who found the Dashaveyor concept and decided it would make the basis for a competitive AGT system. Its main advantages in this role were its high speed and its ability to switch among a network of tracks. Most competing AGT systems operated at a fixed speed that was much lower than the Dashaveyor, and normally followed fixed routes. They purchased the company and turned it into a subsidiary, developing the AGT versions in Ann Arbor, Michigan. Conversion to an AGT system was relatively straightforward. The steel wheels were replaced with rubber ones, which ran in a narrow concrete guideway structure instead of the I-beam rails. The guideway was roughly the size and shape of a pedestrian sidewalk, with short vertical extension on either side to form a U-shape. Small horizontal wheels at the front of the cars pressed against the vertical sections and guided the main wheels around corners. Power was provided via a third rail system attached to the top of the right vertical extension (as seen in the direction of travel). The vehicle body was extended upward and generally enlarged to form a van-like structure holding 31 passengers. An image of the vehicle was published in Popular Science in its November 1971 edition in a story about personal rapid transit Each car had three sets of automated doors, entering into a set of facing seats. This divided the internal area into sections; it was not possible to walk the length of the vehicle, nor were there provisions for standing. They were normally operated in trains of two or four cars. One of the earliest major sales efforts for the Dashaveyor AGT was a system for the Dallas/Fort Worth International Airport. Bendix and Varo both received parts of a $1 million grant from the new Urban Mass Transit Administration to study the system. Both bids came in well over the airport's budget, and in the end it was won by the Vought Airtrans. A similar system for Newark International Airport ended when the entire project was put on hold. In 1972, the company displayed the Dashaveyor as one of four major deployments shown at the Transpo '72 show in Washington, D.C. Like the other vendors, Bendix found little third-party interest in the AGT market, and was one of the first vendors to withdraw from the market, inactive by 1975. Toronto Zoo Bendix had found a customer willing to act
