A little background on #9's rear tender truck wheels:
A flat spot developed, I think in 2018 or early '19, and has been getting progressively worse. It was becoming unacceptable during February's events.
Wayne was visiting last week for a few days, and I conferred with Jason to see if this issue could be addressed while no events were scheduled for a few weeks and help was available. The plan was to jack up 9, remove the tank truck, turn the wheels, and reassemble. With some luck this could be done in the time that Wayne and I could be there and not impact other activities.
What we discovered on Thursday, when the truck was finally out after carefully jacking up 9, was that only one of the rear wheels had a bad flat spot, and the other wheel did not, but was starting to 'shell' in one spot.
However, there was a problem.
As Jason explained, these wheels are 'chilled cast iron' which basically means that the running surface of the wheel is chilled in the casting process and results in a surface layer that is nearly as hard as ceramic. This makes them pretty difficult to turn, and our attempts to turn them were fruitless. Jason and Brian later recalled that this was their experience a number of years ago, after we relearned that lesson.
Hence the hunt for a substitute wheelset which wasn't very successful. All the serviceable wheelsets we have had already been used for other rolling stock. Jason had some other thoughts but on closer inspection none of them would have worked or would have meant days of extra work. We were kind of stuck until Brian generously offered the wheelset off his box 51.
After consideration of alternatives, it was decided to go with the substitution, which if all went well would result in 9 being back together sooner rather than later.
So the pictures above were the result of that sequence of events, work, and discoveries. The flat spot was smoothed out as much as possible and should be OK under a boxcar which doesn't see that much use.
Wayne reported that the tender truck was successfully assembled and replaced under 9 on Sunday, with some work to be finished on the boxcar truck.
Thanks to everybody who pitched in to help, and especially to Brian for his generous offer, again.
