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.

Famous quotes containing the words rolling, stock, reporting and/or marks:
“It is only when we are very happy that we can bear to gaze merrily upon the vast and limitless expanse of water, rolling on and on with such persistent, irritating monotony, to the accompaniment of our thoughts, whether grave or gay. When they are gay, the waves echo their gaiety; but when they are sad, then every breaker, as it rolls, seems to bring additional sadness, and to speak to us of hopelessness and of the pettiness of all our joys.”
—Emmuska, Baroness Orczy (1865–1947)
“I have, thanks to my travels, added to my stock all the superstitions of other countries. I know them all now, and in any critical moment of my life, they all rise up in armed legions for or against me.”
—Sarah Bernhardt (1844–1923)
“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)
“Roll on, thou deep and dark blue Ocean,—roll!
Ten thousand fleets sweep over thee in vain;
Man marks the earth with ruin,—his control
Stops with the shore;”
—George Gordon Noel Byron (1788–1824)
