I don't understand why you have made the reversing sections where you have, unless you're trying to equalize the loads on the power districts, and the Autoreverser is your fourth district. Most of the mainline is reversed, for no reason I can see.
I'd autoreverse the track beginning with Westfield, gapping both rails of both tracks coming into Westfield from the left, gapping the main line before the first turnout to reduce the number of double gaps. Or, if the turnouts are power routing like my Shinoharas, then gaps will be needed on the point rails between those two turnouts, so I'd gap both rails of all three tracks, just below the left end of the Westfield spur track.
I'd continue the reversing section unbroken through E, F, and C to Dubois, making certain the track from the turnout below C to the double gap at Dubois is at least as long as your longest train. That's all. Not including Dubois or Wellsville.
Every place the yard connects to this autoreverse section needs both rails gapped, of course. There is one place between B and C, where the yard track connects to the mainline, one near Galeton, where the opposite leg of the turnout should be double gapped, one where the green yard track connects again below B and above Westfield, and both tracks near the arrow at F.
I'll try to send printouts with my suggested reversing sections highlighted and pencil marks where I'd gap both rails. Look them over, and see if they leave or create any problems.
