Re: 4-4-0&2-6-0 (s.g.) Baja Calif-Me

Hmm. All right, let's be optimistic and say that on the first dig we hit our quarry (as opposed to, say, someone's discarded Studebaker). How do we get the engine(s) out of the pit(s)? I remember having a terrible time getting three derailed coaches back on the track, and they were 3' gauge. A big crane springs to mind, but how do we get a crane that can lift over a hundred tons out in the middle of nowhere, and if it's loose, sandy soil, how do we stabilize things? (I'm not trying to be a downer; mostly, I'm playing devil's advocate)
Now, what sort of damage was probably done to the engines in the accidents themselves? They both went into cold mud and water under steam (I assume), with water in the boilers and maybe the cylinders. In the seventy-odd years they've been underground, there haven't been any major civil engineering projects in the area (that I know of) and I don't know how deep the engines are or how high the water table is in that area.
The next stages are going to be very interesting . . .
