| Here is left side of the centerfold in the January 1955 issue of "Trains" magazine, page 34. Photo Caption: "To celebrate the 100th birthday of Horseshoe Curve and the 75th anniversary of the incandescent lamp, Pennsylvania Railroad and Sylvania Electric Products set off 6000 photo-flash bulbs to take this photograph of Horseshoe Curve that makes it look like a child's wonderland of 4th of July sparklers. Enough bulbs to equal the output of 15 million 60-watt household lamps were mounted around the curve near Altoona, Pa. As the Trail Blazer (left foreground), en route to Chicago from New York, and two freights moved on the Curve on October 20, 1954, the push of a button illuminated 2 million square feet. The resulting flash made photographic history." Photo by Ben Claar of Hollidaysburg, PA. |
