. . "Duffy's Cut is the name given to a stretch of railroad tracks about 30 miles west of Philadelphia, United States, originally built for the Philadelphia and Columbia Railroad in the summer and fall of 1832. The line later became part of the Pennsylvania Railroad's Main Line. Railroad contractor Philip Duffy hired 57 Irish immigrants to lay this line through the area's densely wooded hills and ravines."@en . . "Duffy's Cut"@en .
