   A CTC interlocking location is  referred to as a Control Point (CP). And is under direct control of the dispatcher. The most restrictive indication from a controlled signal is "Stop", since proceeding past the signal may mean entering directly into another train's route.

Penn Central identified Control Points by number (perhaps the CP # was derived from the mile post), 
but following Southern practice, NS names control  points.  By recollection, east end of double track
from Roanoke is now named MONTVALE.  It's certainly more identifiable than CP 239. Harry Bundy
