It's Cinco de Mayo, and CSX's Rockwood to Johnstown local is switching their best customer, Pepsi Cola. The crew has dumped their train to the left and now grab a fresh string of corn syrup tank cars to shove into the transload facility. On this day, and most others, the Pepsi bottling plant will go through almost a tankcar and half of the sweet stuff. If you live in PA, WV, MD, OH or VA, chances are you'll be sampling the fruits of their labor.
