Northwest Railway Museum, Railway museum in Snoqualmie, US.

The Northwest Railway Museum in Snoqualmie includes a heritage railway on 5.5 miles of 1889 Seattle, Lake Shore and Eastern Railway track, the 1890 Snoqualmie Depot with its semicircular north end and bay-window telegrapher's office, and a Railway History Campus with a 25,000-square-foot Train Shed and an 8,200-square-foot Conservation and Restoration Workshop.

The museum was founded in 1957 as the Puget Sound Railway Historical Association and took its current name in 1999. It preserves locomotives and equipment from the era when railways were transforming the Pacific Northwest.

The Snoqualmie depot, built in 1890, served as the gateway for Seattle vacationers coming to Snoqualmie Falls and as an outlet for local products bound for Seattle markets. Its lavish decoration reflected the holiday mood of those passengers. The depot is listed on the National Register of Historic Places, ID #74001963.

The depot in Snoqualmie and the Railway History Campus in North Bend are separate sites, so allow time to move between them. The Snoqualmie Valley Railroad runs an 11-mile round trip on tracks laid in 1889, passing the Snoqualmie Falls Generating Station. Excursions use coaches built in 1915 and earlier.

The museum operates an Education Center with a public library housing rare railway photographs, books, and technical records available for research. This collection gives visitors access to materials that are difficult to find elsewhere.
