We have worked on a diversity of railroad projects throughout the country for nearly two decades. Our success has made us the ‘go to’ electrical and fiber-optics contractor for some of the largest railroads in the nation. Potelco rebuilt the electrical system in the Steven’s Pass Railroad tunnel, the longest rail tunnel in North America. In addition, we’ve completed crossing upgrades, pole change-out programs, high voltage cable installations, fiber-optics installations and entire rail yard system rebuilds.
