Spokane, Portland and Seattle- "The Northwest's Own Railway"

Spokane, Portland and Seattle was a fan favorite in the Northwest.  It was known as "The Northwest's Own Railway" and was an Alco stronghold.  The SP and S connected Spokane and Portland via the town of Pasco, Washington.
Spokane, Portland and Seattle's trackage was a key part of successor Burlington Northern's system and is an important component of today's BNSF.  Amtrak's Portland to Spokane leg of the Empire Builder operates over BNSF's former Spokane, Portland and Seattle mainline from Portland to Spokane.
