Changchun Railway Vehicles
The Airport Express line adopts Advanced Rapid Transit (since renamed Innovia Metro) technology from Bombardier Transportation, with a fleet of 10 trains assembled by Changchun Railway Vehicles (CRV, now part of CRRC Corporation) under a technology transfer agreement. The vehicles were based on those used on AirTrain JFK in New York City, with Bombardier providing bogies as well as the electrical, propulsion and brake systems, which were assembled by CRV.
