  • A new four-car station to serve Lot DD, Long Term Parking Garage No. 2 and the Airport Hotel.

  • Design, installation, testing, and commissioning of related AirTrain Operating System upgrade work and an upgrade from the 2001-era Train Control System to a new technology Line-of-Sight Train Control System for the entire AirTrain operating system.
