@AndrewE -- we are, basically, in accord. Dotsero and Orestod are the junctions at ends of a 40-mile-odd cut-off line inaugurated in 1934, after the D & RG's having acquired the D & SL -- which never achieved its proclaimed objective "under its own steam" -- just ended up petering out in the middle of nowhere (with all due respect to the town of Craig) a couple of hundred miles west of Denver. The new cut-off shortened immensely, the east-west route between Denver and Salt Lake City.
Name Dotsero: one interpretation -- as per yourself -- is the surveyor's "Dot Zero". Another is, the spot's reputedly having long been called "Dotsero" in the language of the area's Native Americans, the Ute tribe -- meaning, "something new". Centuries ago, there was a volcanic eruption near the spot, after a very long period of volcanic quiescence -- truly, for the Utes, "something new". Orestod, for sure, "Dotsero" backwards -- as you say, a bit of wordplay re the new junctions at beginning and end of the cut-off.
Per the detailed railroad atlas: Bond is not actually on the "new" cut-off line, but a little way along the old line off from the new junction -- kind-of resembling, though the other way around: Settle station, and Settle junction between the "Little North-Western" and the S & C. I'd read your "O B & D" 's "B", as signifying the station of Burns, actually between Orestod and Dotsero.
Anyway, you have it -- your floor. Go stick it to those Limeys with the question from hell
