Spokane, Portland & Seattle Railway, recognized by its SPS reporting mark, was founded in the early 20th century to connect the Pacific Northwest with inland regions while providing both freight and passenger service across the Columbia River corridor. Famous trains such as the Empire Builder, operated jointly with partner railroads, and the Inland Empire Express continue to make Spokane, Portland & Seattle trains for sale especially popular with collectors and model railroaders focused on Pacific Northwest railroading.
SPS locomotives, passenger cars, and freight equipment remain a favorite for layouts featuring mountain rail routes, timber traffic, and classic western passenger operations. These railroad models are commonly added to model trains centered on historic Pacific Northwest rail transportation and mid-century western railroads.
