Two Locomotives Choo-Choo’d Under The Sea

A magnometer used by Paul Helpler, who was mapping the ocean floor near New Jersey in 1985, discovered two steam locomotives from the 1850s, 27,5 meters (90 ft) underwater. But there was no record of them being built and no way of knowing how they got there. Wowzers!
