And the BBC has picked up the story. You can find the story on-line at http://news.bbc.co.uk/2/hi/uk_news/scotland/glasgow_and_west/8282778.stm

These "arms" also show up on the flag of the city (about which - that is, the flag - more information can be found on the Flags of the World website at http://www.fotw.net/flags/us-kstpk.html).
The logo of the UPRR is basically a shield of the arms of the United States (well, they do reverse the tinctures of the paly field; in the U.S. arms they are paly of thirteen argent and gules, while on the UP logo they are paly of thirteen gules and argent), with the addition of the words "UNION PACIFIC" one above the other in white letters on the blue chief. Here’s a color version, photographed from the side of a UPRR boxcar.
The bottom line? It’s not "real" heraldry, but it comes close.
One of the buildings in downtown Omaha had some blank shields between pairs of neo-Gothic arches spaced regularly about the exterior. ("Why blank shields?", I find myself asking. But in much of the American architecture I’ve looked at, I have found far more blank shields and cartouches and oval shields than I have found with coats of arms or even faux coats of arms carved onto them. As a herald, I find this to be a shame, but I suppose it’s easier, and cheaper, to put up a blank shield than to research an appropriate coat of arms to place on it. But I digress.)
On that same building was an actual, honest-to-goodness crest! No torse, but identifiable as a crest nonetheless. It took just a few minutes of research in Fairbairn’s Crests of the Families of Great Britain and Ireland to learn that it was the crest of Stanley (Northampton) which is blazoned as: An eagle, azure preying on a child proper, swaddled in a basket gules. There are several families which bear a crest of an eagle preying upon an infant, but the Northampton family of Stanley appears to be the only one where the child is not only swaddled but is laid in a basket.
Built in 1888, probably its most noticeable feature is the statue of the eagle, snake in its claws, with its eaglets in the nest immediately below the rock on which it perches.
But, of course, as a herald the eagle is not what drew my eye first. Shield shapes. That’s what catches my eye. And there was, in two places on the facade, one on either side of the main entrance, these really great shields. No real heraldry, alas, and it took me a little research to figure out what the monogrammatic letters on the shield stood for. While it may be called The Omaha Building now, it was originally built for the New York Life Insurance Company. And if you take just a moment to carefully study the shield, sure enough, you can pretty easily make out N-Y-L-I-C. (There's also that lion's face above and to the left of the "arms", one of a row of such lion's heads along the length of the facade.)
Finally, there was this really great double rose, placed directly over the main entrance to the building. (I won’t call it a Tudor rose, since it has no tinctures, and Tudor roses are always a combination in one way or another of red and white, or more specifically the red rose of Lancaster and the white rose of York.) But what a beautiful piece of carving of a classic heraldic charge.
The most "complete," if you will, was what I call "an achievement of fake arms", a sign hanging over Ashley’s gift shop in the Old Market in Omaha. Parts of it are pretty classic heraldry; other parts are maybe not so much. Yet in a number of ways it comes so close. Good contrast: vert on or on the shield. A castle proper for a crest, atop a barely noticeable torse argent and gules. Two stags proper as supporters, but gorged of yellow bow ties, and standing atop a pair of logs which are then superimposed on one of the old Victorian "gas bracket"-style compartments. And, of course, the "motto" is no such thing, but merely a description of the goods carried by the store.

While this is an answer that may apply to some folks who want to use heraldry, I think that for most people, it’s a little too simplistic. That is, I think many people’s interest in heraldry is far more complex, and interesting, than just a desire to set themselves apart from the riff-raff.
