IMHO the two K-37s are moving forward, Charlie -
The bushes above #497's stack look slightly wavy, like there's a bit of exhaust heat stirring the air, and the radius rods of both engines are below center – where they'd be positioned for moving forward, not being set out cold. Also, if that
is the loop track, it's unlikely a dead engine would be left there blocking it
. . .
