OK, not really official, because I doubt ATSF actually did this, but I'm curious. We've gone back and forth on this on this site before. Generally, at our most precise, we've had the following Zebra Stripe Pin Stripe Warbonnet Yellowbonnet (F units, yellow & silver) Bluebonnet (F units, blue and silver Cub Scout (trainboard specific. refers to the 1972 yellow bonnet on blue scheme.) In the wider ATSF community, how is this described? Does Yellowbonnet refer to the Yellow over blue? What about the Superfleet? is it described as just being in Warbonnet. Personally, I'm not that picky. I'll use war bonnet to describe the '72 scheme and expect the reader to use context clues to understand what I mean. My attitude is that if that offends you.....well, there are pills for that. But I accept that perhaps more precision is desirable. The reason I ask is that I got chastised on the PNWR Yahoo group for describing one of their former ATSF GP39-2s as being in Warbonnet paint. The chastiser said no, that was bluebonnet (which I'd argue was incorrect no matter what) My response was to provide the list I provided up there as a reminder that sometimes being nitpicky can blow up in your face. But still I was curious. is there a ATSF Hysterical society official convention for this?
