267 is actually a pretty average load, especially on a weekday, considering that there are only a little over 340 total seats. On weekends I have seen many sell outs out of Raleigh. The peak is usually between Fredricksburg and Quantico.
While railfanning this this route by car several weeks ago, I drove through this location and thought that it was not a safe design. I would hope that VDOT takes a look at it now.
