Station 12 - Tunnel 1

Location.

WWSL 1st Subdivision
Tunnel 1 is located on WWSL's 1st Subdivision Mile Post xx.

History. The idea of a logging railroad having tunnels seems remote but there have been good reasons for loggers to build tunnels. The Olympic Peninsula had three operational logging tunnels.

  • Clemons Logging Company had a tunnel in the vicinity of Melbourne. It was built in 1922-23. [1]
  • The Port Angeles and Western (originally Olympic Spruce Railroad #1) had two tunnels - the Daley-Rankin bore and the 46 foot McFee bore built in 1917-1918. They were operational for 36 years.  [2]

Design. Tunnel 1 has two functions. First (South Portal) it is the end point of the Station 11 (OPLC) module and contains a 90 foot turntable in support of the Sawmill operations. Second (North Portal) it is the start point for the Station (13) Polson Canyon Module.
