I wasn't thinking end points but the end of that line isnt too far beyond the Pelosi Spade Backpage stop. Ends at Charles Krug Winery. There were a few dead ends I noticed while tracing the route as well.
Definitely meant railroads. Lots of these weirdo hotspots like Voodoo Donuts are on a rail line. Folllow up posts in lb were other places found near rail lines that are suspect. Rail from Oakland to Napa traces the river and passes an Air Force base and the Napa airport
