In 1935, the railroad went bankrupt because of decreased freight and passenger traffic caused by the Great Depression and had to be reorganized. Western Pacific (WP) operated the California Zephyr passenger train with the Denver and Rio Grande Western Railroad and the Chicago, Burlington and Quincy Railroad. The WP handled the "Silver Lady" from Oakland, California, to Salt Lake City, Utah from 1949 to 1970. The Western Pacific owned several connecting short-line railroads. The largest was the Sacramento Northern Railway, which once reached from San Francisco to Chico, California. Others included the Tidewater Southern Railway, the Central California Traction, the Indian Valley Railroad and the Deep Creek Railroad. In December 1953, the Railroad retired its last steam locomotive from revenue service. At the end of 1970, WP operated of road and of track, not including its Sacramento Northern and Tidewater Southern subsidiaries. After the Union Pacific Corporation purchased the Western Pacific in 1982, the WP became part of a combined Union Pacific rail system: the Union Pacific Railroad, the Missouri Pacific Railroad, and the WP. The Union Pacific maintains one locomotive in its fleet, Union Pacific 1983, in the Western Pacific's traditional livery.
