Weyerhaeuser Corporation operated the line almost exclusively for twelve years. The only other railroad activity the Weyerhaeuser Corporation tolerated was the development of the Mount Rainier Scenic Railroad. The Mount Rainier Scenic Railroad was the brainchild of L. T. Tom Murray Jr., President of the Murray Pacific Corporation. The Mount Rainier Scenic was, and is today, an excursion road that shuttles passengers about seven miles on former Tacoma Eastern tracks through the foothills of Mount Rainier using antique train equipment. The primary emphasis of the Mount Rainier Scenic Railroad's historic collection is logging railroad equipment. The Mount Rainier Scenic Railroad has grown since 1980 from being a one-locomotive railroad to the world's only rail heritage group with one of each type of logging locomotive in working order.
