A guide rail is a system designed to guide vehicles back to the roadway and away from potentially hazardous situations. There is no legal distinction between a guide rail and a guard rail. Several types of roadway guide rail exist; all are engineered to guide vehicular traffic on roads or bridges. Such systems include W-beam, box beam, cable, and concrete barrier.

These are referred to as flexible barriers because they will deflect when struck by a typical passenger car or light truck. Impact energy is dissipated through tension in the rail elements, deformation of the rail elements, posts, soil and vehicle bodywork, and friction between the rail and vehicle. Components of a standard guiderail (A-profile): S – guardrail, D – distance piece/spacer, P – sigma post ' include box beam guide rail, heavy post blocked out corrugated guide rail and thrie-beam guide rail. Thrie-beam is similar to corrugated rail, but it has three ridges instead of two.

Translohr guide rail Translohr in Medellín The Translohr system is intended to provide a tram or light rail-like experience compared to regular buses or trolleybuses. Unlike other guided bus systems (including the similar but incompatible Guided Light Transit system developed by Bombardier Transportation), Translohr cars are permanently fixed to guide rails, and cannot divert from them, similar to traditional steel-wheeled rail vehicles. Since the guide rail automatically guides the vehicle along its route, there are minimal steering controls in the driver's cab. Accelerating and braking are the only functions the driver controls.

Their net weight is , depending upon the number of car sections. Translohr LRVs cannot run without a guide rail therefore they are not classified as buses. Hence, vehicles that are used on the Clermont-Ferrand network do not have license plates.

The crank was only seven inches in length, and the engine was designed to readily make 600 revolutions a minute, and maintain a speed of 100 miles an hour with a full train of passenger cars. In a true line with, and fifteen feet directly above, the face of the track rail was the lower face of a guide rail, supported from posts arranged along the side of the track, and on the sides of this guide rail run pairs of rubber- faced trolley wheels attached to the top of the locomotive and the cars. The guide rail was a simple stringer of yellow pine, 4¼ by 8 inches in section, and the standards on which the wheels are journaled were placed far enough apart to allow a space of 6 inches between the continuous faces of each pair of wheels, thus affording 1¾ inches for lateral play, or sidewise movement toward or from the guard rail, it being designed that the guide rail shall be arranged in the exact line of the true center of gravity of the cars and locomotive. The standards were bolted to six-inch wide strap iron attached to and extending across the top of the car.

The compartments were each four feet wide and five feet long, the seats facing each other. Only one rail of the old single track was used, as only one guide rail had been erected, except at the ends of the route, for switching purposes, but the width of the cars and motor was such that it only required the erection of another guide rail, for the utilizing of the other track rail, to form a regular double-track road of the Boynton pattern. The section of railroad on which this system has been operated was only two miles long, in which distance the curves were considerable, but, although they were mostly in one direction, the indications of wear upon the traction wheels, and upon the guide rail and trolley wheels, were hardly perceptible. During a portion of the season, when the summer travel to Coney Island was at its height, trains were run on regular schedule time, 50 three- car-trains daily each way, carrying from 1 to 300 passengers per trip.

The two types of vehicle have recently converged in the form of the rubber wheeled tram, which uses tram-like overhead power and a single road-embedded rail as a guideway, a few of which allow the vehicle to leave the guide rail and operate as a traditional electric bus.

A unique demonstration electrically powered suspension line was built by the Scottish engineer George Bennie near Glasgow. Two propellers delivered in a short burst for acceleration to the cruise speed of 160 km/h. It was not a true monorail as it used an overhead running rail and a guide rail below.

The bolt carrier has a built-in guide rail used for reloading from 10-round stripper clips (from the SKS rifle). Despite their similarity, vz. 58 magazines are not interchangeable with those of the Kalashnikov-pattern weapons. An interesting feature on this rifle is the ability to quickly change the type of stock.

The confined gas accelerates the movable projectile down the length of the tube imparting sufficient velocity to sustain the projectile's travel once the action of the gas ceases at the end of the tube or muzzle. Alternatively, acceleration via electromagnetic field generation may be employed in which case the tube may be dispensed with and a guide rail substituted.

The Chairman presented Messrs. Killick and Cochran's suggestion an estimate for placing a new wrought iron top guide rail for gates, the Secretary was instructed to request them to proceed with the work at once and to ascertain if they consider the ground runners in good order and also if the new chains supplied by them had been tested and to what extent.

Though basically the same look, they went through Mark I, II, III, and IV by 1958. When the Monorail, Submarine Voyage, and Matterhorn debuted in 1959, so did a new fleet with an all-new look – the "Mark Vs". The next design, Mark VI, came in 1964. It was at this time (1965) the center guide rail was first installed.

The Montreal Metro, Lille Metro, Toulouse Metro, and most parts of Santiago Metro, use concrete. The Busan Subway Line 4 employs a concrete slab. The Paris Métro, Mexico City Metro, and the non- underground section of Santiago Metro, use H-Shaped hot rolled steel, and the Sapporo Municipal Subway uses flat steel. The Sapporo system is unique because it uses a single central guide rail only.

The submersible mixer is operated by an electric motor, which is coupled to the mixer's propeller, either direct-coupled or via a planetary gear-reducer. The propeller rotates and creates liquid flow in the tank, which in turn keeps the solids in suspension. The submersible mixer is typically installed on a guide rail system, which enables the mixer to be retrieved for periodic inspection and preventive maintenance.

It was a one- person, small in a modern sense, car propelled by maglev. The car was designed to be levitated by magnets, and was intended to be developed for high-speed transportation systems. The Levicar was very light and when raised off its guide rail by the magnetic it only required a blower in the back to propel it. A working model was actually built.

Levicar concept Levicar was a concept car Ford displayed in 1959. It was a one-person, small in a modern sense, car propelled by maglev. The car was designed to be levitated by magnets, and was intended to be developed for high-speed transportation systems. The Levicar was very light and when raised off its guide rail by the magnetics it only required a blower in the back to propel it.

The Twin Turnpike featured a middle guide rail, which reduced damage to the cars. The main focus of the area where the Twin Turnpike was built was the Kissing Tower, a 330 foot tall tower. Himalaya was also added in 1975, which replaced the old Twin Ferris Wheels. But, Himalaya only operated there through the 1976 season, when it was moved near the Twin Turnpike, which it replaced the old Whipperoo.

The Hoggs Hollow Bridge has a 14-lane cross section: 6 collector lanes, 8 express lanes. The road surface and bridge decks require constant maintenance due to the wear and tear from high traffic volumes. Since 2001, an Ontario tall-wall concrete barrier has replaced the steel guide–rail in the median separating eastbound and westbound traffic. The late 1960s conventional truss lights have been replaced by high-mast lighting.

The switching arrangement was remarkably simple. In addition to an ordinary track switch, in which, however, the switch bar is made to throw only one rail, a connection was made by means of a vertical rod and upper switch bar with a shifting section of the guide rail, whereby, on the moving of the track rail and the setting of the signal, the guide rail was simultaneously moved, the adjustment being effected and both being locked in position according to the methods usual in ordinary railway practice. The passenger cars were each two stories in height, each story being divided lengthwise into nine separate compartments, each of which seated comfortably four passengers, thus providing seats for 72 passengers in each car. Each compartment had its own sliding door, and all the doors on the same floor of the car were connected by rods at the top and bottom with a lever in convenient reach of the brakeman, by whom the doors are all opened and closed simultaneously.

Avis Vintage Cars Avis Vintage Cars is a fixed track car ride with scaled-down Ford Model T cars fixed onto a concrete track with a single guide rail. The ride was relocated from its original location due to the placement of Mick Doohan's Motocoaster ride in 2007. The ride opened in 1981 with the park in the Rivertown area of the park. The fourteen replicas cars each seat four people and were purchased for A$12,000 each.

There are two systems which use this technology: the Guided Light Transit (GLT) and Translohr. The GLT "trams" are legally considered buses as they have steering wheels and can leave the fixed rail when requirements dictate e.g. when journeying to a depot while a Translohr "tram" cannot operate without a guidance rail and are generally not considered buses. With the development of technologies for self-guided vehicles, it is now possible to dispense with the guide rail.

The first begins with construction curves (splines) from which the 3D surface is then swept (section along guide rail) or meshed (lofted) through. A surface being created from curves. The second method is direct creation of the surface with manipulation of the surface poles/control points. Surface edit by poles From these initially created surfaces, other surfaces are constructed using either derived methods such as offset or angled extensions from surfaces; or via bridging and blending between groups of surfaces.

Before the park opened, the cars were tested without the bumpers, and were almost completely destroyed by the test drivers. Bumpers were fitted around the vehicle, but there were still problems with collisions, as a guide rail had yet to be implemented on the ride. Eventually the vehicles were fitted with spring-loaded bumpers to discourage collisions. The first fleet of Autopia cars were dubbed "Mark I". Throughout Disneyland's first few years, Autopia went through a few fleets, as the cars took much abuse.

The earliest versions of the M42 developed problems with the camshaft chain drive. The hydraulic tensioner, chain guides, idler wheel and rear lower chain case were updated to resolve wear problems experienced in the early versions of the M42. In September 1993, BMW redesigned the M42's timing chain guide rails, replacing the occasionally troublesome lower idler gear with a curved nylon guide rail. The idler gear's retaining bolt could break away from the timing case, often taking a chunk of alloy timing case with it.

On the GLT line in Nancy, more than one-third of the 10-km route has no guide rail, and steering is controlled entirely by the driver on those sections. The Nancy GLT system is operated by the Société de Transports de l'Agglomération Nancienne, or STAN. With two articulation points and a total length of , GLT vehicles are shorter than most modern trams, but long compared with conventional buses. They are designed to look like trams, but they are unidirectional and have bus-like rear-view mirrors.

Sketches published in 1915 of Kearney's underground monorail system Tube line across London Kearney patented an innovative underground monorail railway system, the Kearney High-Speed Tube, which used the effects of gravity to enhance acceleration and deceleration and reduce power consumption with a "roller coaster" type of motion; from shallow sub-surface stations, deep-level tube tunnels would fall away at a 1-in-7 gradient, enabling underground trains to reach an estimated before slowing down as they climbed to the next station. The trains were unusual in that they would run on a single rail with four double-flanged wheels under each carriage; wheels mounted on the roof would run along an upper guide rail above the train. This upper guide rail, along with the carriages' low centre of gravity and the gyroscopic effect of motion, would stabilise the train on the lower rail and reduce the side-to-side hunting oscillation, thus preventing derailments and allowing greater speeds. At least two models of the system were built, in 1905 and 1908, including dramatic extremes such as 1-in-3 gradients and S-bends.

The first launch was ordered for December 2, but again weather and technical problems delayed the operation. On December 4 the first rocket blasted off just after 10 AM. Set on a test ring without a guide rail, the rocket rose vertically for three seconds, but then the parachute deployed and dragged, burning, behind the vehicle. After less than seven seconds the engine cut out and soon the rocket fell back to the ground, landing 1,000 feet (300 meters) from the launch site. It exploded and burned upon impact, leaving little wreckage to examine.

Wheel alignment is important both to minimize wheel contact with the axle head and body as well as to limit the contact between the wheels and guide rail as the car travels down the track. There are 32 friction causing surfaces on a pinewood derby car. These include the surfaces of all four wheels which touch either the axle, the body or the track and the surfaces of all four axles which touch the wheel. Neglecting to polish and lubricate any of these 32 surfaces will result in degraded performance.

Elderly people, disabled people, and children are the most in danger of being crushed or losing a limb. In September 1975, the paternoster in Newcastle University's Claremont Tower was taken out of service after a passenger was killed when a car left its guide rail at the top of its journey and forced the two cars ascending behind it into the winding room above. In October 1988, a second non-fatal accident occurred in the same lift. A conventional lift was installed in its place in 1989–1990.

There are also some rubber-tired systems that use a central guide rail, such as the Sapporo Municipal Subway and the NeoVal system in Rennes, France. Advocates of this system note that it is much quieter than conventional steel- wheeled trains, and allows for greater inclines given the increased traction of the rubber tires. Some cities with steep hills incorporate mountain railway technologies in their metros. One of the lines of the Lyon Metro includes a section of rack (cog) railway, while the Carmelit, in Haifa, is an underground funicular.

One of the main aims of the system, to achieve a lower cost per kilometre than trams, has failed. Other French tramways achieve a cost per kilometre at least 10% lower than that for the guided bus. Similarly, the cost per person of the vehicles is also noticeably higher with the guided bus than a tram. Where snowfall is an issue, this system may not be practical: since the guide rail forms the return leg of the electrical circuit, accumulation of ice and snow on the rail could cause intermittent power interruptions to the vehicle.

Beginning in November 1997, in the course of renovation work in the leadup to the Schwebebahn's centenary in 2001, each weekend was spent completely replacing the railway's weightbearing structure. The steel claw fastener that was attached to the guide rail served to stabilize the overhead track during this work. On the night before the accident, work had ended during which parts of the overhead track, a few piers from the accident site, had been replaced. The night's work lagged so far behind schedule that the work site was left only ten minutes before the morning's first train from the Vohwinkel direction came along.

The lower level of the wheelhouse features a sleeping area and a sink to maintain the illusion of this being the captain's living quarters. The pilot signals the departure and arrival of Mark Twain using a horn and bell system, along with various signals to other river craft attractions. Because the riverboat travels along a hidden I-beam guide rail throughout the ride, the pilot does not maneuver the ship. Instead, the pilot serves as lookout for other river traffic, such as Davy Crockett's Explorer Canoes and the Rafts to Pirate's Lair on Tom Sawyer Island, and communicates his observations with the boiler engineer.

The first idea for rubber-tyred railway vehicles was the work of Scotsman Robert William Thomson, the original inventor of the pneumatic tyre. In his patent of 1846 he describes his 'Aerial Wheels' as being equally suitable for, "the ground or rail or track on which they run". The patent also included a drawing of such a railway, with the weight carried by pneumatic main wheels running on a flat board track and guidance provided by small horizontal steel wheels running on the sides of a central vertical guide rail. During the World War II German occupation of Paris, the Metro system was used to capacity, with relatively little maintenance performed.

Track saws (often referred to as plunge saws or plunge-cut saws) are a type of hand-held circular saw which slides on a guide rail during operation. This allows the operator to perform long and accurate cuts. Track saws, unlike hand-held circular saws, plunge into the material to a pre-determined depth during the cut, increasing operator safety and allowing for reduced splintering and tear-out; the depth-of-cut is not fixed and can be adjusted to be just slightly over the thickness of the board being cut. This property allows a track saw to also cut shallow grooves into the workpiece, if necessary.

CD and TCP systems cannot be used with canopies made of flexible materials, such as the Lexan polycarbonate canopy used on the F-16. Soviet VTOL naval fighter planes such as the Yakovlev Yak-38 were equipped with ejection seats which were automatically activated during at least some part of the flight envelope. Drag Extraction is the lightest and simplest egress system available, and has been used on many experimental aircraft. Halfway between simply "bailing out" and using explosive-eject systems, Drag Extraction uses the airflow past the aircraft (or spacecraft) to move the aviator out of the cockpit and away from the stricken craft on a guide rail.

Barriers are divided into three groups, based on the amount they deflect when struck by a vehicle and the mechanism the barrier uses to resist the impact forces. In the United States, traffic barriers are tested and classified according to the AASHTO Manual for Assessing Safety Hardware (MASH) standards, which recently superseded Federal Highway Administration NCHRP Report 350. Barrier deflections listed below are results from crash tests with a pickup truck traveling , colliding with the rail at a 25 degree angle.Roadside Design Guide, American Association of State Highway Transportation Officials, 2004, pages 5-10 to 5-23 ' include cable barriers and weak post corrugated guide rail systems.

Allen assigned set designer Alek Kowalcyk, who also provided the voice of the attraction's Ghost Host, to develop a dark ride vehicle that would be used in Forbidden haunted house. Kowalczyk created sketches of what he called the EPRV, or Electrically Propelled Rotating Vehicle, that would sit three passengers in each of its two rows. Each EPRV would have its own built- in motor, allowing the car to speed up, slow down, or stop completely as programmed. The cars would run on a main track in the center of the floor while a second guide rail would rotate the vehicle to face scenes as desired.

Data obtained from a crash simulation indicate the capability of the car body or guard rail structure to protect the vehicle occupants during a collision (and also pedestrians hit by a car) against injury. Important results are the deformations (for example, steering wheel intrusions) of the occupant space (driver, passengers) and the decelerations (for example, head acceleration) felt by them, which must fall below threshold values fixed in legal car safety regulations. To model real crash tests, today's crash simulations include virtual models of crash test dummies and of passive safety devices (seat belts, airbags, shock absorbing dash boards, etc.). Guide rail tests evaluate vehicle deceleration and rollover potential, as well as penetration of the barrier by vehicles.

Stock wheels (left) and modified (one gram) wheels (right) The force accelerating a pinewood derby car is gravity; the opposing forces are friction and air drag. Therefore, car modifications are aimed at maximizing the potential energy in the car design and minimizing the air drag and the friction that occurs when the wheel spins on the axle, contacts the axle head or car body, or contacts the track guide rail. Friction due to air drag is a minor, although not insignificant, factor. The wheel tread can be sanded or turned on a lathe and the inner surface of the hub can be tapered to minimize the contact area between the hub and body.

The Caen transport company, Twisto (CTAC), was the operator of the TVR system and called the system the "Tram". Service was provide by 24 three-section articulated vehicles, guided by a central non-supporting rail. The entire passenger line was guided, and in normal service the vehicles are powered by electricity drawn from an overhead wire through a pantograph. The vehicles had auxiliary diesel engines and steering wheels and were able to operate away from the guide rail, but only in diesel mode, and under normal operating conditions they ran only in electric mode when carrying passengers along the route, using their diesel engines only when travelling to and from the depot (garage).

Roadway view of bridge from its southeast end, 2012 A historic rehabilitation of the bridge completed in 2003 by the New Jersey Department of Transportation (NJDOT) with little visible change to the superstructure while components below the bridge deck and the cantilevered sidewalks were replaced. Round headed bolts replaced deteriorated rivets, a hollow steel rail barrier to protect the trusses was used in place of standard guide rail and historic style light fixtures were installed. Deteriorated elements were replaced and the original sidewalk railing was sandblasted, painted and re-installed. A historic bridge survey conducted by NJDOT from 1991–1994 determined that the bridge was eligible for listing on the New Jersey Register of Historic Places and the National Register of Historic Places.

Features may include controls for fully automatic operation; a high-level alarm indication, in the event of pump failure; and possibly a guide- rail/auto-coupling/pedestal system, to permit easy removal of pumps for maintenance. Traditional site constructed systems have the valve vault components installed in a separate structure. Having two structural components can lead to potentially serious site problems such as uneven settling between components which results in stress on, and failure of the pipes and connections between components. The development of a packaged pump station system combined all components into a single housing which not only eliminates uneven settling issues, but pre-plumbing and outfitting each unit prior to installation can reduce the cost and time involved with civil work and site labor.

A first railway project for the mountain, later known by the name , was presented in 1876 by Cordier; it was one of the far-flung ideas that the railway companies often had in the 19th century. Because classical rail has poor adherence, Cordier designed a raceway made of two granite rails embedded in concrete with a continuous guide rail between them. The line, with a terminus at the Quai de la Bourse, would be served by steam carriages with a capacity of only 30 places, but capable of running on public streets as well as its special track. Because of its technical complexity the line would have been hugely expensive, the 1:1 gradient to Bonsecours requiring no fewer than 30 viaducts spanning overall .

The weapon's spring extractor is installed inside the bolt head and enclosed in one of the locking lugs while the ejector is a fixed protrusion of the internal bolt carrier guide rail. The firearm uses a hammer-type firing mechanism and a trigger group that enables semi-automatic and fully automatic firing modes. The fire selector switch, which is also the manual safety toggle, can occupy one of three positions: the top "safe" setting (the trigger and bolt carrier are both disabled mechanically), the middle setting (marked with three dot symbols) produces continuous fire and the bottom setting (single dot) activates a disconnector for single fire mode. The weapon's barrel has a multipurpose muzzle attachment, which performs the role of a muzzle brake, flash suppressor and a mounting base for launching rifle grenades.

Nancy's fleet of 25 GLT vehicles use dual trolley poles to collect and return their electric power, in order to allow the use of existing wires constructed for use by the town's previous generation of trolleybuses and to permit operation, where desired by the transport authority, away from the guide rail. The Nancy vehicles follow a guidance rail on about 60% of the route, and thus the Nancy route uniquely is considered to be both a rubber- tyred tramway and a trolleybus line. The system was first brought into use for passenger service in February 2001, but operation was suspended from March 2001 through March 2002 while Bombardier performed upgrades to the vehicles. In Caen, the GLT fleet began operation in November 2002, incorporating the changes made to Nancy's vehicles during the upgrade.

These arms were hydraulically extended at the appropriate time and engaged a rail mounted above the power and signal rails, serving to steer the vehicle from the enclosed, single-lane guideway into the bypass areas where the guideway split to become two separate passing lanes. Since the system was centrally controlled and used hydraulics, there was a minimum actuation time that required headways to be around 30 seconds at the normal operating speed of 30 mph. It may be noted that, although the designed and advertised maximum operating speed was 30 mph, the actual cruise speed of the Fairlane system was lowered to about 25 mph, where it remained throughout the duration of its operating lifetime of approximately 12 years. Power was supplied at 480 V 60 Hz AC, in a corner-grounded Delta configuration, with the guide rail serving as the ground leg and the other two phases supplied on separate rails above the ground/guidance rail.

The guideway consisted of parallel steel I-beams providing the running surface, with a third steel channel running down the middle of the two providing the guide rail, emergency stopping surface, vehicle power and communications. Due to the rubber-on-steel running surfaces, the maximum climbing grade was about 10 degrees, and would be reduced in wet or snowy weather. In good weather the vehicles normally ran at 40 km/h in the low-speed sections, but could run as high as 80 km/h in high-speed sections. Vehicle control used a moving block control system, similar to those used on automated railways. Each vehicle had a small computer on board that communicated with the external scheduling systems every 1/2 second or less, sending in its current position with a resolution of less than 2 m. The position was measured by small spiral antennas running in the guide track, which also send position information to the scheduling computers at 1,200 bit/s over an inductive loop in the track.

Gasoline Alley, an electric steel-guide rail car ride below, was built together and intimately intertwined, which enhanced ride-to-ride interaction thrill value. Rider safety concerns of the high center of gravity coupled with the method of rider restraints caused it to be re-themed Wacky Soap Box Racers with vehicles now attached in four-car trains, each car seating two riders, strapped in low (nearly straddling the track), surrounded by the close fitting car sides, and the dips and bumps of the track were straightened flat in 1980. Motorcycle Chase/Wacky Soap Box Racers was removed in 1996 for a dueling loop coaster Windjammer Surf Racers and now a launched coaster named Xcelerator takes its place The former Steeplechase Park at Coney Island, New York City, was named for its thrilling Steeplechase attraction, and is perhaps the most famous of this type of coaster. In 2017, S&S; \- Sansei Technologies announced that they would be reviving the Steeplechase coasters with redesigned trains and restraints "S&S-Sansei; Steeplechase Concept".
