Except,,,,,,,,,,,N&W "boilers", including the firebox, were designed/modified/improved to burn West Virginia Pocahontas Range, VERY high BTU, coal. I wonder how well they would have worked with the Santa Fe Bunker C oil fuel?
A good question for which I don't have an answer for. It's an interesting footnote none the less for the Santa Fe given they had virtually sworn off articulated locomotives.
Still, apparently the Santa Fe was sufficiently impressed with how the Y3's steamed on whatever their local coal supply was to give it some consideration. I doubt they were importing West Virginia coal for their Y3 helper locomotives.
