The Carson & Colorado also had a turntable at Candelaria that probably lasted into the SP era. This turntable was relocated from Silver Spur on the Virginia & Truckee.
The C&C also had a turntable at Hamill -- it lasted into the 'teens and a year or so later a wye was installed at Hamill.
An early inventory says that the C&C had a "turntable spur" at Summit of Montgomery Pass. But no information if a turntable was installed there. This location was at the actual crest west of the later day SP train order office called Mount Montgomery.
Sorry I could not provide more detail dates; but, I'm traveling.
