The Cascadian was an American named train of the Great Northern Railway on its route between Seattle and Spokane, Washington.

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.

Postal Service officials even proposed that the train's layover in Wenatchee should be lengthened to four hours to facilitate mail handling there.

[6][5] In its final months of operation, after a year of costs exceeding revenue by more than $100,000, the train had been reduced to just one coach and one baggage car.

These cars, originally heavyweights,[10] had recently been remodeled and streamlined by GN shops in Minneapolis and carried the markers for the Cascadians.
