That is a fantastic restoration and the pictures of Skookum in the sunshine are fabulous, as is James Parfrey's video. I too (vaguely) remember the pile of parts rusting away at Snoqualmie. What was then more exciting was riding on engine 6 on several occasions, perhaps even on one that Steve Thompson was on.
And not to forget, we owe Martin Hanson on another wonderful operating locomotive, the Mt. Emily shay at Prineville, Oregon, here seen passing below the snowy summit of Oregon's Mt. Jefferson volcano
