Ok, looks like the sub was transported from water to shelter via railway cut then the whole works was destroyed in place, leaving only the carcass of the sub [or subs, looks like 2, other one likely shipped to Pearl for evaluation].
This guy was there a whole summer specifically studying war relics, he must have 100's if not 1,000's of photos, maybe planning a book.
Then again, hard to gauge how extensive the relics are there.
