Caption: This afternoon trackside started out on the CN where eastbounds were being told they were going in the hole for at least 5 westbounds out of Saskatoon. However I got distracted by this CP when I overheard an interesting conversation. It was centred around the second unit (NS 1057) needing to be repositioned "behind the first trailing unit". Obviously this brought about some confusion as the NS 1057 was the only trailing unit. "Do you mean behind the first robot" the engineer eventually asked. Around this time I heard them go over the detector "total axles 8-4-0", and it all started to make sense. They were going to reconfigure the power arrangement from 2x1x1 to 1x2x1 on a double empty crude oil train. The plan was for them to this at the siding at Winter while 466 waited between switches on the main. Needless to say I got my shot and went back over to CN where things were actually moving.
