When I was a child, in the late '50s and early '60s, as a regular summer vacation trip, my family would travel from Florida to Nebraska by train to visit relatives. One link of the trip was a daylight train from Chicago to Omaha. It must have been a crack train. I recall dome cars and a boat-tail observation lounge at the back. There was even a radio-telephone in the observation car that I always wanted to use but my parents said it was too expensive to use just for fun. As a young child I simply didn't appreciate the dining car lunch menu that no hot dogs or hamburgers but rather yucky stuff like fillet mignon, quail and brussels sprouts. At some point during the trip the train ran along a river, we'd go up to the dome car during that section and sit in an unoccupied seat for a while and enjoy the view.
Anyone have a guess as to which train it was? I don't know the answer.
