On Saturday, Edmonds Amtrak Station has their annual holiday open house. If you’re interested in chatting with Sounder staff and learning about next year’s service improvements, or learning about the history of the Great Northern railroad that originally turned Seattle into a boom town, I recommend it! It’ll run from 9am-3pm.
The old freight half of the station was converted some years ago into a railroad club’s model train layout, complete with little towns and such. I don’t know if someone will be there, but during open houses they usually run model trains and talk about the history of the state.
