It appears Rail Switching Service is adding another GP9 to its fleet. This unit (which does not currently show up on their roster) was spotted being serviced at the BNSF engine facility in Denver.
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"!)
