Instead of attempting to pry up the track and shim it, which would be difficult since it's all ballasted, I took advantage of L-girder construction. I made a 0.045" thick styrene shim, loosened the two screws holding the cleat to the OSB sub-roadbed, put in the shim, and tighten it up. Misalignment gone.
Smart. Good thinking.
Your substation, as ever, is looking spectacular.
