The Capitol Greyhound Lines (GL) came into existence in November 1930, as a joint venture (owned in two equal shares) by the Blue and Gray (B&G) Transit Company and The Greyhound Corporation to operate a single new main line along U.S. Route 50 between Washington, DC, and Saint Louis, Missouri, via Winchester, Virginia; Clarksburg and Parkersburg, West Virginia; Chillicothe and Cincinnati, Ohio; Bedford and Vincennes, Indiana; and Olney and Salem, Illinois.
The CpGL took part in only one interlined through-route (using pooled equipment in cooperation with one other carrier) – that is, the use of through-coaches on a through-route running through the territories of itself and one other company – with the Red Star Motor Coaches – connecting Washington, DC, via Annapolis (also on US-50) with Rehoboth Beach (in Delaware) and Salisbury and Ocean City (both in Maryland), all three on the Eastern Shore of Maryland and Delaware (on the Delmarva Peninsula) – until 1952, when the Carolina Coach Company (the Carolina Trailways) bought the Red Star concern.
In 1987 The Greyhound Corporation (the original Greyhound umbrella 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 Greyhound Lines, Inc., called also 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., called also TWI, also based in Dallas), which was by far the largest member company in the National Trailways trade 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.
[The contrived name Viad appears to be a curious respelling of the former name Dial – if one scrambles the letters D, I, and A, then turns the V upside down and regards it as the Greek letter lambda – Λ – that is, the Greek equivalent of the Roman or Latin letter L.] The website of the Viad Corporation (http://www.viad.com) in September 2008 makes no mention of its corporate history or its past relationship to Greyhound (that is, its origin as The Greyhound Corporation).
