Several recent messages clearly use the word MANDATORY and that is what
prompted my tirade here. The writers of those messages were very clear with
their intent.
>I think they say it's usually better to do it that way.
It all depends on who "they" is. Some folks are more knowledgeable than
others. Read back over the messages on this general subject on this list and
you will see what I mean.

The point I am making is that isolating the frogs is NOT MANDATORY. This is
the ONLY point I am making. I am making no attempt to state that one approach
is better or worse than the others. Makes no difference what the throwbar is
made from, my point is still the same -- isolating frogs is NOT MANDATORY.

You just described the Mighty NYC which has 75 turnouts and works just fine.
No need to change anything. Not one single isolated frog. I would do it again
if the opportunity arises.
