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.

Consolidated, as the name suggests, began as a result of the acquisition and combination (that is, consolidation) of a number of pre-existing small bus companies which extended more-or-less radially on routes reaching outward from Lexington throughout the Bluegrass State – to Frankfort and Louisville (and later onward to Owensboro and Henderson and to Evansville in Indiana), Carrollton, Madison (in Indiana), Cincinnati (in Ohio), Maysville, Ashland (and onward for a while to Huntington in West Virginia), Paintsville, Pikeville, Hazard, Harlan, Danville, Richmond, Berea, London, Corbin (and later beyond to Knoxville in Tennessee via Williamsburg in Kentucky and LaFollette in Tennessee), Middlesboro (and later onward to Knoxville on an alternate route via Tazewell and Maynardville, all three in Tennessee), Somerset (and later onward to Chattanooga via Oneida and Dayton while bypassing Knoxville, all four in Tennessee), Bardstown, Columbia, Glasgow, Scottsville, Burkesville, Tompkinsville, Paducah (for a while), and Bowling Green (and in 1927 onward to Nashville in Tennessee). In September, 1928, Guy Huguelet bought a controlling interest in the Greyhound Bus Line Company from Ezra Polhamus and his son, Edward, who had been operating the bus line from Ashland, KY. At that time, Mr. Huguelet was elected president, succeeding Ezra Polhamus, while M.V.Swift of Lexington was elected secretary-treasurer, succeeding Edward Polhamus.

Development Consolidated spread farther to the south and southeast by buying even more existing bus operations, including in 1930 the Union Transfer Company (UTC), which had begun in -24 in the Volunteer State. Union, based in Nashville, Tennessee, provided the CCC Lines with the routes connecting Nashville with Knoxville, Chattanooga, Hopkinsville (in Kentucky), and Florence and Birmingham (both in Alabama), plus a link between Knoxville and Chattanooga (both in East Tennessee).

Among the other acquired bus properties were two related firms in Alabama – the Alabama Bus Company (running from Chattanooga in Tennessee through Birmingham and Montgomery to Mobile, the entire length of the "Heart of Dixie") and the Capital Coaches (running from Birmingham through Montgomery to Dothan), both bought also in 1930.

[In the previous year, 1929, the Old South Coach Lines came into existence to buy a short branch line (with a length of about 59 miles) between Birmingham and Tuscaloosa (both in Alabama) from the same Alabama Bus Company, then promptly extended about 93 more miles from Tuscaloosa to Meridian (in Mississippi); in the next year, 1930, Old South became bought by and merged into the Teche Lines (which in 1934 became renamed as the Teche Greyhound Lines), thus allowing Teche to complete its route between New Orleans (in Louisiana) and Birmingham.]

After the CCC began running through Birmingham, it soon started a direct route between Birmingham and Atlanta (in Georgia) via Anniston (in Alabama) and Tallapoosa (in Georgia), as soon as that part of US highway 78 (US-78) became passable or operable.

The SEG Lines also developed extensive local suburban commuter services based in Atlanta, Birmingham, Louisville, and Nashville.

Relationship with Greyhound From an early date Consolidated operated in conjunction with Greyhound in a cooperative way (with through-ticketing of passengers, through-checking of their baggage, and coordinated connecting schedules, all of which provided advantage to each company along with convenience to their customers).

The CCC sought (among other carriers) the "Greyhound Lines of Georgia", a new and relatively small but significant operation, which by that time had become a single-line company (after initial growth and subsequent paring or pruning), on a route between Chattanooga (in Tennessee) and Jacksonville (in Florida) via Atlanta and Macon (both in Georgia), through the entire length of the Peach State. [In the name of the Greyhound Lines of Georgia, the words "of Georgia" were an integral part of the legal name of the corporate entity, not merely a descriptive phrase.]

That regional Greyhound company in Georgia had started in 1928 as a subsidiary of the Motor Transit Corporation (MTC), the original Greyhound firm, although that subsidiary was then isolated from the rest of the Greyhound empire in that early time in the development of the company's route network – isolated except at its southern end in Jacksonville, which in 1931 the Atlantic Greyhound Lines (called also Atlantic or AGL), another operating company, also reached from the north and northeast along the East Coast.

The Greyhound Lines of Georgia was a result of the work of J.C. Steinmetz, whom the officers of the MTC had sent in 1927 to the Southeast to spearhead the growth of Greyhound in that direction and to provide Greyhound with a gateway for the important (that is, potentially lucrative and therefore profitable) passenger traffic between Florida and the populous Midwest.

{In 1929 the Motor Transit Corporation became renamed as The Greyhound Corporation, and in 1930 the company moved its administrative headquarters from Duluth, Minnesota, to Chicago, Illinois, which had begun to emerge as the major gateway for highway travel between the East and the West. [The firm had already moved its operating headquarters to Chicago.]}

The Greyhound Corporation renamed the Greyhound Lines of Georgia (running between Chattanooga and Jacksonville) as the Southeastern Greyhound Lines and in 1931 sold it to the Consolidated Coach Corporation, with which it made connections in Atlanta and Chattanooga. Consolidated then began operating the SEG Lines along the route between Chattanooga and Jacksonville, thereby making connections (in Jacksonville and Lake City) for various points throughout the Sunshine State via the Florida Motor Lines (FML), which in -46 became renamed as the Florida Greyhound Lines (FGL) and which in 1957 became merged into the Southeastern GL.

Consolidated also made connections in Dothan, Alabama, with the Union Bus Company (not to be confused with the Union Transfer Company based in Nashville), which former Union firm in turn made connections in Tallahassee, Lake City, and Jacksonville with the Florida Motor Lines for points along the Gulf Coast and elsewhere in Florida.

Thus Consolidated connected the Florida market with Greyhound in the Midwest – in Birmingham (and onward to Memphis, Tulsa, Oklahoma City, and beyond), in Evansville (and onward to Saint Louis, Kansas City, Omaha, Denver, and beyond), in Louisville (and onward to Indianapolis, Fort Wayne, South Bend, Chicago, Milwaukee, Minneapolis, and beyond), and in Cincinnati (and onward to Dayton, Toledo, Detroit, Columbus, Cleveland, Akron, Youngstown, and beyond).

A maverick Greyhound affiliate Through the purchase of the SEGL (in 1931), Consolidated acquired the right to use the Greyhound dog trademark, the Greyhound color scheme (blue and white), and the Greyhound and Southeastern names.

Shortly afterward that same year, 1931, with the consent of The Greyhound Corporation, Consolidated began using the name of the Southeastern Greyhound Lines as a brand name, trade name, or service name for its entire operation (not just between Chattanooga and Jacksonville but rather throughout its entire system) and began placing the Greyhound dog, the Greyhound name, and the Greyhound color scheme on all its coaches, and all the drivers and other workers began wearing Greyhound uniforms – even though the legal name of the company continued (albeit temporarily) as the Consolidated Coach Corporation. For that reason (between 1931 and 1936) the coaches bore the names of both Greyhound (in large lettering) and Consolidated (in small sublettering).

In 1936, however, the Consolidated Coach Corporation became renamed as the Southeastern Greyhound Lines, Inc. The home office remained in Lexington, and the employees continued as before.

Thus Southeastern became a maverick or atypical Greyhound company, one of only two major affiliates which sometimes have been called the non-Greyhound Greyhound companies.

[The other was the Overland GL, based in Omaha, Nebraska, which had begun as two related carriers – the Union Pacific (UP) Stages, a highway-coach subsidiary of the Union Pacific (UP) Railroad (also based in Omaha), and the Interstate Transit Lines, another such subsidiary jointly owned by the UP Railroad and the Chicago and North Western (C&NW) Railway.]

In 1938 the Southeastern Greyhound Lines, Inc., became listed for trade on the New York Stock Exchange (the "big board"), as not only the first corporation based in Lexington thus listed but also the first bus-operating company anywhere. [Although The Greyhound Corporation had previously (in 1935) become listed on the big board, that parent firm did not then operate buses at all, for it was still merely a holding company rather than an operating company, while at first the subsidiaries and affiliates conducted the operations.]

The SEGL remained under separate ownership (that is, SEG was an independent corporation under independent ownership, not a division or subsidiary of The Greyhound Corporation) until the end of 1950.

[One subtle but significant consequence of the independent status was that the coaches of those two independent companies bore the full names of the Overland Greyhound Lines and the Southeastern Greyhound Lines, whereas, starting about 1935, the coaches of all the captive Greyhound divisions and subsidiaries bore the collective or abbreviated name of the "Greyhound Lines".]

Southeastern about 1944 introduced one clever twist along with its use of the Greyhound dog (especially as applied to the sides of the coaches), possibly in part a response to the "Battle of Britain" target-like symbol used (during World War II) with the dogs on the sides of the coaches belonging to the divisions and the subsidiaries of the parent Greyhound firm. The SEGL superimposed the dog onto a compass rose in a way which emphasized the letters SE (for southeast). That usage continued until the GM Silversides PD-3751 coaches began to arrive (late in 1947) with the standard dogs without the compass roses, and until the last of the 1948 ACF-Brill IC-41 parlor coaches and the last of the 1949 ACF-Brill C-44 suburban coaches arrived with their dogs with the roses on the sides, and until the last of the ACF and ACF-Brill coaches with the compass roses later in due course became repainted without the roses.
