CSX North End Sub Improvements

I hear there's a recently installed universal crossover just north of the Petersburg station called Dunlop. Can anyone confirm?

Also, is the railroad connecting Bricks and Battle with a second main track?

There is a new double crossover at "Dunlop" called "Petersburg", also a new double crossover at FA, Meadow and South Weldon replacing single crossovers. There's a new double crossover at Armstrong, just north of Rocky Mount, about half way to Battle. Also new double crossover at Enfield. CSX is building a new intermodal facility between Armstrong and Battle with a lead going between those two points and new interlocking at "Bulluck", which is about 2 miles north of Battle. Not too mention that CSX has extended the double main line between South Collier and Carson. In short, there's been a major upgrade to infrastructure on the North End Sub over the last couple of years.

Are some of these improvements oones paid for by NC DOT to improve on times frome Selma north ?

I apologize for resurrecting an old thread but is the double tracking between Bricks and bullock still happening? TIA.
