Level Crossings
A level crossing is an intersection where a railway line crosses a road, path, or (in rare situations) airport runway, at the same level, as opposed to the railway line or the road etc. crossing over or under using an overpass or tunnel. The term also applies when a light rail line with separate right-of-way or reserved track crosses a road in the same fashion. Other names include railway level crossing, railway crossing (chiefly international), grade crossing or railroad crossing (chiefly American), road through railroad, criss-cross, train crossing, and RXR (abbreviated). There are more than 100,000 level crossings in Europe and more than 200,000 in North America. Road-grade crossings are considered incompatible with high-speed rail and are virtually non-existent in European high-speed train operations.

Horse-drawn Vehicle
A horse-drawn vehicle is a piece of equipment pulled by one or more horses. These vehicles typically have two or four wheels and were used to carry passengers or a load. They were once common worldwide, but they have mostly been replaced by automobiles and other forms of self-propelled transport but are still in use today. General Horses were domesticated circa 2000 BCE. Before that oxen were used. Historically, a wide variety of arrangements of horses and vehicles have been used, from chariot racing, which involved a small vehicle and four horses abreast, to horsecars or trollies, which used two horses to pull a car that was used in cities before electric trams were developed. A two-wheeled horse-drawn vehicle is a cart (see various types below, both for carrying people and for goods). Four-wheeled vehicles have many names – one for heavy loads is most commonly called a wagon. Very light carts and wagons can also be pulled by Donkey, donkeys (much smaller than horses), pony ...

Grade Crossing Signals
Level crossing signals are electronic warning devices for road vehicles at railroad level crossings. Level crossings can be operated in various ways. In some countries such as the UK, the warning devices are more often than not activated by remote control, I.e. an operator pressing buttons. However, the majority of countries have automated systems. Automated level crossings are found in most developed nations and vary greatly, but this page in particular is specific to the United States. Such equipment works as follows: The basic signal consists of flashing red lights, a crossbuck and an alarm (either a bell, a speaker that mimics a bell sound or an electronic siren), attached to a mast. At most crossings, the signals will activate about 30 seconds before the train arrives but there are sensors measuring speed so that the crossing knows when to activate; so, the slower the train is, the longer the delay and the faster the train is, the earlier the crossing activates. In some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hixon Rail Crash
On 6 January 1968, a low-loader transporter carrying a 120-ton electrical transformer was struck by a British Rail express train on a recently installed automatic level crossing at Hixon, Staffordshire, England. The collision resulted in 11 deaths and 45 people injured, and led to improvements in signage around automatic level crossings. Background In the 1950s, British Railways found that the cost of manning 2,400 level crossings had risen past £1 million per annum, with some locations seeing a tenfold increase. In the Post-war Britain (1945–1979), post-war labour market it was often difficult to recruit crossing keepers, the job itself being a responsible but rather dull occupation. In addition, manually operated crossings often caused long delays to road traffic because of the need to close the gates and clear the distant Railway signal, signal before the approaching train reached it. In October 1956, senior members of Her Majesty's Railway Inspectorate (HMRI) embarked o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dalfsen Train Crash
The Dalfsen train crash occurred on 23 February 2016 when a passenger train collided with a tracked elevated work platform on a level crossing at Dalfsen, Overijssel, Netherlands. One person was killed and six were injured, one seriously. Accident At 08:50 UTC+1, CET (07:50 coordinated Universal Time, UTC), a passenger train collided with an elevated work platform at Dalfsen, Overijssel, Netherlands. The crane, from company ''Van den Brink'' in Barneveld (town), Barneveld, was being driven slowly across the single-track line when it was hit by the train. Its driver had waited at the crossing while a westbound train passed, but then started to cross and was hit by an eastbound train. The train involved was a Spurt (Dutch Railways), Spurt GTW 2/8 train, travelling from to . All four vehicles were derailed. At the time of the crash, the train had fifteen passengers on board. One person, the driver of the train, was killed. Six were injured, with one person sustaining serious injur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braking Distance
A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction. Background Most brakes commonly use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat, though other methods of energy conversion may be employed. For example, regenerative braking converts much of the energy to electrical energy, which may be stored for later use. Other methods convert kinetic energy into potential energy in such stored forms as pressurized air or pressurized oil. Eddy current brakes use magnetic fields to convert kinetic energy into electric current in the brake disc, fin, or rail, which is converted into heat. Still other braking methods even transform kinetic energy into different forms, for example by transferring the energy to a rotating flywheel. Brakes are generally a ...

Mass
Mass is an Intrinsic and extrinsic properties, intrinsic property of a physical body, body. It was traditionally believed to be related to the physical quantity, quantity of matter in a body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particle, elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple Mass in special relativity, definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure (mathematics), measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the Force, strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is Mass versus weight, not the same as weight, even though mass is often determined by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
