In response to prior comment - When the new Boysen dam was built and the old one removed many years ago, the location of the dam and the level of the reservoir changed. These changes required a realignment of the railroad. The tunnel is just a vestige of the old alignment.

Anyone have any history on this? There is a tunnel shown. Was this part of the RR?
