Thank you Dave, appreciated. I look forward to learning what you find out. No rush for an answer, just curiosity.
Since posting this earlier I have read a reply to a similar post I made on the Trains Magazine Forum. A reply there says that there are a good many NS locos stored on the tracks to the west and what I saw might be a movement of these locos to another set of tracks and/or them possibility that one or more of the locos might have been required and were removed from the consist.
Another reply mentions issues involving CSX and consequently NS could be gearing up to gain advantage.
