Re:engine #30

I was wondering if it were really necessary to jack up the locomotive and put it on trucks or whatever in the first place? According to the Baldwin tracing published in Bender's book, #30 had blind drivers so I was wondering if they could have just dropped the rods, maybe remove the leading and trailing trucks and tie up the spring rigging, loosened the brasses allowing the front and rear drivers a certain amount of "wobble" and gone *real* slow? It seems the biggest danger in that case would be dropping one of the center drivers between the rails, but if things were loose enough and they had someone walking along watching for such problems, they could avoid them.
At any rate, however they did it, it seems that it must have been a four star pain in the a** since they never brought #30 out again.
