Bill Stokes, BART's first general manager, credits Adrien J. Falk, BART's first Board President, for fostering the creative atmosphere that prevailed on the project. He called Falk "a catalyst for spirited, imaginative approaches to engineering challenges. He created a dynamic environment in which creative energy could soar. People could look for quantum leaps in innovation.” Most of the innovations cited by ASME, such as the engineering details in the transbay tube, were not readily visible to the public. However, people did notice the sleek trains. The Adrien Joseph Falk papers (72/39 c) included a "Photographic Record of Progress on Prototype Model for BART."
These photos illustrate what those BART cars could have looked like and show some proud engineers/boosters showing off a BART model.
Quotes taken from “National Historic Mechanical Engineering Landmark,” http://files.asme.org/ASMEORG/Communities/History/Landmarks/1496.pdf, 1997. Falk became director and first board president of BART in 1957, when he was 73 years old. According to the biography in the finding aid for his papers, the San Francisco Board of Supervisors recognized Falk's strong sense of civic responsibility when they proclaimed January 17, 1970, “Adrien J. Falk Day" to honor is contributions to civic life and community welfare.
