated Universal Time ( UTC−04:00). On the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT leaving a one-hour "gap". On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, thus "duplicating" one hour. Southern parts of the zone (Panama and the Caribbean) do not observe daylight saving time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Situation Awareness
Situational awareness or situation awareness (SA) is the perception of environmental elements and events with respect to time or space, the comprehension of their meaning, and the projection of their future status. An alternative definition is that situation awareness is adaptive, externally-directed consciousness that has as its products knowledge about a dynamic task environment and directed action within that environment. However, while Endsley's definition is widespread, the theory and measures used to develop it do not attract widespread consensus. SA is a nebulous concept which shares many criticisms with those levelled at the idea of consciousness itself. An early criticism of the definition and model illustrates a reasoning fallacy which has yet to be addressed in the development of SA definition and theory: Situation awareness has been recognized as a critical, yet often elusive, foundation for successful decision-making across a broad range of situations, many of which ...

Frankford Junction
Frankford Junction is a railroad junction, and former junction station, located on the border between the Harrowgate neighborhood of Philadelphia and Frankford, Philadelphia. At the junction, the 4-track Northeast Corridor line from Trenton connects with the 2-track Atlantic City Line from Atlantic City in the northeastern portion of Philadelphia about northeast of North Philadelphia station. It lies near the intersection of Frankford Avenue and Butler Street, to the west of the interchange between Interstate 95 and the approach to the Betsy Ross Bridge. It has been used for rail transportation since 1832 but has not served as a station since October 4, 1992. Overview The junction has seen a mass of freight and passenger service throughout its existence. In 1832 the Philadelphia and Trenton Railroad (P&T) was formed and started service with a small yard. The line extended southwest of the junction and on to destinations north. In 1871 the railroad was leased by the Penn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Degree Of Curvature
Degree of curve or degree of curvature is a measure of curvature of a circular arc used in civil engineering for its easy use in layout surveying. Definition The degree of curvature is defined as the central angle to the ends of an agreed length of either an arc or a chord; various lengths are commonly used in different areas of practice. This angle is also the change in forward direction as that portion of the curve is traveled. In an ''n''-degree curve, the forward bearing changes by ''n'' degrees over the standard length of arc or chord. Usage Curvature is usually measured in radius of curvature. A small circle can be easily laid out by just using radius of curvature, but degree of curvature is more convenient for calculating and laying out the curve if the radius is large as a kilometer or a mile, as it needed for large scale works like roads and railroads. By using degrees of curvature, curve setting can be easily done with the help of a transit or theodolite and a chai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad Engineer
A train driver, engine driver, engineman or locomotive driver, commonly known as an engineer or railroad engineer in the United States and Canada, and also as a locomotive handler, locomotive operator, train operator, or motorman, is a person who drives a train, multiple unit or a locomotive. The driver is in charge of, and is responsible for the mechanical operation of the train, train speed, and all of the train handling (also known as brake handling). In American English, a hostler (also known as a switcher) moves engines around rail yards, but does not take them out on the normal tracks; the British English equivalent is a shunter. Train drivers must follow certain guidelines for driving a train safely. For instance, in general, train drivers are encouraged to favour longer stopping distances as this promotes vehicle health, safety, and passenger comfort. Career progression For many American railroads, the following career progression is typical: assistant conductor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siemens ACS-64
The Siemens ACS-64, or Amtrak Cities Sprinter, is an electric locomotive designed by Siemens Mobility for use on the Northeast Corridor (NEC) and the Keystone Corridor in the northeastern United States. The design was based on locomotives Siemens created for use in Europe and Asia, but with changes to comply with American standards. The ACS-64 is built at the Siemens factory in Florin, California, located outside of Sacramento. The first 70 locomotives were built for Amtrak to replace the railroad's fleet of aging AEM-7 and unreliable HHP-8 locomotives. The first ACS-64 entered service in February 2014 and deliveries continued until August 2016. SEPTA Regional Rail in Southeastern Pennsylvania operates a fleet of 15 ACS-64s since August 2018, on the agency's commuter rail routes. Design The design is based on the EuroSprinter and the Vectron platforms, which Siemens sells in Europe and Asia. Significant structural changes to the design were made to comply with American cras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
30th Street Station
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Reckless Endangerment
Endangerment is a type of crime involving conduct that is wrongful and reckless or wanton, and likely to produce death or grievous bodily harm to another person. There are several kinds of endangerment, each of which is a criminal act that can be prosecuted in a court. In some U.S. states, such as Florida, substantially similar language is used for the crime of culpable negligence. The offense is intended to prohibit and therefore deter reckless or wanton (of a cruel or violent action, deliberate and unprovoked conduct) that wrongfully creates a substantial risk of death or serious injury to others. Various laws specify several types of endangerment: *Child endangerment and animal endangerment: placing a child or animal in a potentially harmful situation, either through negligence or misconduct. *Reckless endangerment: A person commits the crime of reckless endangerment or wanton endangerment if the person recklessly engages in conduct which creates substantial jeopardy of sev ...

Involuntary Manslaughter
Manslaughter is a common law legal term for homicide considered by law as less culpable than murder. The distinction between murder and manslaughter is sometimes said to have first been made by the ancient Athenian lawmaker Draco in the 7th century BC. The definition of manslaughter differs among legal jurisdictions. Types Voluntary In voluntary manslaughter, the offender had intent to kill or seriously harm, but acted "in the moment" under circumstances that could cause a reasonable person to become emotionally or mentally disturbed. There are mitigating circumstances that reduce culpability, such as when the defendant kills only with an intent to cause serious bodily harm. Voluntary manslaughter in some jurisdictions is a lesser included offense of murder. The traditional mitigating factor was provocation; however, others have been added in various jurisdictions. The most common type of voluntary manslaughter occurs when a defendant is provoked to commit homicide. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
