Major development came to East Pennsboro Township in 1905 with the establishment of the Enola Railroad yards. The yards covered 300 acres of land and extended five miles in a north-south direction along the Susquehanna. During World War II, the rail yards consisted of 217 sets of track that handled 10,000 rail cars a day.
Another early industry in the Township near West Fairview was the Harrisburg Nail Works, erected in 1831. At its height, the company produced 6,300 tons of nails annually. West Fairview Park still includes some of the initial foundation of the old mill, which was dismantled in the early 1900s.
In additon to the approximately 20,000 people who have made East Pennsboro Township their home, thousands of residents of nearby communities know East Pennsboro as their place of employment. An estimated 12,000 people work in the Township’s corporate office complex area which is home to many major companies including EDS, Rite Aid Corporation, Highmark (formerly PA Blue Shield), Holy Spirit Hospital, and Gannett-Fleming Engineers
