👉 The "Pacific Trail" refers to a major rail route across the Pacific Ocean, connecting Australia with the United States via a series of points including Hawaii, Oregon, California, Washington, British Columbia, and Canada's Northwest Territories. It started in 1869 as the Southern Pacific Railroad and was later extended by Union Pacific Railroad. The name "Pacific Trail" is often used to refer to this route, referring specifically to its southern terminus at the mouth of the Panama Canal or just before it crosses into the United States.
