AeroTrain is a 3.78-mile (6.08 km) people mover system at Washington Dulles International Airport in Dulles, Virginia. It started operations on January 26, 2010. The system mostly replaced the mobile lounges that transport passengers from the concourses to the Main Terminal. The system utilizes 29 Mitsubishi Heavy Industries Crystal Mover vehicles.
The Aerotrain runs 4 three-car trains from 5:00 AM to around 3:00 PM from which seven three-car trains run from 3:00 PM until 11:00 PM. From midnight to 5 AM there are usually two three-car trains but sometimes only one three-car train. There are supposed to be no more than two minutes between trains, and trains transport passengers to the concourses in about two minutes, at 40–42 miles per hour (The mobile lounges travel about fifteen miles per hour).
