Seein’ double A pair of Canadian National GE C44-9Ws sit side-by-side in Jasper, Alberta, on August 6, 2016. The two sisters are equipped with a CN-specified custom windshield, and are pretty much identical, with No. 2616 delivered in 2000 and No. 2699 built in 2004. The only differences I can spot are slightly different MU plug placement between the two, and the additional DPU light on No. 2699.
