Merger With Northland GL
In September 1957, in another round of consolidation, The Greyhound Corporation further merged the Great Lakes GL with – not into but rather with – the Northland GL (called also Northland or NGL), a neighboring regional operating company – thereby forming the Central Division of The Greyhound Corporation (called also the Central GL, making the fifth of six uses of that name), the second of four huge new divisions (along with Eastern, Southern, and Western).
The administrative headquarters functions of the Great Lakes GL moved from Detroit to Minneapolis, Minnesota, the home of the Northland GL.
The Northland GL had reached as far north as Sweetgrass, Montana (in Montana) and Winnipeg, Manitoba, as far east as Saint Ignace, Michigan, Milwaukee (in Wisconsin), and Chicago (in Illinois), as far to the south as Chicago (in Illinois), Dubuque (in Iowa), and Omaha (in Nebraska), and as far to the west as Sweetgrass, Great Falls, Helena, and Butte, Montana; it had met (to the west) the Northwestern GL, (to the north) the Western Canadian GL and the Eastern Canadian GL, (to the east and south) the Great Lakes GL and the (second) Eastern GL (formerly the second Central GL and the Pennsylvania GL), and (to the south) the Overland GL.
Thus ended the Great Lakes GL and the Northland GL, and thus began the (fifth) Central GL.
