Washington State will open a new Amtrak station in Leavenworth, Washington. Icicle Station, which began construction on June 25, 2009, will open a covered platform station on September 25th. Phase 2 of the project will build a new station building and the group is accepting donations for the project.
The station code (LWA) is not currently active. I would expect this to be in the Amtrak system but the end of the week. The next station will be Stanwood station which is slated to open in November/December.
For more information regarding Icicle Station, check out the website. Perhaps someday we will get a daylight train between Seattle and Spokane and/or Seattle-Auburn-Ellensburg-Yakima-Pasco train.
