DFW Skylink

Skylink is an automated people mover (APM) system operating at Dallas Fort Worth International Airport (DFW). It is an application of the Innovia APM 200 system and is maintained and operated by Alstom. When it opened in 2005, it was the world's longest airside airport train system (AirTrain JFK, which operates landside, is longer).

History

Skylink was developed as a replacement for the Airtrans (part of which was later operated as American Airlines' TrAAin System), the airport's original people mover system that connected airport facilities and parking lots. It served the airport for 31 years from 1974 to 2005 and transported a quarter of a billion passengers between DFW's then four terminals and employee facilities, logging a total of over the lifetime of its fleet. As DFW became a large connecting hub for flights, Airtrans was noted for being slow with its top speed of and following a uni-directional counter-clockwise loop located inside security for Terminals A, B, and C and outside security to other areas, was inefficient in moving passengers. The system was decommissioned soon after Skylink opened as a modern replacement and the old guideways were left in place throughout the airport.

Skylink guideway construction began in the fall of 1999 and took place with limited interruption of aircraft traffic. Contractors worked during overnight hours for 3 years – when airline gates were unused – arriving on site, completing work and removing equipment each morning before returning gates to an airline.

The system made its public debut on June 25, 2004, where it then began a rigorous testing period. It was opened to the public on May 21, 2005, and is completely automated. Skylink trains run every two minutes and travel at speeds up to .

In 2015, after a decade of service, Skylink had transported over 141 million people and traveled over .

Operations

The Skylink system operates airside at DFW, mostly serving passengers connecting between flights, and is inaccessible to those who have not cleared security.

Skylink operates trains 24 hours a day, 365 days a year. The system is double-tracked and both tracks are operational between 5 am and midnight. Between midnight and 5 am, one track may be taken out of operation to allow for maintenance. The system has crossovers between the Terminal D stations and the Terminal E stations. There are also pocket tracks in the sections of the guideway that cross International Parkway.

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. The train supports a minimum airline connection time of 30 minutes.

The Skylink system uses a total of 64 Innovia APM 200 vehicles, coupled together into two car trains. Each Skylink vehicle can accommodate up to 69 passengers and their carry-on luggage. The Innovia APM 200 technology is also used at London Heathrow Airport's Terminal 5 as well as the PHX Sky Train.

Structure

The concrete and steel guideway for Skylink, elevated at an average of , was constructed above the terminals on 375 columns in a bi-directional loop. The inner track travels clockwise and the outer track travels counter-clockwise.

Each of the five terminals contains two 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 for entrance and exiting of passengers. Two more stations can be constructed for a future Terminal F if it is built.
