and Kingsport) to the Tennessee Coach Company. Thus the TCC began running between Knoxville and Bristol along -11W, the leased parallel route, as well as -11E, its own original route. Later in 1932 Hill and Gilmer bought the one-third interest of Huguelet in the OD Stages, then they merged OD into their Atlantic GL. The TCC continued to run the leased Old Dominion segment (between Knoxville and Bristol) along US-11W as well as its own original parallel route along -11E. It took part in through-schedules (interlined pool operations) – that is, the use of through-coaches on through-routes running through the territories of two or more operating companies – in cooperation with the Atlantic GL, the Dixie GL, and the Southeastern GL – including those between Birmingham, Alabama, and Bristol and between Memphis, Tennessee, and Washington. It did so until 1956, when the TCC joined the National Trailways trade association, and when the TCC returned its leased right to that segment to the Atlantic GL (as the successor in interest of the OD Stages) – as a part of the deal related to the dissociation of the TCC from Greyhound. Afterward the TCC continued running between Knoxville and Bristol, but only along its own original route on US-11E. Sale of TCC In 1960 the Tennessee Coach Company became sold to a new firm (created specifically to buy the TCC), named as the Tennessee Trailways, Inc., owned in three equal shares by three other Trailways member companies. The investors were the Virginia Stage Lines (the Virginia Trailways), the Smoky Mountain Lines (the Smoky Mountain Trailways), and the Continental Tennessee Lines (a Trailways concern which ran in part between Nashville and Knoxville along US-70N via Lebanon, Carthage, Cookeville, and Crossville. [That last firm was a wholly owned subsidiary of the Continental Southern Lines, based in Alexandria, Louisiana. The two latter firms were members of the Transcontinental Bus System (using the brand name of the Continental Trailways), which was the largest member company in the National Trailways association.] The TCC retained its old brand name until 1976 despite the sale. In 1966 the Transcontinental Bus System (operating as the Continental Trailways), based in Dallas, Texas, bought most of the large Trailways member companies along the Atlantic Seaboard. Those included were the Safeway Trails (the Safeway Trailways), the Virginia Stage Lines (the Virginia Trailways), the Queen City Coach Company (the Queen City Trailways), and the
