Despite all the dangers and challenges faced by early loggers in the northwest, the timber industry was quite competitive. Some timber barons, like Weyerhaeuser and St. Paul Tacoma Lumber Co., were well capitalized and could afford to invest in the latest Shay and Climax geared locomotives in building their railroads, but they were the exception. Others found ways to make do with "innovative" solutions with what I'll call DIY locomotives.
It looks like their fuel box was in the front.
I'm not sure how they built this baby, but apparently it worked and had cover for the "engineer" too. Even the Clemens Logging Company, which operated in the Chehalis area and later acquired by Weyerhaeuser, operated some "interesting" looking equipment - theirs had a T style boiler with fuel stored with the engineer. Perhaps they operated on flatter terrain.

Clearly, money capital was not the only means to success.
