Here's an April 2004 photo of GP9 1600 at North Bay Yard waiting to begin the afternoon's Yard Detail. This is one of two of ONR's GP9's (the other being 1604) to recieve the "chopped nose" facelift for improved visibility by the Crew.  Other recent upgrades include the addition of both front and rear ditch lights along with the installation of spark arresters to the exhaust stacks.
