This is a chapel rail car, "Good Will", built for the Baptist church in the late 1800's. As documented in the attached link, it spent it's early years in Texas, but eventually ran on the NWP (NorthWesternPacific RR) before landing in Sonoma California in about 1938. It's about 80' long, surrounded on the 2 long sides and above by large trees, and small access roads if one was able to get it off the lot.
