Since San Bartolomé is a "switchback" with no counterpart, locomotives need to be run around the trains (and turned on the turntable) before proceeding. And since they've already taken the train apart, they also re-order the freight cars (for no apparent reason).
And yes, they're also turning locomotive 701, which has cabs at both ends.
From a hint of "Bee" (NKP 765), colorful "Bees" (KCS), "Bees" w/ "attitude", to "Bees" that "sting" your eyes, in their own way they have "Bee" on display! Equipment that "Buzzes" with Yellow & Black colors! ("Bees" can still "Bee" entering this "hive"!)
