There is then a sequential crossover in each direction to go from Track 2 to 1 as FX has a set of universal crossovers in-line with the yard crossovers.
I put this together to show the difference between a Yard 10 move via Yard 21 (Green/Yellow) and a no-longer-possible Yard 8 move via the mainline (Red/Orange). The basically straddle either side of Sullivan Square.

Also if done at the same time (???) a new connection could run left to right from the Green track across to the Mystic Wharf Branch which is where the words "Hood Park Dr" is shown. This would be approximately where the original FX diamonds were.
