This is correct. But if I understand properly, the same Keystone train carried a passenger NYP-PHL, it gets counted as an NER. If a passenger boards a regional in Charlottesville and gets off at WAS, it counts as the Roanoke service line. If he boards at Charlottesville bound for New York, it credits credited to the Roanoke service line. If he boards at Washington, however, he gets counted as an NER. That seems to be the only way the numbers make sense historically. Otherwise we would see dips in the NER every time a train gets extended into VA, which is not the case.
