Skylink is an automated people mover system in operating at Dallas-Fort Worth International Airport (DFW). It is an application of the Bombardier Innovia APM 200 system manufactured by Bombardier Transportation, and is the world's largest airport train system.^[1] Sixty-four Skylink trains are in service at DFW.

Skylink was developed as a replacement for the Airtrans APM, the airport's original people mover system that connected airport facilities and parking lots. As DFW became a large connecting hub for flights, Airtrans (which was slow and followed a uni-directional loop) was inefficient in moving passengers.^[2]

The system was opened in Spring 2005 and is completely automated. Skylink trains run every two minutes and travel at speeds up to 35–37 mph (56–60 km/h).^[3][4][5]

The Skylink system is airside at DFW, serving passengers connecting between flights. There is no need to leave security and be re-screened when switching terminals. The system is only accessible airside and cannot be accessed by those not arriving at DFW or who have not cleared security. Arriving International passengers (who are not pre-cleared; e.g. Canada) who are connecting clear US CBP formalities and are then security screened before access to the terminals. Departing international passengers connecting from domestic or pre-cleared international flights do not need to be re-screened.

The longest trip between farthest stations is 9 minutes with an average 5 minute journey. This allows most passengers to make a connection from any one flight to another in around seven minutes, not including walking time to and from the stations.^[6]

The concrete and steel guideway for Skylink was constructed above the terminals on 375 columns in a 4.8 mile long bi-directional loop. The inner track travels clockwise and the outer track travels counter-clockwise. Each of the five current terminals contains 2 stations which are accessed on the secure (air) side. Unlike the previous Airtrans APM system, Skylink only connects terminals and does not travel to the airport's parking lots or rental car facility. The stations contain four sets of doors on each platform, with only the front 2 currently in operation pending future increased demand. Two more stations can be constructed for a sixth terminal if it is built.

The Innovia APM 200 technology is also used at London Heathrow International Airport's T5 terminal. As well as the upcoming PHX Sky Train. ^[3]

A people mover or automated people mover (APM) is a fully automated, grade-separated mass transit system.

The term is generally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks, but is sometimes applied to considerably more complex automated systems.

The term was originally applied to three different systems, developed roughly at the same time. One was Skybus, an automated mass transit system prototyped by the Westinghouse Electric Corporation beginning in 1964.^[1][2][3] The second, alternately called the People Mover and Minirail, opened in Montreal at Expo 67. Finally the last, called PeopleMover or Goodyear PeopleMover, was an attraction sponsored by the Goodyear Tire and Rubber Company which opened at Disneyland in 1967.^[4] Now, however, the term "people mover" is generic, and may use technologies such as monorail, duorail, automated guideway transit or maglev. Propulsion may involve conventional on-board electric motors, linear motors or cable traction.

Generally speaking, larger APMs are referred to by other names. The most generic is "automated guideway transit", which encompasses any automated system regardless of size. Some complex APMs deploy fleets of small vehicles over a track network with off-line stations, and supply near non-stop service to passengers. These taxi-like systems are more usually referred to as personal rapid transit (PRT). Larger systems, with vehicles with 20 to 40 passengers, are sometimes referred to as "group rapid transit" (GRT), although this term is not particularly common. Other complex APMs have similar characteristics to mass transit systems, and there is no clear cut distinction between a complex APM of this type and an automated mass transit system.

History[link]

Never-Stop Railway[link]

One of the first automated systems for human transportation was the screw-driven 'Never-Stop-Railway',^[5][6] constructed for the British Empire Exhibition at Wembley, London in 1924. This railway consisted of 88 unmanned carriages, on a continuous double track along the northern and eastern sides of the exhibition, with reversing loops at either end.

The carriages ran on two parallel concrete beams and were guided by pulleys running on the inner side of these concrete beams^[7][8], and were propelled by gripping a revolving screw thread running between the tracks in a pit ; by adjusting the pitch of this thread at different points, the carriages could be sped up, or slowed down to a walking pace at stations, to allow passengers to join and leave. The railway ran reliably for the two years of the exhibition, and was then dismantled.^[9]

Small sections of this track bed, and a nearby heavy rail track bed, have been proposed for reuse.^[10]

Goodyear and Stephens-Adamson[link]

This unreferenced section requires citations to ensure verifiability.

Late 1949, Mike Kendall, Chief Engineer and Chairman of the Board of Stephens-Adamson Mfg. Co asked Al Neilson, an engineer in the Industrial Products Division of Goodyear Tire and Rubber Co., if Goodyear had ever considered working on People Movers. He felt that with Goodyear’s ability to move materials in large quantities on conveyor belts they should consider moving batches of people.

Four years of engineering design, development, and testing led to a joint patent being issued for three types of people movers which had been named Speedwalk, Speedramp, and Carveyor. Goodyear would sell the concept and Stephens-Adamson would manufacture and install the components.

A speedwalk consisted of a flat conveyor belt riding on a series of rollers, or a flat slippery surface, moving at 1.5 mph (2.4 km/h). (approximately half the speed of walking) the passengers would walk onto the belt and could stand or walk to the exit point. They were supported by a moving handrail. Customers were expected to be airport terminals, ballparks, train stations, etc. Today several manufacturers produce similar units called moving walkways.

A Speedramp was very similar to a Speedwalk but it was used to change elevations; up or down a floor level. This could have been accomplished by an escalator, but the Speedramp would allow wheeled luggage, small handcarts etc. to ride the belt at an operating cost predicted to be much lower than escalators or elevators. The first successful installation of a Speedramp, spring of 1954, was in the Hudson and Manhattan RR Station in Jersey City to connect the Erie RR to the Hudson & Manhattan Tubes. This unit was 227 feet (69 m) long, rose up 22 feet (6.7 m) on a 15 degree grade and only cost $75,000.

A Carveyor consisted of many small cubicles or cars carrying ten people riding on a flat conveyor belt from point A to point B. The belt rode on a series of motorized rollers. The purpose of the motorized rollers was to facilitate the gradual acceleration and deceleration speeds on the conveyor belt and over come the tendency of all belts to stretch at start up and during shutdown. At point “A” passengers would enter a Speedwalk running parallel to the belts and cars of the Carveyor. The cars would be moving at the same speed as the Speedwalk; the passengers would enter the cars and be seated, while the motorized rollers would increase the speed of the cars up to the traveling speed (which would be preset depending on the distance to be covered). At point B Passengers could disembark and by means of a series of flat slower belts (Speedwalks) go to other Carveyors to other destinations or out to the street. The cars at point B would continue on rollers around a semicircle and then reverse the process carrying passengers back to point A. The target installation was to be the 42nd Street Shuttle in NYC between Times Square and Grand Central station. The first mention of the Carveyor in a hardback book was in "There's Adventure in Civil Engineering", by Neil P. Ruzic. The book was one of the 11 books that Popular Mechanics published in the early to mid 1950s in their "Career" series. In the book the Carveyor was already installed and operational in downtown Los Angeles.

Colonel Sydney H. Bingham, Chairman of the New York City Board of Transportation, had several meetings with a group of architects who were trying to revamp the whole New York City Subway system in the heart of town to connect Penn. Station, Madison Square Garden, Times Square, Grand Central and several new office complexes together. Several of these architects were involved in other programs and in later years many variations of the Carveyor people movers developed.

In November 1954 the New York City Transit Authority issued an order to Goodyear and Stephens-Adamson to build a complete Carveyor system between Times Square and Grand Central. A brief summary and confirmation can be found in Time magazine on November 15, 1954. under the heading “Subway of the Future”. The cost was to be under $4 million, but the order was never fulfilled due to political difficulties.

Chocolate World in Hershey Pa., Disneyland in California, and Disney World in Florida are among many other locations that have used variations of the Carveyor concept. If You Had Wings used the Omnimover.

Other developments[link]

The term 'people mover' was used by Walt Disney, when he and his Imagineers were working on the new 1967 Tomorrowland at Disneyland. The name was used as a working title for a new attraction, the PeopleMover. According to Imagineer Bob Gurr, "the name got stuck," and it was no longer a working title.^[11]

Starting in the late 1960s and into the 1970s, people movers were the topic of intense development around the world. Worried about the growing congestion and pollution in downtown areas due to the spread of cars, many countries started studying mass transit systems that would lower capital costs to the point where any city could afford to deploy them. Most of these systems used elevated guideways, which were much less expensive to deploy than underground tunnels. However, elevating the track causes problems with noise, so traditional steel-wheel-on-rail solutions were rare as they squealed when rounding bends in the rails. Rubber tired solutions were common, but some systems used hovercraft techniques or various magnetic levitation systems.

Two major government funded APM projects are notable. In Germany, Mannesmann Demag and Messerschmitt-Bölkow-Blohm developed a system known as Cabinentaxi during the 1970s. Cabinetaxi featured small cars with from four to eight seats that were called to pick up passengers on-demand and drove directly to their destination. The stations were "offline", allowing the cabs to stop by moving off the main lines while other cars continued to their destinations. The system was designed so the cars could be adapted to run on top or bottom of the track (but not easily converted from one to the other), allowing dual-track movements from a single elevated guideway only slightly wider than the cars. A test track was completed in 1975 and ran until development was completed in 1979, but no deployments followed and the companies abandoned the system shortly thereafter.

In the U.S., a 1966 federal bill provided funding that led to the development of APM systems under the Downtown People Mover Program. Four systems were developed, Rohr's ROMAG, LTV's AirTrans, Ford's APT and Otis Elevator's hovercraft design. A major presentation of the systems was organized as TRANSPO'72 at Dulles Airport where the various systems were presented to delegations from numerous cities in the US. Prototype systems and test tracks were built during the 1970s. One notable example was Pittsburgh's Skybus, which was proposed by the Port Authority of Allegheny County to replace its streetcar system, which, having large stretches of private right of way, was not suited for bus conversion. A short demonstration line was set up in South Park and large tracts of land were secured for its facilities. However, opposition arose to the notion that it would replace the streetcar system. This, combined with the immaturity of the technology and other factors, led the Port Authority to abandon the project and pursue alternatives. By the start of the 1980s most politicians had lost interest in the concept and the project was repeatedly de-funded in the early 1980s. Only two APMs were developed as a part of the People Mover Program, the Metromover in Miami, and the Detroit People Mover.

Although these government-funded systems were generally considered failures, several APM systems developed by other groups have been much more successful. Notable among these systems are the Docklands Light Railway deployed in London, while the French Véhicule Automatique Léger and the Canadian Bombardier ART have both won developments around the world. The Vancouver SkyTrain system is the largest fully automated metro system in the world, with over 60 km of track. These systems are on the "heavy" end of the APM scale. Lighter systems with shorter tracks are widely deployed at airports; the world's first airport people mover was installed in 1971 at Tampa International Airport in the United States. APMs have now become common at large airports and hospitals in the United States.

Driver-less metros have become common in Europe and parts of Asia. The economics of automated trains tend to reduce the scale so tied to "mass" transit (the largest operating expense is the driver's salary, which is only affordable if very large numbers of passengers are paying fares), so that small-scale installations are feasible. Thus cities normally thought of as too small to build a metro (e.g. Rennes, Lausanne, Brescia, etc.) are now doing so.

On September 30, 2006, the Peachliner in Komaki, Aichi Prefecture, Japan became that nation's first people mover to cease operations.

Rural and suburban transit[link]

Pillar-track Regional People Mover

The Pillar-track Regional People Mover is a concept of a People Mover system, that is optimized for rural and suburban areas with lower population density. The aim of the system is to provide short intervals and appropriate riding and waiting times (including changing between lines) outside of urban areas too.^[12]
