After the merger with NP, GN, SP&S and Burlington, the Burlington Northern worked with the Western Pacific to try to capture some of Southern Pacific's Northwest to California traffic.

What is now the BNSF Gateway Sub was a combination of Western Pacific and BN trackage going from Keddie in California's Feather River Canyon to Klamath Falls, Oregon known as the Inside Gateway.

Here a BN-WP Pool train with Western Pacific, BN (a former SP&S Alco), Burlington, Northern Pacific and Spokane, Portland & Seattle power heads up the Highline from Keddie.
