Is this to say that you disagree with the thrust of my last post? Perhaps
I'm misreading you. You aren't seriously suggesting that the person on the
train is any different are you? What could it posssibly mean to "feel
yourself being accelerated" that is any different from how you "feel" when
you are standing on the ground? Do you really mean to imply that there is
some way for the person on the train to distinguish between the "forces
from deceleration" (as you called them in your first post) and what we
generally refer to as a "gravitational force"?

John,
What is the train rider to make of the coincidence that these
gravitational fields always appear when (and only when) the engineer
applies the brakes or the accelerator?
