Rail or rails may refer to:
A railroad switch (AE), turnout, or [set of] points (CE) 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.
A Jersey barrier, Jersey wall, or Jersey bump is a modular concrete or plastic barrier employed to separate lanes of traffic. It is designed to minimize vehicle damage in cases of incidental contact while still preventing vehicle crossovers resulting in a likely head-on collision. Jersey barriers are also used to reroute traffic and protect pedestrians and workers during highway construction. They are named after the U.S. state of New Jersey which first started using the barriers as separators between lanes of a highway in the 1950s.
In architecture, a deck is a flat surface capable of supporting weight, similar to a floor, but typically constructed outdoors, often elevated from the ground, and usually connected to a building. The term is a generalization from the deck of a ship. A level architectural deck may be intended for use by people, e.g., what in the UK is usually called a decked patio. "Roof deck" refers to the flat layer of construction materials to which the weather impervious layers are attached to a form a roof. It is known as the "roof deck", and they may be either level or sloped.
A safety barrier is a component which prevents passage into a dangerous area, and is commonly used to mitigate risk.
Guard rails, guardrails, railings or protective guarding, in general, are a boundary feature and may be a means to prevent or deter access to dangerous or off-limits areas while allowing light and visibility in a greater way than a fence. Common shapes are flat, rounded edge, and tubular in horizontal railings, whereas tetraform spear-headed or ball-finialled are most common in vertical railings around homes. Park and garden railings commonly in metalworking feature swirls, leaves, plate metal areas and/or motifs particularly on and beside gates.
The Willowbrook Rail Maintenance Facility is a GO Transit rolling stock maintenance facility located in the Willowbrook Yard in Toronto, Canada. The facility is west of Mimico station and is across the main tracks from the VIA Rail Toronto Maintenance Facility.
Tramway track is used on tramways or light rail operations. As with standard rail tracks, tram tracks have two parallel steel rails, the distance between the heads of the rails being the track gauge. When there is no need for pedestrians or road vehicles to traverse the track, conventional flat-bottom rail is used. However, when such traffic exists, such as in urban streets, grooved rails are used.
A stair lift is a mechanical device for lifting people, typically those with disabilities, up and down stairs. For sufficiently wide stairs, a rail is mounted to the treads of the stairs. A chair or lifting platform is attached to the rail. A person gets onto the chair or platform and is lifted up or down the stairs by the chair which moves along the rail.
Traffic barriers keep vehicles within their roadway and prevent them from colliding with dangerous obstacles such as boulders, sign supports, trees, bridge abutments, buildings, walls, and large storm drains, or from traversing steep (non-recoverable) slopes or entering deep water. They are also installed within medians of divided highways to prevent errant vehicles from entering the opposing carriageway of traffic and help to reduce head-on collisions. Some of these barriers, designed to be struck from either side, are called median barriers. Traffic barriers can also be used to protect vulnerable areas like school yards, pedestrian zones, and fuel tanks from errant vehicles. In pedestrian zones, like school yards, they also prevent children or other pedestrians from running onto the road.
A roofer, roof mechanic, or roofing contractor is a tradesman who specializes in roof construction. Roofers replace, repair, and install the roofs of buildings, using a variety of materials, including shingles, single-ply, bitumen, and metal. Roofing work includes the hoisting, storage, application, and removal of roofing materials and equipment, including related insulation, sheet metal, vapor barrier work, and green technologies rooftop jobs such as vegetative roofs, rainwater harvesting systems, and photovoltaic products, such as solar shingles and solar tiles.
Sandite is a substance used on railways in the UK, Ireland, US, the Netherlands and Belgium to combat leaves on the line, which can cause train wheels to slip and become damaged with flat spots. Sandite consists of a mixture of sand, antifreeze and steel shot.
The rail profile is the cross sectional shape of a railway rail, perpendicular to its length.
Roof edge protection is fall protection equipment most commonly used during the construction of commercial buildings or residential housing. They can be used along with timber, steel, or concrete structures. It often consists of a toe board, a main guard rail and an intermediate rail.". Roof edge protection can take the form of personal fall arrest systems (PFAS), fall restraint systems, guardrail systems, warning line systems, safety monitors, or ladders. Since construction is one of the most dangerous professions in the world, roof edge protection offers much-needed protection against falls from heights which is one of the primary causes of fatalities for workers.
Cable railings, or wire rope railings, are safety rails that use horizontal or vertical cables in place of spindles, glass and mesh for infill.
Trinity Industries Inc. is an American industrial corporation that owns a variety of businesses which provide products and services to the industrial, energy, transportation and construction sectors.
A current collector is a device used in trolleybuses, trams, electric locomotives and EMUs to carry electric power (current) from overhead lines, electric third rails, or ground-level power supplies to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for rails are mounted on the bogies.
A roadway departure is a type of incident that occurs when a vehicle leaves the roadway. Such incidents can lead to a single-vehicle collision.
A guide rail is a device or mechanism to direct products, vehicles or other objects through a channel, conveyor, roadway or rail system.
A snow guard is a device used to retain snow and ice from falling from one surface to a lower one; in contemporary usage, they are installed to prevent snow/ice pack from avalanching and damaging people, plants, and property below. They are most commonly installed in multiples or rows on a structure's roof surface, as a form of avalanche control. Snow guards are installed with a specific quantity and pattern based on the shape, size and pitch of the roof to provide the most uniform system of retention possible. Snow guards are not fully intended to completely hold back the snow as this would cause major leak issues when the snow melts. They are however built to separate the snow to allow it to break apart into smaller pieces/sections so that, if they do fall in rising temperatures and thawing conditions, the likelihood of having someone injured by the falling pile of snow is minimized.
