The first of the Amtrak Cascades trainsets; the Mt. Rainier have been released and is in service between Seattle and Eugene, Oregon. I am not sure on what it’s circulation will be and I’m awaiting to see if I can use some photos from the author on the interior photos.
The Mt. Olympus trainset is next for the refurbishing program.
When all of the trainsets are completed, Talgo service to Vancouver, BC will resume though the second train to Vancouver, BC starting later this year should be Talgo equipment.
The State of Washington owns 3 of the 5 trainsets while Amtrak owns the other two sets.
