Caption: The apparent drought of 9WLs leading outbound from CN's Mac Yard were briefly interrupted with a flash flood of 3 in the first week of April. BCOL 4641 and CN 2517 were paired together and were responsible for L516 on April 1st (if I recall correctly), then the duo led 435 on the 3rd ( http://www.railpictures.ca/?attachment_id=51759 ). Conveniently, the 3rd CWL leader took place when a number of railfans were out in Welland (myself included) finding CP 9014 in the yard. A good friend of mine who frequents Mac Yard notified multiple groups upon departure, giving plenty of time for us to roundabout onto the Halton Sub. Here it knocks down the bridge at Guelph Line on the last bit of mileage before merging with the Oakville Sub.
