Denver International Airport dismantles failed automated baggage system

The automated baggage handling system at Denver International Airport, which began operations in 1995, was completely dismantled in 2005 after a decade of operational struggles. Originally designed to reduce baggage transfer times to under 20 minutes across the 53-square-mile facility, the $193 million project was awarded to BAE Automated Systems.

The system, which featured a 30-kilometer underground tunnel network, 5,000 optical sensors, and thousands of rail vehicles, faced severe technical failures during testing and operation. Issues included vehicle collisions, luggage falling off tracks, and damaged suitcases. These malfunctions caused a 16-month delay in the airport's opening, resulting in daily costs of approximately $1 million to $1.1 million in interest and infrastructure expenses.

Ultimately, the total cost of the delay was estimated between $500 million and $560 million. The system was never fully implemented as intended; it functioned in only one terminal for departing flights rather than connecting all three main concourses. Following the withdrawal of the only airline using the system due to high maintenance costs, the airport reverted to traditional manual handling and decommissioned the automated infrastructure.
