Getting around Dulles International Airport is about to get high-tech.
On Monday, Airport officials will show off their new $1.5 billion AeroTrain system that will be used to shuttle travelers from the terminal to their gate. The AeroTrain will replace most of the airports old buses known as "mobile lounges."
The new underground train system will have 29 cars and an average wait time of less than two minutes. It will then take just 72 seconds for passengers to be transported from the main terminal to the concourses.
The airport has not said exactally when the AeroTrain will open to the traveling public. Airport officials have previously said they want the system up and running this month. The system was supposed to debut earlier, but it failed some initial tests.
