 The second half of the 20th century saw great changes in the rail line through the park. 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 passing 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 2008 the Pine Creek Rail Trail is 63.5 miles (102.2 km) long.
