What is generally not known to today's transportation fans, is that many of the private railroads were active in the marketing of intercity bus services, mainly during the 1930's and 1940's. Some railroads formed bus subsidiaries, and operated buses to replace certain lightly used trains, along with buses along the railroad routes to thwart off bus lines competing with their passenger trains. While some railroads acquired stock in existing bus companies, which would complement the passenger trains.
Meanwhile, more intercity bus companies were getting together, forming the Greyhound and Trailways systems. Eventually Greyhound consisted of a number of regional companies with varying degrees of ownership by the main Greyhound corporation. While Trailways consisted of many separate companies working together as "members" of the Trailways system.
And many of these railroad owned bus companies eventually became part of Greyhound or Trailways. Some Greyhound regional companies became jointly owned by a railroad and Greyhound, identified with a Greyhound name. Or some railroad bus companies became members of the Trailways system, adding "Trailways" to their operating names. A few bus companies remained independent.
But by the 1950's, the railroads generally gave up all interest in the bus operations, with the routes becoming entirely owned by Greyhound or Continental Trailways. And despite Greyhound's early objections to Amtrak subsidies, Greyhound now recognizes the value of added passengers connecting to and from Amtrak trains. Both Greyhound and Amtrak benefit by working together, competing against the automobile.
