Checked baggage on the Coast Starlight

[Lassen peak]

Travelling on the Coast Starlight from LA to Vancouver BC with checked baggage. The last segment of the trip is from Seattle to Vancouver is by Thruway bus. Will I need to collect my baggage in Seattle to transfer it to the bus or will it be transferred automatically?

I'm not familiar with Seattle specifically, but everywhere I've used or seen thruway you do have to collect your bags and take them to the bus.

You will need to pick up your bag in Seattle and take it to the bus.
