[1][5][6] On 18 February 1948, while operating as a mail train, GN 2507 struck a landslide 2.5 miles (4 km) south of Mukilteo, Washington.

[2] The locomotive and a baggage car went over the rock sea wall into Puget Sound and two unoccupied coaches were derailed.

[1] It was sold to the Spokane, Portland and Seattle Railway (SP&S), who had promised a steam locomotive to the county of Klickitat, Washington to display at Maryhill State Park.

"[4] US Rep Catherine Dean May played an important role in securing the locomotive for the county, and gave a speech on the day of the handover.

[1] GN 2507 was subsequently leased to the Washington State Railroads Historical Society, but little restoration work was undertaken.
