Sadly it will take more than a couple weeks.  She has got a shattered RHS side rod among other problems.  She was not in good shape when I ran her back in 2015 and it probably played a part in this incident.  We suspect it was something like what happened to Blue Peter in the 90's.

There was a second such accident?

Yikes, a  broken rod...?  Yeah, I heard that perhaps her dry steam pipe imploded...?  Or that she got some water in her superheater?  Such things have happened...

And sadly, yes.  Some stored cars (and a GG1!) got away from a switching crew on the Cooperstown and Charlotte Valley Railroad a few days ago, and wound up across a paved-over road crossing and off the end of the tracks.  There was a video of the accident as it was actually occurring briefly posted on Youtube just last night, but it seems to have been taken down or hidden already.  A heavyweight Pullman was rolled into a ditch, but not sure about much else.

Yeah, absolutely destroyed.  

So far the only things I've heard about a drypipe implosion are speculations from the armchair people on this side of the ocean.  All my contacts over there tell me it's still under investigation.  I don't think they've got her dome off yet, still attending to the external damage.  I am of the opinion it was a priming issue similar to Blue Peter, because when the thing did stop and was filmed with steam still in it you do not see any vomiting of steam or water out from the cylinders and valves, and it is common knowledge that the seals on all the cylinder and valve heads are no good, so if it were a dry pipe problem there would have been water or at least steam pouring out of there even after it had come to rest.   Knowing the condition of the locomotive and having driven her and seen how she responded to closed regulator I'd also say a bad regulator seat played into it.   The driver should have known to bring the reverser just back of center though, and I guess he didn't.  Putting the reverser right in the middle on a Walschaerts valvegear locomotive can sometimes result in it continuing to run on "lead only" in the valve events, thanks to the combination lever.

Chrimatey, that's nuts

Very interesting analysis .  You do have a knack for such things!

Think she can be saved?
