Okay now I got ya. It ran several times, starting in the 80;s, but wasn't fully rebuilt and modified until 2015. I think 0540 is coupled to it on the same track in RH. You mentioned 0505, which I assume was a mistake since it was never on the D&S to my knowledge.
Thanks again. Will have to remember to send you a comp video when done. Am doing a Steam in the 90's series which will likely be 3 videos. One will comprise all NG including some D&S, Yosemite Mt., and C&TS. Each will have some unusual views and trains.
I am running out of vintage steam-era footage "And thats the way it is".......Walter Cronkite!!!
