CP 7023, representing the Canadian Air Force, leads loaded crude oil train, CPKC 576, into the west end of Humboldt Yard.
The Air Force unit (CP 7023) leads ethanol train CP 650 past a set of signals on CP's Vaudreuil Sub, with heritage unit CP 7013 bringing up the rear. This was a surprising lashup, as this train had GE units into Toronto, where power was swapped (not a particularly common occurrence for this train).
CP's Air Force and Navy tribute units team up to lead CP 286 east past Tower B17 in Bensenville, IL.
Canadian Pacific's Royal Canadian Air Force commemorative schemed SD70ACU locomotive leads an eastbound CSX train near Boughtonville Ohio.

NGC 7023
The “iris nebula” is a bright reflection nebula in the constellation Cepheus (the King). Best seen in the Fall and Winter months, northern hemisphere. In astronomy, reflection nebulae are clouds of interstellar dust which might reflect the light of a nearby star or stars. Dust in space reflects blue light more efficiently than red which is why almost all reflection nebulae are blue. A similar phenomenon is the reason for blue skies! The designation NGC 7023 refers to the central star cluster. The Iris is “only” 1300 light years distant and about 6 light years across.
