This shot, I believe, is a Weyerhaueser locomotive loaded with timber.
Until the Panama Canal opened on August 15, 1914, shipping Douglas fir to the East Coast had been too costly. Soon, Atlantic Coast retailers were clamoring for this new and exceptional Northwest lumber product.
Here’s an interesting Weyerhaeuser fact. In the 1930s, the company marketed this innovative new product called a Pres-to-Log. It was made from “scrap” shavings and wood fragments.
