Mike, that is what Frank told me, but Frank's memory was erratic. He remembered some things well but others were fuzzy. Frank did not work east of Gunnison very often, usually filling in for someone sick or injured. He never worked the Monarch branch. Most of the photos of K-37s on the Sargents turntable seem to all backed on.
I have learned the hard way to never say NEVER or FINAL when it comes to the D&RGW.
One of my regrets is not asking more questions of Frank Wright, Clarence Russel, Ben Snyder, Tony Matkovich, and Bill Ender. Those guys were a gold mine of 3rd division. I didn't know enough at that time to ask the questions I would ask now.
