Motivated somewhat by the comment by &quot;sdfourty&quot; a week or so back, &quot;love those zebra stripes&quot; got me digging out this image of 6 of &#039;em climbing the grade past mile 4, Dundas. In the background are remnants of the old Canada Crushed Stone plant. Powering the train westward are CN 2540, 5144, 5046, 9562, 5079 and 9418. Leader M-420(W)part of series 2500-2579 later renumbered to 3500-3579 and all off CN roster by 1998. This engine went to Carlton Trail Rwy and became their 3554.  Height of trees these days has removed this vantage point from the list of decent locations to shoot from.
