Remarks: Close, but not close enough to keep from stopping the camera. Less than a minute after 564's helpers thundered out of sight (see 'Rattling Bones At Cassandra'), a westbound empty PP&L train rounded the curve behind a solid trio of SD60Is - 6739, 6729, and still-blue 6718, formerly Conrail 5611, 5596, and 5578, respectively. The 6718 was the third CR blue unit I saw this trip; one for each day.
