140 years of rail

Tad Calcara of Salt Lake City and his 3-year-old daughter, Sabrina, watch the steam engine Jupiter make its way along the tracks Sunday at the Golden Spike Historical Site during the re-enactment of the driving of the last, "golden" spike, linking the Union Pacific and Central Pacific railroads at Promontory Summit in northern Utah on May 10, 1869. People wait in line to board one of the steam engines used during the annual re-enactment. This year marks the 140th anniversary of the completion of the nation's first transcontinental railroad.
