UP Purchase Connects with Canadian Pacific

The Spokane International (SI), a shortline railroad, was built to connect with the Canadian Pacific Railway in 1906. The 141-mile railroad ran from its namesake city in Washington State to Eastport, Idaho, on the Canadian border. When Union Pacific acquired the SI, the route offered another important passage to link the railroad’s thriving northwest business to new opportunities in British Columbia and Alberta.

The Spokane International ALCO RS-1 locomotives were repainted in UP’s classic yellow and gray colors, but retained their SI lettering.

In 2012, Union Pacific celebrates the shared stories that have shaped our country since 1862. To mark our 150th anniversary, we invite you to explore how the nation’s largest railroad came to be and how UP continues to build America with innovation and tenacity, touching the lives of nearly every citizen.
