/ 1705 Pittsburgh Express (Scranton-Pittsburgh) Additionally, the DL&W ran commuter operations from northern New Jersey suburbs to Hoboken on the Boonton, Gladstone, Montclair and Morristown Lines. Early publicity for the passenger service featured a young woman, "Phoebe Snow", who always wore white and kept her clothing clean while riding the "Road of Anthracite", powered by clean-burning coal. Decline (1940–1960) The most profitable commodity shipped by the railroad was anthracite coal. In 1890 and during 1920–1940, the DL&W shipped upwards of 14% of the state of Pennsylvania's anthracite production. Other profitable freight included dairy products, cattle, lumber, cement, steel and grain. The Pocono Mountains region was one of the most popular vacation destinations in the country—especially among New Yorkers—and several large hotels sat along the line in Northeastern Pennsylvania, generating a large passenger traffic for the Lackawanna. All of this helped justify the railroad's expansion of its double-track mainline to three and in a few places four tracks. Changes in the region's economy undercut the railroad, however. The post-World War II boom enjoyed by many U.S. cities bypassed Scranton, Wilkes-Barre and the rest of Lackawanna and Luzerne counties. Fuel oil and natural gas quickly became the preferred energy sources. Silk and other textile industries shrank as jobs moved to the southern U.S. or overseas. The advent of mechanical refrigeration squeezed the business from ice ponds on top of the Poconos. Even the dairy industry changed. The Lackawanna had long enjoyed revenues from milk shipments; many stations had a creamery next to the tracks. Perhaps the most catastrophic blows to the Lackawanna, however, were dealt by Mother Nature. In August, 1955, flooding from Hurricane Diane devastated the Pocono Mountains region, killing 80 people. The floods cut the Lackawanna Railroad in 88 places, destroying of track, stranding several trains (with a number of passengers aboard) and shutting down the railroad for nearly a month (with temporary speed restrictions prevailing on the damaged sections of railroad for months), causing a total of $8.1 million in damages (equal to $ today) and lost revenue. One section, the Old River line (former Warren Railroad), was damaged beyond repair and had to be abandoned altogether. Until the mainline in Pennsylvania reopened, all trains were canceled or rerouted over other railroads. The Lackawanna would never fully recover. In January, 1959, the final nail was driven in the Lackawanna's coffin by the Knox Mine Disaster, which flooded the mines
