In some cases they do lower the track.  But this tunnel has a rock floor AND at 
the east end the tracks cross a bridge across the New River immediately past 
the end of the tunnel so they could not lower the tunnel floor. 

The next 3 tunnels west of the Cowan tunnel will get the floor lowered as well 
as shifting the tracks more towards of the center of the former double track 
tunnels.

Easier to excavate the bottom than the top.

See what Norfolk-Southern is doing to get double stacks through old

tunnels.  A short video on an interesting MOW operation with a big payoff.
