Caption: On an eventful trip around Maple on Canada Day in 2022, we stopped by the pullback tracks at CN's MacMillan Yard on the way home before dinner. The usual hump sets have an SD40Q, slug, and another SD40-variant trailing. This set with 6003 and 250 had a nice surprise today: GTW SD40-3 5954! Built as a standard SD40 by GMD in May of 1971 as CN 5185, it was part of a group of retired units rebuilt by Alstom in 1998 to lease to KCS, before being leased and later purchased back by CN (and bestowed GTW 5900-series numbers).

Unlike the CN 6000-series SD40Q units that had their cabs, noses and other details modified, the rebuilt Alstom SD40-3 units still retain most of their "SD40 look" and CN/Canadian spotting features (handrails, steps, split CN air tanks, nose headlight/cab bell, inertial intake snowshields behind the cab), so this is the closest one will get to a pure original Canadian SD40 on CN today. The large round numbers were no doubt from IC's Homewood Shops inventory. These units also used to have large "CN" logos on the long hood, but when the fleet was stored/retired around 2011 they were buffed off (most units were later reactivated and put back to work).
