bigfreight,
The two engines (NHN and FGLK) were sitting at the east end of that long string of boxcars in Groveton yesterday morning, so, if you didn't see them going south, then they must still be there.
Also, of interest, I heard the light engine coming north yesterday morning around 0915 as I was working on the floodplain just south of Groveton. As I headed south on Route 3, I found the engine stopped just north of the crossing (2nd crossing south of Groveton), and there were two cars off the side of the road. It looked like the first car may have stopped for the train but the second car didn't and rearended the first. Just conjecture on my part. Hopefully no one was hurt badly, as this is a 50 MPH section of highway.
All the best,
Fritz
