The tracks had to be aligned when they were one track, and I then screwed them down near the bridge separation, When they were cut, they were aligned by default. On the other end, the hinges keep that part in line, they were laid and cut the same way.
You will notice the .05 thick spacers on the left side of the bridge. The Homasote on the freight yard is a true 1/2" thick and the Baltic Birch multi-ply is 11mm. thick. That gave me about a .05" difference in height, I took the cheap way out when I discovered that issue.
The only thing that remains is adding the contacts on the bridge to bring power to the freight yard. I picked up these spring loaded test contacts to mount on the freight yard side, they'll project about .1" above the mating surface and contact flat plates on the underside of the moving bridge to carry power to the freight yard. That way I don't need any power coming across the floor to power the freight yard.
