Pittsburg and Shawmut Railroad

The Pittsburg and Shawmut Railroad is often confused with the similarly named Pittsburg, Shawmut and Northern Railroad from which the P&S had its origins. Further adding to the confusion is the fact that both were nicknamed the Shawmut Line, both operated in roughly the same geographic area, and both used similar diamond logos during their history. In fact the two were separate and unrelated companies after their 1916 split.^[3]

The P&S operated on a single-track main line, with approximately 88 miles (140 km) of standard gauge track extending from Brockway, Pennsylvania to Freeport, Pennsylvania.^[4] The railroad operated using timetable and train orders without block systems until at least 1950.^[4] The main shops were located in Brookville, Pennsylvania.^[5]

Recent history

By 1986, the Pittsburg & Shawmut had interchanges with Conrail at Brookville and Freeport, and with the Chessie System at Dellwood and West Mongrove.^[6]

The company acquired a ten-mile (16 km) section of Conrail track running from Sligo to Lawsonham in 1989 and reorganized it as the Red Bank Railroad^{[citation needed]}. On December 31, 1991, the company purchased about 110 miles (180 km) of the Low Grade Secondary track from Lawsonham to Driftwood, Pennsylvania from Conrail and organized it as the Mountain Laurel Railroad.^{[citation needed]}

The Arthur T. Walker Estate Corporation had direct control of the company until 1996, when the railroad was acquired by the Genesee & Wyoming.^[6][8] The Genesee & Wyoming operated the Pittsburg & Shawmut Railroad under its own banner until January 1, 2004, when it was absorbed into the Buffalo and Pittsburgh Railroad, another G&W company. Simultaneously, a new company with the same name was created to purchase the property, which is now operated by the BPRR.^[2] (The P&S also acquired the residual common carrier obligation on the lines.) Today, most of the railroad is gone. The B&P ran the last train between Brookville, PA and Reesedale, PA in January 2000, and removed the tracks between 2005 and 2006. The main line between Brookville and Brockway was removed in 2003.

The Pittsburg & Shawmut operated with steam power until the entire steam roster was scrapped in favor of dieselization in late 1953.^[9][10] After 1953, motive power consisted of a fleet of EMD SW9 switcher locomotives and, later, EMD GP7s.

In the 1970s, the Pittsburg & Shawmut modified several aspects of the fleet to celebrate the United States Bicentennial: the warm yellow and red color scheme was replaced by red, white, and blue to resemble the nation's flag; locomotives were renumbered in honor of significant years in American history; and the locomotives were nicknamed after American historical figures and arms manufacturers.^[9]
