AirTrain JFK uses Bombardier Transportation's Innovia Metro rolling stock and technology.
Similar systems are used on the SkyTrain in Vancouver, Line 3 Scarborough in Toronto, and the Kelana Jaya Line in Kuala Lumpur.
The computerized trains are fully automated and use a communications-based train control system with moving block signals to dynamically determine the locations of the trains.
AirTrain JFK is a wholly driverless system, and it uses SelTrac train-signaling technology manufactured by Thales Group.
Trains are operated from and maintained at a 10-acre (4 ha) train yard between Lefferts Boulevard and Federal Circle, atop a former employee parking lot.
The system originally used pre-recorded announcements by New York City traffic reporter Bernie Wagenblast, a longtime employee of the Port Authority.

The 32 individual, non-articulated Mark II vehicles operating on the line draw power from a 750 V DC top-running third rail.
A linear induction motor pushes magnetically against an aluminum strip in the center of the track.
The vehicles also have steerable trucks that can navigate sharp curves and steep grades, as well as align precisely with the platform doors at the stations.
The cars can run at up to 60 miles per hour (97 km/h), and they can operate on trackage with a minimum railway curve radius of 230 feet (70 m).

Each car is 57 feet 9 inches (17.60 m) long and 10 feet 2 inches (3.10 m) wide, which is similar to the dimensions of rolling stock used on the New York City Subway's B Division.
Trains can run in either direction and can consist of between one and four cars.
The cars contain two pairs of 10-foot-5-inch-wide (3.18 m) doors on each side.
An individual car has 26 seats and can carry up to 97 passengers with luggage, or 205 without luggage.
Because most passengers carry luggage, the actual operating capacity is between 75 and 78 passengers per car.
