You may want to leave a couple of holes in that level so that you can get a hand in from below. The section representing the sea can be really thin the section further back where the tracks are being a bit thicker. If you used a sheet of 3mm perspex for the sea, covered with a roll of the translucent "sea texture" plastic, it would be opaque enough not to see the trains below, until you deliberately light them up with a few LEDs so you can see where they are.
All good stuff!
A pear-shaped hole in the baseboard inside the return- loop curve could save some scenery removal, but this should still be a possibility.
I like the idea of backlighting the sea so that the storage lines become visible enough just when required.
I hadn't thought of that, but it's a definite alternate to arranging track occupancy circuits. 3mm Perspex should be adequately rigid, but any number of vertical pillars (matchsticks) can be added if required to ensure strength and stability, everything in the region being painted dark blue
(Or indeed lighter and more yellow towards shore.)
I'd attach a few strategic strong items to the sea/sea wall to act as convenient "lift points".
