UP SD45 3635 and three 4 axle EMDs roll their freight across the Pacific Coast (Milwaukee Road) tracks at Black River Jct. south of Seattle as the train heads toward Tacoma and on to Portland, OR. Milwaukee's Tacoma mainline joins the UP here and joint trackage will be used to Tacoma where UP will then use BN (NP) Trackage rights to reach their own line in Portland, OR.
