"Baldwin had a habit of delivering locomotives in green paint, similar to the boiler jacket paint color. I have to wonder if the Rio Grande didn't just paint the engines black but left the jacket in close to the original green. Fun to speculate but all is, of course, lost to history."
Your posting is a perfect segue to a question to which I haven't seen an in-depth answer - relating to the use of green on the D&RGW boilers. Specifically:
1. At any time were green boilers a standard? If so, then it would seem that there is an AFE around somewhere on the subject.
2. If an AFE exists, did it apply to all classes of steamers, or just a specific group - like passenger engines? Or NG vs. SG?
3. And, if indeed green boilers were used, what was the time period?
The only photographic evidence I've seen is a short part of an Emery Gulash color film of a train on Monarch Pass double headed by a couple of K class engines. I raised this question some time back and I was told, supposedly by someone with solid knowlege, that these two engines were painted by the Salida shop specifically for the railfan event that Gulash photographed.
Can anyone add to this info?
