Comments on: CN only rebuilt 10 of its GMD F7B freight B-units as part of their F7Au/F7Bu rebuild program in the mid-70′s, but they got their mileage out of the cabless units and seemed to use them wherever they could, whether it was in pure A-B-A Sets of F-units or mixed in with other models at random. Here on a less-than-ideal day, Reg was out to capture a rather unconventional lashup: CN GP40-2W’s 9640 and 9656 splice F7Bu’s 9198 and 9196, flying white extra flags on train #431 (with pulpwood racks up front) as they roll into Niagara Falls at Portage Road. The purists would scoff, but I suppose this qualifies as an “A-B-B-A” consist. The figures on the hill in the background are golfers enjoying some time on the course nearby.
