Caption: It's 07:30 at Mac Yard on September 1, 2015, and while waiting for the Engineering guys to arrive for a day of training on their the new Knox Kershaw KYC550 Yard Cleaner http://www.railpictures.ca/?attachment_id=20733, I was able to walk over from the Work Equipment shop to Green Tower/West Control and snap CN 7255 basking in the warm morning sun while the crew was in the tower picking up instructions on the next cut of cars to be shuffled. CN 7255 is ex-CN 4217 which can be seen in this July 1988 Seth B. photo http://www.railpictures.ca/?attachment_id=48491 My thanks to Seth B. for his time, effort, and handy work in cleaning up, straightening, and otherwise correcting my photo of CN 7255 to make it presentable.
