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 heritage railway incorporates five miles of the line constructed in 1889 by the Seattle, Lake Shore and Eastern Railway (SLS&E), which was Seattle's response to the Northern Pacific's selecting Tacoma as their terminus. The SLS&E was later absorbed by the Northern Pacific.
