The Northwest Railway Museum operates from Snoqualmie to North Bend and then to Snoqualmie Falls on the former Northern Pacific line. The existing line from Snoqualmie Falls to North Bend is about 5 miles. Excursions will start again on April 5th.
As a side note, Google Maps usually doesn't show the former rail lines in the Snoqualmie Valley, but if you look at Google Maps on
Lat-Long.com it does show the former NP and MILW right of ways.
And as Richard W. said, it was Snoqualmie
Falls Lumber Company, not Snoqualmie Lumber Company... :)
