Recovering a large steam locomotive from a freshwater lake

How could a large steam locomotive be raised from an inland lake, with the stated depth corrected from 8,000 to 800 ft?

The panel discusses surveying its condition and lifting it gently using straps and bags or a supporting cradle. The correction to 800 ft changes the access discussion, and frame corrosion determines how the load should be supported.

The question initially gives a depth of 8,000 ft, then corrects it to 800 ft. At the original depth, the discussion assumes submersibles would do the work because ordinary diving access would be unavailable. The proposed lift uses straps and bags to raise the locomotive gently, with a supporting net or cradle and a crane considered as it approaches a more manageable depth. A recently lost locomotive with a sound frame presents a different problem from a heavily corroded artifact. After the depth correction, the panel discusses a diver-led survey to decide how to support the load. One view favors bags for metal artifacts, while another favors a cradle where a degraded frame requires careful control of loading and orientation.
