The Southeastern Greyhound Lines (called also Southeastern, SEG, SEGL, or the SEG Lines), a highway-coach carrier, was a Greyhound regional operating company, based in Lexington, Kentucky, USA, from 1931 until 1960, when it became merged with the Atlantic Greyhound Lines, a neighboring operating company, thereby forming the Southern Division of The Greyhound Corporation (the parent Greyhound firm), called also the Southern Greyhound Lines.
The Southeastern Greyhound Lines (GL) started in 1926 as the Consolidated Coach Corporation (called also Consolidated, CCC, or the CCC Lines) – with the participation of Guy Alexander Huguelet, a native of Charleston, South Carolina, and a lawyer of German and French-Swiss descent, who from the outset served variously as the legal counsel, the general manager, the vice president, and (mostly) the president. [Huguelet had begun his career in transportation by working (for six years, starting at age 15) in several clerical jobs for two railroad companies (at different times), the Southern Railway System and the Atlantic Coast Line, in and around Charleston and in Charlotte, North Carolina.]
In 1926, the same year in which Guy Huguelet and his associates in Lexington formed the Consolidated Coach Corporation, Carl Eric Wickman, Orville Swan Caesar, and their associates in Duluth, Minnesota, formed the Motor Transit Corporation, which in 1929 was renamed as The Greyhound Corporation.
