Aluminum Extrusions are used extensively on, in and under the Automated People Mover (APM). Called the AeroTrain at Washington Dulles International Airport, the trains have been in use since 2010. Riding on 28,000 feet of extruded aluminum power rails, the 29 cars and station include 128 door headers and thresholds made of extruded aluminum. The APM reaches speeds of up to 50 miles per hour on rubber wheels that face less wear and tear thanks to lightweight, structurally strong extruded aluminum high-powered rails, which played a crucial role in the Dulles APM system. Similar systems are in place at the Dallas-Ft. Worth (DFW) airport and San Francisco International Airport.
