Skylink is an automated people mover (APM) system operating at Dallas Fort Worth International Airport (DFW). It is an application of the Innovia APM 200 system and is maintained and operated by Alstom. When it opened in 2005, it was the world's longest airside airport train system.

An automated guideway transit (AGT) or automated fixed-guideway transit or automatic guideway transit system is a type of fixed guideway transit infrastructure with a riding or suspension track that supports and physically guides one or more driverless vehicles along its length. The vehicles are often rubber tired or steel wheeled, but other traction systems including air cushion, suspended monorail and maglev have been implemented. The guideway provides both physical support, like a road, as well as the guidance. An automated line can be cheaper to run than a conventional line, due to the shorter trains and stations.
