Re: Roaring Camp & Big Trees steep grades reality or a myth?

FWIW, the Heisler got a new boiler sometime while still at West Side. From the original 160 lb., I witnessed it at 175 when I rode in 1993. That'll raise tonnage a bit from the old figures.

I would tend to go with their figures. Remember too, salesmen were smart. They would rather quote a lower figure to a logger and then smugly sit by and watch
their product easily take even more than it was supposed to on a test. I knew a Weyerhauser engineer, Don Huck, whose father was a salesman for Willamette.
He pulled that stunt more than once and it got him sales.

In 1972, I ran a 3T std. gauge Heisler regularly up and down 8.6% grades in Northern CA. Even though the trains were short, it still had an easy time of it and
could be run with the cutoff shortened.
