Two State of the Art transit cars are now undergoing testing at the UMTA test facility at Pueblo. Next month the cars will be moved to begin a series of revenue service tests. These cars represent the first phase of a three year program. Phase two will attempt to produce a better transit car, constrained only by 600 volt DC power, standard track gauge, and the clearance envelope of five transit systems. Systems manager Boeing-Vertol has five tasks: observe the prototype car program of BART, manage production of the state of the art cars, manage design competition leading to Advanced Concept Train ACT-1 cars, manage the ACT-2 component development program to move from first generation ACT-2 cars to second generation ACT-3 cars, and plan for ACT-3 revenue demonstration. There are two versions of the state of the art car, a 64 seat version and a 72 seat version. The carbodies are stainless steel. The lightweight trucks use air bellows and eliminate metal to metal contact from the car body to the rail. In tests, the interior noise level at 40 mph was 63 db. Each truck is fitted with a pair of 175 hp DC traction motors. Solid state chopper propulsion is used. The car builder, St. Louis Car, and the truck supplier, GSI Castings Division, are both being liquidated. The cars are air conditioned.
