The reason I ask is because I was looking for an old train wreck, and did find what look like axles with wheels. But on measuring with Sonarview, they come out to about 9 feet long... that is twice the proper train gauge. BTW the depth is only between 5 and 10 feet... very shallow, if that makes a difference.
I had given up thinking I had found train wheel/axles, but then thought maybe it was the measuring tool which was incorrect, and these might still be train parts. What is everyone's thoughts/experience with this?
