early coach concerns. The two Kraemer brothers left the Carolina Coach Company in 1927, then they joined Baskette in his firm in Tennessee. Development In 1928 O.B. Baskette and Al Kraemer incorporated the Tennessee Coach Company, bought the Southern Motor Coach Company (running between Knoxville and Chattanooga), then merged that firm and Baskett's own Safety Coach Company (running between Knoxville and Johnson City) into the new TCC. The State of Tennessee in 1929 issued a joint certificate (of public convenience and necessity) to the TCC and the Union Transfer Company (UTC), based in Nashville, for service between Nashville and Knoxville along US-70, later redesignated in part as US-70S, via Murfreesboro, Woodbury, McMinnville, Sparta, Crossville, Rockwood, and Kingston. [In 1930 the Consolidated Coach Corporation (Consolidated, CCC, or the CCC Lines), based in Lexington, Kentucky, bought the UTC; in 1931 Consolidated adopted the brand name, trade name, or service name of the Southeastern Greyhound Lines (Southeastern, SEG, SEGL, or the SEG Lines); in 1936 the Consolidated firm became renamed as the Southeastern Greyhound Lines (GL).] The Tennessee Coach Company in 1929 extended its Johnson City line to Bristol (on the state line between Tennessee and Virginia) and in 1930 to Bluefield (on the state line between Virginia and West Virginia; in 1938 it added service to Atlanta, Georgia, both from Knoxville and from Chattanooga (although along rural backwoodsy routes through lightly populated areas, because Greyhound already ran between Chattanooga and Atlanta through more populous areas in north Georgia via Rome, Dalton, and Calhoun). The TCC also provided extensive local commuter service from Knoxville to Kingston, Rockwood, Harriman, Oliver Springs, and (especially during World War II) to Oak Ridge (still sometimes called the Secret City). [Oak Ridge was the site of the headquarters of the top-secret Manhattan Project, which in 1945 produced the world's first nuclear weapons.] A sharing arrangement The Tennessee Coach Company and the other carrier – first the UTC, later the CCC, even later the Southeastern GL – shared their joint certificate (for the route between Nashville and Knoxville) in an unusual way: One carrier ran in one direction on any given scheduled trip, then the other carrier ran in that direction on that same sked the next day, and vice versa. That is, they ran in opposite directions, and they changed directions each day. That plan continued until 1956, when the TCC joined the National Trailways association. With the
