The Agerton is protected by the Alabama Underwater Cultural Resources Act. You may dive there but may not touch, disturb, or remove artifacts from the wreck. It is currently under study by the University of West Florida.
I do not know of a locomotive in the river but it would have to be near a past or present railroad unless it was being ferried somewhere.
