between Chicago and Kansas City via Saint Louis (the two latter in Missouri), and which became renamed as the Pickwick-Greyhound Lines, after the Pickwick Corporation bought a one-half ownership interest in that firm (hence the hyphenated name). Later the route segment between Saint Louis and Kansas City became transferred to the Southwestern GL, and the segment between Chicago and Saint Louis became transferred to the Illinois GL (then to the Central GL, then eventually to the Great Lakes GL).] In 1929 the MTC became renamed as The Greyhound Corporation (with an uppercase T, because the word "the" was an integral part of the legal name of the corporate entity). The GLI of Indiana and the GLI of Ohio developed additional routes, mostly by buying existing properties. During the early years of the growth of the Greyhound empire, the GLI of Indiana performed an important function, by operating a number of significant routes before they became transferred to other operating companies. The first Central GL In 1930 The Greyhound Corporation, the parent Greyhound firm, formed two new regional companies – the Pennsylvania Greyhound Lines (GL) and the (first) Central GL. The purpose of the Pennsylvania GL was to provide an entity in which the Pennsylvania Railroad (PRR) soon bought a minority interest, a subsidiary in a territory which coincided with the territory of the railway firm – so that the rail company could supplement its train service and substitute bus service in place of some of its unprofitable and marginally profitable passenger trains. Greyhound then transferred the routes of the GLI of Indiana and the GLI of Ohio to the new companies. The east-west routes went to the Pennsylvania GL, as did the other ones paralleling other lines of the PRR. The remaining routes [that is, those between Evansville and Indianapolis and between Detroit and Cincinnati and onward to Louisville (in Kentucky)] went to the (first) Central GL. The GLI of Indiana and the GLI of Ohio then went out of existence. Ohio GL The (first) Central GL in 1935 (five years later) became renamed as the Ohio Greyhound Lines (completely different and separate from the GLI of Ohio, which had gone out of existence in 1930) – to allow Greyhound to reassign the name Central to a new subsidiary, in the Midwest and the Northeast, one in an area which coincided with the territory of another major railway company, the
