 The second half of the 20th century also saw significant changes to the rail line through the Pine Creek Gorge . Regular passenger service on the canyon line ended after the Second World War , and in 1960 the second set of train tracks was removed . Conrail abandoned the section of the railroad that passed through the gorge on September 21 , 1988 . The right @-@ of @-@ way eventually became the Pine Creek Rail Trail , which follows the path of the former Pine Creek Path . The first section of the rail trail opened in 1996 and included the 1 @-@ mile ( 1 @.@ 6 km ) section in the park : as of 2015 the Pine Creek Rail Trail is 62 miles ( 100 km ) long .
