That’s too bad. I’ve ridden the Cascade a couple of times between Seattle and Portland. The coaches are modern, comfortable and had AC power to run your laptop. Much better than driving if you’re going city center to city center.
On weekdays the trains run from 1/3 to 1/2 of a full load. This is because -- thanks to the timing of the slots available on the BNSF main between the cities served -- there is little train service geared to the business traveler.
But on weekends the trains sell out, sometimes weeks in advance. Amtrak has taken to selling overflow space in the bistro car to handle the load. This weekend should see full trains booked, and now there aren't any cars to run them. This what is called "bad for business".
Seattle has let their station get very run down. Also other construction has encroached on the right-of-way and taken away land formerly owned by the station so that the system can never be expanded. This is also happening to some extent in Portland although they did fix up their station and take some pride in its appearance. At one time there were 250 trains a day coming into Seattle at three stations.
