Summary:

This logging Mallet, one of only three standard 44" driver logging Mallets built with a tender, was built by Baldwin in 1928 for Mud Bay Logging as #8. Number 8 worked for Mud Bay near Olympia, WA until 1941 when it was sold to the Weyerhaeuser Timber Company. They put the Mallet to work as #6 on their Klamath Falls, Oregon line until 1960, by which time #6 was the last steam locomotive in use by Weyerhaeuser. After retirement, Number 6 was repainted and placed on display near Weyerhaeuser's Klamath Falls headquarters. #6 remained on display until 1965 when Weyerhaeuser donated it to the Puget Sound Railway Historical Association at Snoqualmie, WA. In 1966, #6 was moved from Klamath Falls to Auburn and then finally to Snoqualmie where it was put on display. In March of 1969, the decision was made to return #6 to service and #6 was back in steam by May of that year. #6 served the PSRHA pulling tourist trains up until the arrival of United States Plywood #11 in 1974. After 11's arrival, at least one Mallet doubleheader was held before #6 left service for work on the rear tube sheet. This rebuild, however, was never completed and #6 sat partially dismantled in the PSRHA's Niblock Yard until 1991. Today #6 is still in storage with a possible return to service planned for the future.
