AeroTrain, the planning for which started a decade ago and digging and construction work took eight years, was unveiled as part of a $3 billion renovation. Its implementation will help passengers get to their gates more quickly.
This new underground train spans nearly four miles long, and its 29 cars run 42 miles per hour. The estimated wait time for a train should be less than two minutes, and the proposed time between gates should last just over a minute.
The airport has also planned for major expansion. Two new parking garages, a fourth runway, a new control tower, and moving walkways that bring travelers within terminals A and B gates are all in the works. The airport is also expanding the Midfield Concourse, which will be home to redeveloped gates C and D.
