From the Rocky Mount Telegram:
Ernesto cut a path through Eastern North Carolina on Friday, dumping up to 6.5 inches of rain on parts of Nash and Edgecombe counties. A few dozen low-lying streets and roadways were flooded, and about as many trees were felled during the peak of the storm.
Web sites for the National Weather Service and the U.S. Geological Survey indicated that the Twin Counties received up to 6.5 inches of rain, and wind gusts were reported up to 43 mph.
Note: Nash and Edgecombe counties, the twin counties, include the city of Rocky Mount; through which runs the CSX line in question.
Or perhaps these quotes from the Times Dispatch in Viginia:
Lights should be shining tonight for the vast majority of the 605,000 Dominion Virginia Power customers who lost power during tropical depression Ernesto, the company says.
The storm, which had a stronger wallop than forecast, caused moderate damage across most of Dominion's electrical system in central and eastern Virginia, the company said, and it also produced pockets of more severe damage.
Finally there is the CSX news bulletin posted here, which mentions that they shut down the line. It also talks about downed trees that they had to remove, as well as power failures to deal with.
