A heck of an engine house!. During WW2 the Navy opened Naval Air Station Tillmook as a base for anti-submarine "blimps". Two of these huge hangars were built to house the blimps. When the NAS closed after the war the Port of Tillamook Bay Authority was created to redevelop the base. It inherited the huge hangars as well as a 5 mile rail line that connected the base to the SP at Tillamook proper. In 1990 the POTB purchased the SP branch from Hillsboro, and ran it as a through route until damage in the mountains from a storm in 2007 made it uneconomical to continue. The OCSR leases the remaining west end of the line, and while they have their principal engine house at Garibaldi, they occasionally use space inside this huge building to store and work on equipment. On Friday Polson Logging Company No. 2 picked up some a few cars at POTB and headed for Garibaldi late in the afternoon.
