The State-of-the-Art Car (SOAC) was a
Design and development
Around 1970, the
The
The SOAC was built to meet the loading gauge of existing rapid transit systems in
The two demonstrator cars were built with two different configurations: "Lo-Density" with a total capacity of 220 passengers per car, and "Hi-Density" with a 300-passenger capacity.
Testing
The SOAC was first tested at the High Speed Ground Test Center in Pueblo, Colorado.[3] On August 11, 1973, the test train collided with a freight car due to a mis-set switch, killing the operator.[8] The collision focused additional attention on the safety of the SOAC design.[9]
After the initial testing, the SOAC set toured six rapid transit systems in five United States cities for additional testing and public rides.
Revenue service began on the
The SOAC next operated on the
The SOAC was well received by the public, particularly due to the quiet operation and air conditioning, as well as by the train operators, who found it easy to control.[7] The operating agencies had more mixed reactions; only some found it useful.[17] After the SOAC and the mixed results of the US Standard Light Rail Vehicle program, UMTA did not pursue further vehicle designs, but instead focused on subsystem research. A number of design elements from the SOAC – including acoustic design, air-ride suspension, chopper propulsion controls, and traction motor ventilation – were incorporated on future rolling stock designs by numerous agencies.[7][14]
The SOAC cars were stored at Boeing Vertol until May 1979, when one was shipped to the Budd Company and one to Pueblo, where they were used for additional subsystem testing.[7][3] The two-car demonstrator was acquired by the Seashore Trolley Museum in Kennebunkport, Maine as a static display in 1989 and has remained there since.[18][19]
