DispositionOn display at the Wishram depot in Wishram, Washington

Built for passenger service, the locomotive was assigned to pull the Great Northern's mainline passenger trains such as the Empire Builder and Oriental Limited until being retired in December 1957 and sold the Spokane, Portland and Seattle Railway. The locomotive is now on display at the Wishram depot in Wishram, Washington.

Service history

With the intention of passenger service, 2507 was used to pull the Empire Builder and Oriental Limited and has also pulled fast mail trains and other passenger trains, but as the main passenger trains were dieselized by 1949, it was reassigned to secondary passenger trains and freight service.

Accident

No. 2507, while pulling train #27, the Fast Mail, hit a landslide near Picnic Point, south of Mukilteo, Washington in the pre-dawn hours of February 18, 1948. The engineer and fireman survived, but were both injured when the slide rolled the engine, tender and a baggage car off the track and went over the rock sea wall into Puget Sound.[1] The locomotive was eventually repaired and returned to service.

Preservation

2507 was retired in December 1957 and sold to the Spokane, Portland and Seattle Railway, as it promised a steam locomotive to the county of Klickitat, Washington steamer to display at Maryhill State Park, overlooking the Columbia River eight miles east of the SP&S division point of Wishram.[2] It was then moved to Pasco, Washington for restoration, but it didn't go through and on July 7, 2003, it was pulled by BNSF to its current home in Wishram, Washington and is displayed near the station.
