Inscription.  ”So far back as 1827, the Company constructed down-grades on which loaded cars were run down to the Lehigh River by their own gravity.”
—“Special Correspondent, New York Times, December 14, 1872, p 3.”

Geography posed a problem. While gravity efficiently pulled coal cars down from the mountain mines, the final decline to the river proved too steep for conventional railroad cars.

Josiah White, co-founder of the Lehigh Coal and Navigation Company, found the answer in 1827. He designed a series of inclined planes, including a 700 foot plane near here.

As with all White’s inventions, simplicity dominated design. A gravity operated turntable directed cars to one of the planes. Above, a counterbalance system took over with the descending loaded car pulling the empty car back up the plane. At the bottom, the coal was dumped into [unreadable] canal barges or open railroad cars.

. The railway used gravity and two inclines. A powered double-incline led up to the top of two separate summits along Pisgah Ridge on the return leg and each summit had "a new down track" returning the cars several miles farther west in each case. This saw-tooth elevation profile gave the new return track a swooping characteristic ride later deliberately designed into roller coasters.

2. How the Switchback Railroad Inspired the Invention of the Roller Coaster. The Switchback Gravity Railroad, built in 1827, was only the second railroad built in America. It ran nine miles, hauling coal from Summit Hill down to the town of Mauch Chunk and the Lehigh Canal in east central Pennsylvania. During non-peak hours, the railroad offered rides along the route for the public, in specially outfitted cars. Following the line's dramatic descents and loops, these cars could attain speeds of up to 50 miles per hour. One patron described it as a "hair-raising trolley ride." This wild ride—in which carloads of passengers plunged at high speeds from steep peaks—served as the model for the first roller coaster, introduced on Coney Island in 1884.
