The Cascadian was an American named train of the Great Northern Railway on its route between Seattle and Spokane, Washington. The Cascadian was officially listed as a streamliner on August 15, 1954. The Great Northern Railway operated a daylight train between Seattle and Spokane that traversed the Cascade Mountains through the Cascade Tunnel. It then descended the eastern slopes through the Cashmere – Wenatchee apple growing region before crossing the Columbia River and climbing up to the high Columbia plain and the wheat fields of the Inland Empire. The Cascadian was a slow all-stops local train that required nine hours in either direction for the 330 miles (531 km) between Seattle and Spokane. Most passengers between these points traveled in the Empire Builder or Western Star overnight.
