Railroad Construction & Service The U.S. has roughly 150,000 miles of railroad track in the U.S. While passenger service plays a limited role, freight shipment is a major contributor to the movement of goods and services. Keeping the tracks in operational, working order is paramount to the success of the industry, and the people behind that work require specialized service truck bodies and equipment. From new track construction to track additions and track maintenance, railroad employees utilize a variety of Summit Truck Bodies products to keep the industry growing every year. This includes the medium- and heavy-duty mechanic service truck, canopy body, flat bed body with knuckle boom cranes, fuel and lube truck, lube trailer, lube skid and specialized rail service equipment designed to drive on tracks.
