Steilacoom (Puget Sound)

The BNSF Seattle Subdivision runs along the Puget Sound shoreline here, barely above the high-tide line. Sunnyside Beach Park (2509 Chambers Creek Rd) is the most accessible base: the BNSF mainline passes directly alongside the shore path, putting you at near-rail level about 20 feet from passing consists. Pay the $5 non-resident parking fee and walk the path north or south to find your angle. Trains maintain 40-60 mph through this section; a freight train 10,000-12,000 feet long takes roughly 90 seconds to pass.

About 0.6 miles north, Bridge 14 carries the mainline over Chambers Creek as it flows into Chambers Bay. The bridge is accessible via the Chambers Bay Golf Course trail network, and photographing a southbound freight crossing the direct-lift span with Puget Sound spreading out behind it is the defining shot at this location.

The active grade crossing near the Pierce County ferry ramp on Union Avenue provides another ground-level angle. The 1914 Northern Pacific depot — designed by architect Arthur Potter Merrill and still standing alongside the tracks in downtown Steilacoom — makes a compelling foreground element for southbound compositions.

The BNSF mainline at Steilacoom runs on a shelf of ballast between a low sandstone bluff and the open water of Puget Sound. At high tide the water reaches within yards of the rail; at low tide, a ribbon of pebbled beach separates the tracks from the Sound. The climate is maritime: morning marine fog is common year-round, typically burning off by 10 a.m. in summer. November through March brings persistent overcast and diffuse light — better for avoiding harsh shadows but accompanied by heavy rain.

On clear days, Mount Rainier's summit is visible to the southeast, offering a backdrop behind southbound trains. Harbor seals regularly haul out on the shoreline rocks near the tracks, and bald eagles nest in the Douglas firs on the bluff above the railway cut.

Steilacoom sits on BNSF Railway's Seattle Subdivision, the former Northern Pacific main line linking Seattle and Tacoma south toward Portland. Both BNSF and Union Pacific operate over this section — UP holds trackage rights and a UP consist was documented at milepost 15.7 in Steilacoom as recently as August 2023. BNSF runs a diverse freight mix: unit grain trains bound for Columbia River export terminals, domestic and international intermodal stacks, mixed manifest (lumber, autos, chemicals), autoracks, coal, garbage trains, and petroleum unit trains. Total freight frequency is approximately 30-40 trains per day.

Important for visitors: Amtrak Cascades and Coast Starlight no longer pass through Steilacoom. Both services were permanently rerouted to the Point Defiance Bypass on November 18, 2021. The waterfront section is now freight-only.

The nearby Joint Base Lewis-McChord (JBLM) occasionally generates military special movements — flatcars carrying Strykers, Humvees, or Bradley Fighting Vehicles — adding variety to the freight mix.

Sunnyside Beach Park (2509 Chambers Creek Rd): The shore path runs parallel to the BNSF tracks at near-rail level, offering close broadside shots. A 70-200 mm lens covers most situations. Morning light backside on northbound trains; afternoon sun from the west-southwest delivers golden side lighting on southbound movements. Summer weekends: arrive before 9 a.m. as parking ($5/non-residents) fills early.

Bridge 14 at Chambers Bay (~0.6 miles north via Chambers Bay Golf Course trails): The premier shot. Frame a southbound freight crossing the direct-lift span with Puget Sound and the Olympic Mountains behind. A 100-400 mm telephoto from the east bank of Chambers Creek or the elevated trail on the south side of the golf course works best. Late afternoon (4-7 p.m.) in summer gives warm westerly light.

Ferry dock crossing (Union Avenue): Ground-level access at the active grade crossing near the Pierce County ferry ramp. The 1914 depot facade is visible in the background. Best under overcast morning light; a 24-70 mm wide-angle captures the crossing signals, depot, and Sound in a single frame.

The tracks at Steilacoom follow a route established by the Northern Pacific Railroad in the 1870s as part of its original Pacific Northwest main line. Steilacoom is Washington's first incorporated town (1854), predating statehood by 35 years.

Bridge 14 — the Chambers Bay Railroad Bridge — is the defining historic structure. Constructed in 1914 by the American Bridge Company of New York, it was engineered by the Strauss Engineering Company of Chicago using a patent design by Joseph Strauss. A Strauss direct-lift bridge combines bascule counterweighting with a vertical lift span, and Bridge 14 is the last surviving example of this design in the United States. Joseph Strauss went on to serve as chief engineer of the Golden Gate Bridge, completed in 1937.

Also from 1914: the Northern Pacific passenger depot in downtown Steilacoom, designed by local architect Arthur Potter Merrill. It closed around 1970-1972 when Burlington Northern discontinued service. BNSF subsequently sought preservation partners to relocate the building; the Washington Trust for Historic Preservation listed it as one of Washington's most endangered historic properties.

Amtrak operated the scenic coastal route through Steilacoom until November 18, 2021, when both Cascades and Coast Starlight were permanently rerouted to the Point Defiance Bypass.

Bridge 14 is the defining element: this is the only active mainline railroad in the United States carrying a Strauss direct-lift bridge in daily revenue service. On any given weekday, 30-40 BNSF and UP freights cross a structure designed by the engineer who later became synonymous with the Golden Gate Bridge, with Puget Sound tidal flats spreading behind it.

The route also carries historical weight: the Amtrak Cascades and Coast Starlight operated this scenic coastal leg until November 2021 before being rerouted inland. The waterfront section is now exclusively freight territory — quieter, less crowded, and more focused for the serious railfan.
