History

The AGTS project was announced publicly in October 1992 at a cost of $84 million. The initial system consisted of 16 cars that were paired together in groups of four to traverse the length of the tunnel. The cars themselves ride on rubber wheels and roll along a concrete track. Additionally, crossover tracks exist between each station, so traffic can be routed around stalled or disabled trains if necessary.

Six more vehicles were added to the system by 1995, and an additional five were added in 2001. Today, the fleet consists of 31 Bombardier Innovia APM 100 vehicles, which have a maximum capacity of 100 passengers. Trains generally run at 1.5 minute intervals during peak times resulting in an 11 minute travel time from end to end.

Layout and Operation

Located within the secure areas of the airport, the AGTS utilizes two mile-long tunnels traveling underneath the aircraft taxiways. Four stations exist, serving each airside concourse (Concourses A, B, and C) and the Terminal (which serves Ground Transportation and Baggage Claim). While it is possible to walk from the main terminal to Concourse A via a pedestrian bridge over the taxiway, the train is the only way for the public to access Concourses B and C.

, when a train arrives at the Terminal, the outboard doors open first to allow arriving passengers to exit. The inboard doors then open, allowing departing passengers to board. Currently, all trains use the west platform in the Terminal station, and the east platform is not used for passenger service, and is only occasionally used to store non-operating trains. At the Terminal station, trains reverse direction, and use a switch at a crossover located just north of the station to switch into the northbound tunnel.

The system also includes a maintenance facility, which is located just beyond the Concourse C station.

Audio

The AGTS features an audio system which deliver station information, as well as arrival and departure information to passengers on the trains and platforms. The audio utilizes pre-recorded messages that are delivered by well known voice talent from the Denver area, and are each preceded by a variety of short musical sound effects. The voices and sound effects were recorded by Denver sound artist Jim Green, and they make up one of the airport's public art installations known as "Train Call." Jim Green is also known for recording the audio for the singing sinks in the restrooms at the Denver Art Museum

 delivers a "Welcome to Denver" greeting that plays prior to arriving at the Terminal and Baggage Claim station. His welcome includes portions in both Spanish and English. The current sound effects feature a contemporary music theme, and include sounds from pianos, synthesizers, and electric guitars. The current audio debuted in June of 2007.

With two separate voices, the stations are configured so that one voice delivers information for trains on one side of the platform, while the other voice delivers information for the other side. The trains are configured so that the voice alternates between each of the train's four cars, so that one voice is installed on the first and third cars, while the other voice is installed on the second and fourth cars. Mayor Vidal's voice delivers the "Welcome to Denver" greeting regardless of which voice is installed on the individual car. Each of the announcements is preceded by its own individual sound effect. There are even separate sound effects for the same message, depending on which voice delivers it. The exception to this is the message that announces that the doors are closing, which always has the same sound effect since it is a warning message.

Originally, the audio featured the voices of local radio broadcaster Pete Smythe and former KCNC-TV

." The original audio had been used on the system since the airport's opening in 1995 and remained unchanged for 12 years, primarily due to the status of being a public art installation. The original audio was ultimately replaced due to various changes made at the airport since its opening. The most noticeable change made to the messages themselves was the reference to the concourse stations. The original audio announced "Please hold on. This train is approaching Concourse A," where it now says "Hold on please. We are approaching the station for all 'A' Gates." Station signage was also changed to reflect this. This change was made since some people found the term "concourse" confusing. Some information regarding Baggage Claim monitors in the Terminal station also caused confusion and needed to be removed from the messages, since the monitors themselves were removed from the station years prior. The "Welcome to Denver" greeting as added to the audio along with the current audio in 2007. Although, it originally featured the voice of then-Mayor John Hickenlooper

Tunnel Artwork

The train system's tunnels are home to two of the airport's visual art exhibits. These art installations were created since nearly one percent of the total budget for the construction of Denver International Airport

 was dedicated to artwork. The artwork interacts with the passing trains and can be viewed through the train's windows as they travel through the tunnels.

Kinetic Light Air Curtain

The northbound tunnel features an art exhibit known as the "Kinetic Light Air Curtain." Designed by Antonette Rosato and William Maxwell, the exhibit includes 5,280 propellers mounted on the wall. The propellers are accented with blue fluorescent light, and wind from the trains causes some of them to spin as they pass by. The number of propellers represents the number of feet Denver (the mile-high city) is located above sea level. Also, the total number of blades of all of the propellers combined represents the height of Colorado's tallest fourteener

, which is 14,440 feet tall. Contrary to common belief, the propellers do not generate any electricity for the trains or any part of the airport, and are strictly decorative.

Deep Time/Deep Space, a Subterranean Journey

The southbound tunnel contains the exhibit "Deep Time, Deep Space: A Subterranean Journey." Designed by Leni Schwendinger, this art display primarily consists of over 5,000 feet of colored reflective metal strips arranged into a variety of images. Various other items, sheet metal cut-outs of pick axes and hammers stand out from the tunnel walls to accent the scenes. The exhibit gradually transitions from displaying examples of older technology to newer space-age technology. The art is lighted by an advanced lighting system, which is activated by photoelectric sensors which detect passing trains. The overall work is inspired by Colorado's industrial and mining history.

Failure

While the AGTS is a highly reliable system, one major system failure took place on April 26, 1998. A routing cable in the train tunnel was damaged by a loose wheel on one of the trains, cutting the entire system's power and shutting it down. The entire system was out of service for about seven hours, so a fleet of thirty shuttle buses had to be deployed to transport passengers between the concourses since there are no pedestrian walkways connecting to Concourses B and C.

, DIA's largest airline (who operates out of Concourse B), reported that about 30 percent of their flights and about 5,000 passengers were affected by the failure. The day of the failure is now referred to as "Black Sunday" by airport personnel.

. The novel's antagonist, who flies into DIA, enjoys the musical sound effects that precede the announcements as he travels from his arrival gate to the terminal on the train. The novel states that the antagonist was "smiling all the same at the crazy bursts of jug-band music that preceded the station announcements." The novel references the original sound effects which accompanied the original Pete Smythe and Reynelda Muse announcements.
