I worked for GL at OMD in 1971,72, and 73....
Omaha was at one time the headquarters for 'Overland Greyhound Lines'. It was a very large hub, with mainline and branchline routes extending in all directions. It also had a large garage a few blocks from the depot. The depot, at 18th and Farnam, was an interesting 'art moderne' style, in vogue at the time of it's building in the late 1940's. It had lane style loading undercover, as opposed to sawtooth style platforms. It had the offices and restrooms on a balcony, and also had a Post House lunch counter, and several retail shops.
When I was there, Greyhound ran six thru transcontinental schedules basically on I-80 from points East, (New York or Washington) Chicago, Davenport, Iowa City, Des Moines to North Platte, Cheyenne, Salt Lake City and points West (Portland, San Francisco, or Los Angeles. In the summer months, they added three additional trips mostly going express. Also trips direct from North Platte to Denver were added. There were also a local to Grand Island via Fremont and Columbus, a local to Norfolk via Fremont, several shuttle trips back and forth to Lincoln, three more trips to Chicago via US 30, thru Ames, Cedar Rapids, and Clinton. There were five daily trips south to Kansas City, some continuing beyond KC. There were also five trips north to Sioux City, some continuing north to Sioux Falls, with connections north to Fargo and Winnipeg. There were three trips northeast to Fairmont and Minneapolis.
Even with nine trips a day west in the summertime, some of them ran in two or three sections regularly.
Not to mention, Continental Trailways also had a similar (although smaller) operation there out of their 16th and Jackson depot....
It truly amazes me how they could go from all that to what is now......
Only Amtrak remains basically unchanged from those years at OMA to what they have today....
