Jim,
     That really doesn't address the question.
     Let me rephrase the question. Given the N&W's penchant for making 
improvements was there not enough significant improvement in performance 
or reduction in needed maintenance to support a change over from the 
friction bearing rods? Also, was the cost a major factor being that it 
was getting late in the steam era?

Being that the last batch of Class A locomotives received the roller 
bearing rods, has there ever been a reason given that these same rods 
were not retrofitted to the other Class A's?
