OK, I guess it's time to weigh in.
The maintenance problems with #3 do not preclude it's use, but continued operation will cause increase wear on the cylinders and crossheads. This is normal for a steam locomotive of course, but those on the #3 are getting worn to the point where damage will occure before too much longer. Remember that we have put more miles on it than any other owner in it's 94 year history. I cannot say how much longer it can go however, it could very well last another season.
Getting a steady supply of wood could be a problem. There are no mills still operating in the area and loggers are nearly extinct. The last time we tried paying someone to supply wood the cost was about as much as oil and they had a hard time keeping up. Some of what they furnished was punky or sopping wet or both. As mentioned, the best way is to get log truck loads, but I don't know if that is possible now.
Having said all that, I remember when the engine crew had to split and load wood between runs. I also remember when we had less than $900 in the treasury to operate on for the season. The point is that we made it work, and I fully expect we will make it again. Granted the operation is much larger and more comlpicated than it was then, but we have much more experience now as well.
By the way, Laura and I are both doing well and hope to be back there soon. It will be a while before I am splitting wood however.
