Re: 484 and 488

For what it's worth, I talked with Mark Yates, Bob Wright and Ed Beard.
484 will be back in the shop as soon as an engine can be spared to do the switching. 484 has the jacket stripped for an ultra-sound test, needs running gear work (all the wheels are off).
Guess 6-8 weeks if nothing else breaks, or next fall more likely.
488 needs new sheets, flues, running gear work, etc. Best guess is next winter.
Having 4 engines on the road is taxing, considering that all need to be serviced nightly and all need a boiler wash and flues blown every week or so. Then if anything serious breaks, the shop facilities and crew have to deal with that. So heavy mainteneance during the operating season is bound to go very slowly.
