The reporting mark and common initialism for the Western Pacific Railroad.

The Western Pacific Railroad was a Class I railroad that operated in the western United States, primarily running from Salt Lake City to the San Francisco Bay Area. It was famous for its Feather River Route through the Sierra Nevada mountains, offering a lower-grade alternative to rival lines. The company operated independently until it was acquired by the Union Pacific Railroad.
