I have a picture in Union Pacific's 2010 calendar-the June photo shown here of a UP train passing Union Station in Little Rock in July 2008. If you want a copy, you can order one from the Arkansas Railroad Club, which is selling them as a fund raiser. Cost will be $13 each, which includes postage and handling.
