An adhesion railway relies on adhesion traction to move the train.
Boston is the capital city and most populous municipality of the Commonwealth of Massachusetts in the United States.
A brake is a mechanical device that inhibits motion by absorbing energy from a moving system.
A brake run on a roller coaster is any section of track meant to slow or stop a roller coaster train.
A brake shoe is the part of a braking system which carries the brake lining in the drum brakes used on automobiles, or the brake block in train brakes and bicycle brakes.
A dead man's switch (for other names, see alternative names) is a switch that is automatically operated if the human operator becomes incapacitated, such as through death, loss of consciousness, or being bodily removed from control.
An eddy current brake, also known as an induction brake, electric brake or electric retarder, is a device used to slow or stop a moving object by dissipating its kinetic energy as heat.
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.
Electromagnetic brakes (also called electro-mechanical brakes or EM brakes) slow or stop motion using electromagnetic force to apply mechanical resistance (friction).
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another.
The Green Line is a light rail system run by the Massachusetts Bay Transportation Authority (MBTA) in the Boston, Massachusetts, metropolitan area.
High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks.
Light rail, light rail transit (LRT), or fast tram is a form of urban rail transport using rolling stock similar to a tramway, but operating at a higher capacity, and often on an exclusive right-of-way.
A magnet is a material or object that produces a magnetic field.
A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material (an element, compound, or alloy) that is typically hard when in solid state, opaque, shiny, and has good electrical and thermal conductivity.
Principle of the burn cutting Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the U.S.) and oxy-fuel cutting are processes that use fuel gases and oxygen to weld and cut metals, respectively.
In road vehicles, the parking brake, also called hand brake, emergency brake, or e-brake, is used to keep the vehicle stationary and in many cases also perform an emergency stop.
The PCC (Presidents’ Conference Committee) is a streetcar (tram) design that was first built in the United States in the 1930s.
A pine is any conifer in the genus Pinus,, of the family Pinaceae.
Rail transport is a means of transferring of passengers and goods on wheeled vehicles running on rails, also known as tracks.
Rail transport in Sweden uses a network of 13,000 km of track, the 21st largest in the world.
A railroad switch, turnout, or points 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 San Francisco cable car system is the world's last manually operated cable car system.
The Southeastern Pennsylvania Transportation Authority (SEPTA) is a regional public transportation authority that operates bus, subway / elevated rail line, commuter and light rail line, and electric trolleybus services to nearly 4 million people in five counties in and around Philadelphia, Pennsylvania.
A spring is an elastic object that stores mechanical energy.
A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine.
The track on a railway or railroad, also known as the permanent way, is the structure consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade.
A tram (also tramcar; and in North America streetcar, trolley or trolley car) is a rail vehicle which runs on tramway tracks along public urban streets, and also sometimes on a segregated right of way.
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants.
X 2000, also called X2, is a tilting train operated by SJ in Sweden.
