Remarks: Although trailing a GE C40-8W, SD50 #8522 is only one of 83 active units on the CSX roster. With 8 units as of now de-rated to SD50-S, and #8512 off the roster for unknown reasons, seeing an SD50 is becoming much more of an exciting experience in my opnion. One of the 83 remaining SD50 units is seen here on this CSX freight in New Jersey. This is on CSX's Trenton Line.
