While waiting for the mandatory approval (for the investment, the acquisitions, and the mergers pertaining to the NEGL) of the federal Interstate Commerce Commission (ICC), the EGL of New England (in operation since 1930) and the New England Transportation Company began to coordinate their scheduled trips (between Boston and New York City) with each other, and each company began to accept the tickets of the other.
The NEGL acquired also (likewise from the NET Company) the Berkshire and Victoria firms (each of which ran between Boston and New York City on an inland route via Hartford).
[After those acquisitions by the NEGL, Berkshire, Victoria, Quaker, and Old Colony all ceased to exist, although the NET Company continued to operate on several other routes (albeit on shorter ones) in Connecticut, Rhode Island, and Massachusetts, until 1958.]
On the last day of October 1950 The Greyhound Corporation bought back the one-half interest of the New Haven Railroad in the New England GL.
In 1953 the New England GL bought the International Coach Lines (ICL), based in Rumford, Maine, which ran between two points in Canada – Montréal, Québec, and Saint John, New Brunswick – along a route (a shortcut of sorts) mostly through northern New England – via Stanhope (in Québec), Norton (in Vermont), Colebrook, Lancaster, and Gorham (all three in New Hampshire), Rumford, Bangor, Lincoln, and Calais (all four in Maine), and Saint Stephen (in New Brunswick).
Thus The Greyhound Corporation (through the NEGL as a wholly owned subsidiary) acquired and began to operate its first MCI coaches in the USA.
In 1987 The Greyhound Corporation (the original parent Greyhound firm), which had become widely diversified far beyond transportation, sold its entire highway-coach operating business (its core bus business) to a new company, named as the (second) Greyhound Lines, Inc., also called the (second) GLI, based in Dallas, Texas – a separate, independent, unrelated firm, which was the property of a group of private investors under the promotion of Fred Currey, a former executive of the Continental Trailways (later renamed as the Trailways, Inc., also called TWI, also based in Dallas), which was by far the largest member company in the Trailways association.
The lenders and the other investors of the GLI ousted Fred Currey as the chief executive officer (CEO) after the firm went into bankruptcy in 1990.
