Part of: Automated People Movers IV


In October of 1992 American Airlines inaugurated a new people mover service among four stations within its two-terminal complex at the Dallas/Fort Worth Airport (D/FW). Named the `TrAAm,' this new system was actually born out of AIRTRANS, the eighteen-year old system which has been in operation at D/FW since January of 1974. The TrAAm project involved refurbishment of the entire 66-vehicle AIRTRANS fleet, reconfiguration of the fleet for three-car train operations, construction of approximately 6500 feet (1982 meters) of new guideway, construction of four new stations, installation of three new switches, addition of two traction power substations and a complete restructuring of the operating controls and software to accommodate an entirely new routing structure. This paper describes the TrAAm vehicle modification/conversion program which was the first ever conducted on a fleet of automated people mover vehicles. The paper discusses the project approach, the various work elements and presents cost information about the vehicle conversion project.
