Henry, What you say is true, but that is not the point of the few prededing posts.  The point of those posts is slack run-out causing a pressure drop in the trainline, which then dynamites the brakes.  Look at the reference in blue the fifth post above this one. Actually, in looking at it again, I see that they don't specify run-out or run-in.  They just refer to slack action causing brake pipe pressure to drop.  I am mystified.  Can you explain how slack action can change the pressure in the trainline?
