Just noticed they're moving the heavy cranes and gantry's over the discharge section of the dam. They have put rail cars loaded with coal on vulnerable sections of dams bridges and levy's on the Mississippi to try to hold them down and change cavitation harmonics.
CCP/PLA might be trying to do the same thing. It will be a tell if all of the cranes end up there. They're on tracks, so they might bring in some ore cars too. Bears watching.
