Name	Type	Comments	Date

John Teeter	General	ex-MP 3232 to be exact. Off current UP roster; so anything else is just conjecture.	11/4/2014 7:34:59 PM

mikey cruz	General	no # boards, maybe on it's way to a new owner.	11/5/2014 1:05:48 PM

mikey cruz	General	all I could find was it was up for auction on july 31 at ADAMS auction and it had no prime mover at that time.	11/5/2014 1:23:26 PM

Fred Stuckmann	General	Thanks for your insight Mikey.	11/5/2014 6:18:54 PM

Robert Beichler	General	UP is selling all of their SD40s and most are going to other roads, maybe W&LE ? Nice series.	11/5/2014 7:47:09 PM

UP 8955 is all I could find to go on.
But the UP name is crossed out, any ideas? An old Mopac most likely.
