Bruce,
Your expanation is very good. I can see why I was lucky to earn a
grade of C in college in technical writing when most of the class was
pulling A and B in that class.
Many people will argue that there is no problem using the chain drive
reduction method on the coaches, but people that have been working on
these for long time admit that it does stress some of the components
on the trans.
