The first railroads were point-to-point systems for hauling quarried material. South Carolina's Palmetto Brick Company was still such a railroad in 2008 - and 36" gauge with link and pin couplers, as well! Here we see Plymouth #2 bringing an 8-car train past spare engine #1 (a Plymouth 10-tonner built in 1939). This line has since ceased operation, with trucks taking over the duties.
