Amtrak's Seattle Coach Yard is just few blocks south of King Street Station with Safeco Field (home of the Seattle Mariners), and CentryLink Field (formerly Seahawks Stadium) between the main train station and the yard. The yard is home to maintenance for the Amtrak Cascades Talgo trainsets, which except for the few spare cars are rarely seen in the yard except at night when on a normal schedule two trainsets are stored and serviced; the Superliners of the Empire Builder are given a same-day turn around in the yard, and the Coast Starlight is turned overnight.
The other tenants are Sounder's Bombardier BiLevels and their EMD F59PHIs that are maintained during their weekday midday layovers between making their single trips north or south (two trains make an additional round-trip) to and from Everett and Tacoma where they are stored on sidings with no maintenance provisions overnight. The Sounder trains are maintained by Amtrak (and even include their soap bottles in the bathrooms) but operated and staffed by BNSF on their tracks.
The reason the train yard gets its own page is the fact it is entirely at street level with Holgate Street running across a grade crossing right through the middle of the yard. Passerby can get excellent views and photos (using a zoom) avoiding a fence (particularly when walking by) from a completely public ROW. Lander Street beyond the southern end of the yard also provides an interesting view.
