The Story

From 1850 to 1884 the Pennsylvania Coal Company operated a gravity railroad between lower Pittston and Hawley, moving anthracite across the rugged coal country of northeastern Pennsylvania. Near this point the line crossed the highway on an overhead trestle at what was designated Plane No. 7 โ€” one of the inclined planes that let gravity and stationary engines move loaded cars over the hills. It was part of a vast network built to carry coal out of the region.

Why it matters

Gravity railroads like this one were the ingenious backbone of the anthracite trade, engineering that fueled the industrial growth of 19th-century America.

The "Pioneer" marker

Scranton, PA

In the mid-19th century, northeastern Pennsylvania's anthracite fields ran on ingenious gravity railroads โ€” lines that let loaded coal cars coast downhill by their own weight, with stationary steam engines hauling the empties back up a chain of inclined planes. The Pennsylvania Coal Company's route carried anthracite between the mines around Pittston and the canal at Hawley for more than three decades. This surviving 'Pioneer' car, retired when the gravity line gave way to conventional steam locomotives, was handed over to the City of Scranton in 1909 as a relic of that vanished technology.

William W. Scranton (1917-2013)

Scranton, PA ยท est. 2016

William W. Scranton belonged to the family whose name the city bears, and he came of age as its anthracite economy was fading. A World War II pilot, he served in Congress and then as governor of Pennsylvania in the 1960s, pushing to modernize the state's industry, highways, schools, and welfare programs. His later roles as a United Nations ambassador and adviser to presidents made him a national figure across decades of public life.

First Electric Cars

Scranton, PA ยท est. 1948

On November 30, 1886, Scranton launched what is celebrated as the first street railway system in the United States built entirely for electric operation, running between the city center and the Green Ridge section. In an age when most urban transit still relied on horses, this was a bold leap into a new technology. The achievement earned Scranton its enduring nickname, the Electric City.

Lackawanna Iron

Scranton, PA ยท est. 1947

Long before Scranton was a city, iron was already being forged in the woods of Slocum Hollow as early as 1797. In 1840 the Scranton family and their partners launched the works that became the Lackawanna Iron Company, and in 1847 the furnaces here rolled iron rails for the Erie Railroad โ€” helping tie together the nation's booming rail network. The company added steelmaking in 1875, riding the Gilded Age industrial surge, before the operation finally closed in 1902.
