| RF&P had a cab signalling system that was not compatible with anything else, and off line power was not equipped with it, even major connection SCL. This is why you never see foreign power leading there. Train 171 is south at AF with an RF&P leader, added at Potomac Yard just to the north. Looks like the railroad was anticipating a quick turn on the power-RF&P got pretty good utilization, and it was not unusual to see the same power twice in a day-since they added a unit on the rear of the consist as well. The extra power will surely not be needed to roll the train's 96 cars over the RF&P's profile. Of note, three years from the CSX merger, the renumbering has taken hold in earnest. All three CSX units have been renumbered into the 6000's, with the 6531 already repainted. |
