Much as I was prepared to dislike the Oregon Health Sciences University tram on principle (I still think they should have built a tunnel), I have to admit that the thing looks cute when the pods are gliding silently above Interstate 5. I think of the cabins as "pods" rather than "cars" because they look like pods from below, fat white peas that fade into the fog and mist of winter. Calling them pods led me to think of better names for the two cars than my first suggestion, which was to call one "$30,000,000" and the other one "Each."
For "Pod" in children's literature brings to mind Mary Norton's series about the Borrowers, a group of hominids a few inches tall who live in nooks and crannies of houses and "borrow" from the humans around them the things they need to survive and live comfortably. Pod is the name of the father of the family that is at the center of the stories.
One of Miss Norton's books describes a business war between two hobbyists named Pott and Platter who operate model railroads in their yards a few miles from each other: as they each upgrade their model railroads, when one's fortunes go up, the other's go down. Platter charges high admission fees to see his railroad; Pott is content if the adults who visit put a penny in the tin. Consider "Pott" and "Platter" as names for the tram pods: when one goes up, the other goes down. The capper to this is the name of the book that features Pott and Platter: it's called The Borrowers Aloft. Could anything be more suited?
