The Northwest Railway Museum (NRM) is a railroad museum in Snoqualmie, King County, Washington. It incorporates a heritage railway, historic depot, exhibit hall, library, and collection care center, and serves more than 130,000 visitors per year.

The SLS&E was later purchased by the Northern Pacific.

The Northwest Railway Museum maintains 18 passenger cars of various time periods, manufactured between 1881 and 1998. Most of these cars were built by either Barney and Smith, the St. Louis Car Company, or Pullman. Several of the passenger cars operate with one or both of the museum's 2 RS4 TCs and/or Northern Pacific 924 for excursion service on the Snoqualmie Valley Railroad.

The museum owns a total of 39 other railway equipment artifacts in various forms, previously operating for a wide variety of railroads. While not included as historic equipment, there is also the various pieces of equipment used to maintain the railway, some of which dates as far back as the 1950s.

The Northwest Railway Museum operates a heritage railroad called the Snoqualmie Valley Railroad. This 5 mile (8 km) route allows museum visitors to experience a train excursion aboard antique railroad coaches dating to 1915 and earlier. Trains are scheduled either Saturday, or Saturday and Sunday depending on the time of year, with chartered or special trains on various days. The railroad typically carries over 60,000 passengers per year. The railroad hosts several special events, such as the Day Out with Thomas event every July. Other events include Christmas & Halloween trains, wine tasting specials, and chartered excursions such as educational trains and corporate events.

In August 2006 the Museum dedicated the new Conservation and Restoration Center (CRC), phase one of the Railway History Center. The CRC is a place to perform repairs and restoration work on the museum's different pieces of equipment, including locomotives, passenger cars, and freight cars. It features , two full length inspection pits, and is used to perform many functions once conducted in railroad backshops. A full assortment of carpentry and machining equipment allows the museum to produce parts that have been out of production since the 1960s.
