Railway & Locomotive Historical Society Bulletin #13 (1927) has a report by railroad of this engine's performance.
Sister engines were the Virginia, Delaware, and New Castle. Pennsylvania was the first engine imported by the NC & F. New Castle appears to have been a copy made by E.A.G. Young.
Tube length was 6 ft 10 in (2.08 m) , except Virginia, which had 7-ft, 6-in (2.29 m) tubes. Boiler sheet measured 7/16 inches (11.1 mm) in thickness while the "heads" were 1/2-in thick.
According to Chief Engineer J. Knight, Virginia ran a circular trip of 33 miles for 17 months straight (July 1834-December 1836) and incurred a cost of only $50 for repairs. New tires cost $200.
