Rolling Stock Reporting Marks
Every piece of railroad rolling stock operating in North American interchange service is required to carry a standardized set of reporting marks. The marks are made up of a two- to four-letter code identifying the owner of the equipment accompanied by an identification number and statistics on the equipment's capacity and tare (unloaded) weight. Marks whose codes end in X (such as TTGX) are used on equipment owned by entities that are not common carrier railroads themselves. Marks whose codes end in U are used on containers that are carried in intermodal transport, and marks whose codes end in Z are used on trailers that are carried in intermodal transport, per ISO standard 6346). Most freight cars carry automatic equipment identification RFID transponders.
Typically, railroads operating in the United States reserve one- to four-digit identification numbers for powered equipment such as diesel locomotives and six-digit identification numbers for unpowered equipment. There is no hard and fast rule for how equipment is numbered; each railroad maintains its own numbering policy for its equipment.

“As artists they’re rot, but as providers they’re oil wells; they gush. Norris said she never wrote a story unless it was fun to do. I understand Ferber whistles at her typewriter. And there was that poor sucker Flaubert rolling around on his floor for three days looking for the right word.”

“Death and life were not
Till man made up the whole,
Made lock, stock and barrel
Out of his bitter soul,”

“I have been reporting club meetings for four years and I am tired of hearing reviews of the books I was brought up on. I am tired of amateur performances at occasions announced to be for purposes either of enjoyment or improvement. I am tired of suffering under the pretense of acquiring culture. I am tired of hearing the word “culture” used so wantonly. I am tired of essays that let no guilty author escape quotation.”
—Josephine Woodward, U.S. author. As quoted in Everyone Was Brave, ch. 3, by William L. O’Neill (1969)
“The unread story is not a story; it is little black marks on wood pulp. The reader, reading it, makes it live: a live thing, a story.”
—Ursula K. Le Guin (b. 1929)
