Lon also from my lousy memory of the track maps, the phone booth at McCoy was at the west end of the siding on the same side of the main as the siding. When we were at McCoy earlier this Spring, we did not look in that area for any sign of it, but rather poked around and area about midway along the siding on the opposite of the main from the siding where there is some debris and indication there once was a structure there.
I believe the phone booth as shown on the maps at Larch was on the hill overlooking the storage spur that was just east of the east leg of the wye. This storage spur would have ended about where the ATV trail heads up the hill. Jim Grigsby I believe told me there was a shack of some kind in the wye still standing untill the Hwy was built and it was demolished. Presumably a lot of things like this changed over time as to location and structures that were built after the maps were done. I believe there was also a booth at Alder Springs or at the trestle further along, not sure which or both.
