Point Defiance (Tacoma)

The Point Defiance line runs along a narrow fill just above high tide on the BNSF Seattle Subdivision, placing observers within meters of mainline freight traffic. The tracks emerge from the 4,391-foot Nelson Bennett Tunnel—built in 1913 and originally double-track, narrowed to single-track in the late 1980s to accommodate taller double-stack container cars—then follow the Puget Sound shoreline south toward Titlow Beach and under the Tacoma Narrows Bridge.

Expect steady freight traffic throughout the day, with BNSF and Union Pacific (via trackage rights) combining for 30 to 40 trains in a typical 24-hour period. Because the tunnels are now single-track, trains queue on either side, giving you a natural rhythm of movements punctuated by brief lulls. The proximity to the water means you hear approaching trains well before they appear, the rail joints echoing off the cliff walls above. Public pathways and parks along the route provide legal, safe access with unobstructed sightlines in both directions—north toward Ruston and south toward the Narrows Bridge towers.

The tracks sit on rip-rap fill barely above mean high tide, separated from the Salish Sea by a few meters of driftwood-strewn shoreline. To the east, steep forested bluffs rise sharply, covered in Douglas fir, western red cedar, and Pacific madrone—the signature trees of the southern Puget Sound lowlands. Tide pools, shorebirds, and the scent of saltwater are constant companions.

The climate is maritime: cool, damp winters averaging around 40°F with frequent overcast skies, and mild summers in the mid-70s°F with long daylight hours extending past 9 PM in June. Morning fog is common in spring and fall, typically burning off by late morning. On clear days, views extend across the Sound to the Olympic Mountains. The juxtaposition of heavy mainline freight operations against this Pacific Northwest coastal setting is what makes the spot distinctive—few other BNSF mainline locations offer salt air and seabirds alongside double-stack intermodals.

This stretch of the BNSF Seattle Subdivision handles 30 to 40 trains per day, exclusively freight since November 2021 when Amtrak Cascades and Coast Starlight passenger services were permanently rerouted to the inland Point Defiance Bypass.

BNSF freight dominates the traffic mix: double-stack intermodal trains bound between Seattle/Tacoma and Portland form the backbone, supplemented by unit grain trains, manifest (mixed) freight, autorack trains carrying vehicles, and petroleum coke loads. Oil trains were once common but have declined. Coal traffic to the Centralia power plant has also decreased with the plant's phased shutdown.

Union Pacific operates freight over the line via trackage rights between Reservation (Tacoma) and Portland, adding intermodal and manifest trains to the daily count.

Typical power includes GE ES44C4s and ET44C4s on BNSF consists, with occasional SD70ACe helpers on heavier southbound trains. UP trains feature their standard AC power. The variety of train types—containers stacked two-high, grain hoppers stretching a mile, autoracks gleaming in rows—provides excellent diversity for photographers throughout the day.

The Point Defiance line offers several distinct vantage points along its shoreline routing:

Titlow Beach / Titlow Park: The most popular railfan spot on this stretch. Trains curve along the waterfront with the twin spans of the Tacoma Narrows Bridge rising in the background—an iconic Pacific Northwest railway photograph. The park provides easy access, benches, and a parking lot. Morning light works best for eastbound-facing shots; afternoon brings dramatic backlit compositions with the bridge silhouetted against the sky. A 70-200mm lens captures the classic curved train-with-bridge composition from the beach.

Tunnel Portal Area: The south portal of the Nelson Bennett Tunnel (near the Salmon Beach community) offers dramatic head-on shots of trains emerging from the 4,391-foot bore. Access is via trails from Point Defiance Park above. Midday provides the most even lighting on the portal face.

Point Ruston Waterfront: North of the tunnel, the developed waterfront promenade at Point Ruston puts you at track level for roster-style broadside shots with Puget Sound filling the background. Morning sun lights the east flanks of passing trains.

Reflections on calm water, abundant wildlife, and minimal fencing make the entire stretch exceptionally photogenic. A tripod is recommended during winter's low light. Polarizing filters help cut glare off the water on sunny days.

The Point Defiance line was completed in 1914 by the Northern Pacific Railway as a water-level alternative to the steep Prairie Line through Tacoma's Nalley Valley, which had been the railroad's original 1873 route to its western terminus. Construction required boring two tunnels: the 4,391-foot Nelson Bennett Tunnel under Point Defiance (completed 1913) and a shorter 321-foot tunnel under the ASARCO smelter in Ruston. Both were originally built as double-track bores.

In the late 1980s, successor Burlington Northern converted both tunnels to single-track to increase vertical clearance for double-stack container trains—a critical capacity improvement for Pacific Rim intermodal trade that reshaped West Coast railroading.

The line carried all Amtrak Cascades and Coast Starlight passenger traffic until December 18, 2017, when the newly constructed Point Defiance Bypass opened for passenger service. Tragically, the very first southbound Cascades run on the bypass derailed on a bridge over Interstate 5 near DuPont, killing three people. Passenger service reverted to the old shoreline route during the investigation and repairs, finally returning to the bypass permanently on November 18, 2021. The shoreline route now serves exclusively as a freight main line.

Nearby, Fort Nisqually—a reconstructed Hudson's Bay Company fur trading post from 1833, now a living history museum within Point Defiance Park—and the Tacoma Narrows Bridge (the current twin-span replacement for the infamous 1940 "Galloping Gertie" that collapsed from wind-induced oscillation) add layers of regional history within a mile of the tracks.

Point Defiance is one of the few locations in Washington State where you can photograph heavy mainline freight operations at ocean level with salt water as your backdrop. The combination of BNSF's Seattle Subdivision carrying 30-40 daily trains, the dramatic 4,391-foot Nelson Bennett Tunnel portal, and the Tacoma Narrows Bridge framing compositions creates a trifecta of railway photography subjects within a 2-mile stretch.

Unlike many Pacific Northwest rail corridors hemmed in by fences or private property, the Point Defiance shoreline offers continuous public access via parks and waterfront paths from Point Ruston south through Titlow Beach. The natural curvature of the shoreline provides both head-on and broadside angles without needing to relocate—trains curving around the coast reveal their full length before straightening for the tunnel approach.

Since November 2021, the route is freight-only, meaning the character of traffic is entirely BNSF and UP power hauling intermodal, grain, manifest, and bulk commodities. For railfans seeking pure freight action in a spectacular coastal setting without passenger train interruptions, this is one of the Pacific Northwest's premier locations.
