Of the 6 major North American Railways CP was
the last in performance share price was $ 46.00 today it is 128.00 ... thank you
Bill Ackman.

Another one who has no idea at what cost the shares hit 128.00. 
How does one get to that super share price? By getting to a low operating ratio; that fools all those who have not the slightest idea how it was achieved, all they see is $$$$$. 
No inkling about deferred maintenance and that the piper will need to be paid. No inkling what maximum utilization of motive power does and on and on and on. In short, no inkling!
Back in 2012 when Ackman and Harrison  arrived I knew what would result, seen it at CN.
My prediction when the changes started: "Just wait for the first tough winter "the Hunter" won't look half as smart". Sure enough 2014 proved the point.
Perhaps instead of reading the stock reports you could read the Transportation Safety Board reports on CPR and get the real picture.
