The ExpressTram is an automated people mover system operating at Detroit Metropolitan Wayne County Airport, in Romulus, Michigan, USA.

Detroit Metro Airport serves as the second- or third-largest hub for Delta Air Lines, after Atlanta and sometimes after Minneapolis-St. Paul (depending on schedules).

Plans were announced for the McNamara Terminal in 1996 by Wayne County and Northwest Airlines, who operated their largest hub in Detroit at the time.

Northwest merged with Delta Air Lines in 2010, who continues to operate the Detroit hub.

Despite the merger, the trams have retained their red color, but new Delta logos replace the Northwest ones.

The system operates 21 feet (6.4 m) above the main floor, and it consists of two cable-driven trams that ride upon an air-cushion, similar to a hovercraft.
