Western Pacific 334 is a 2-8-2 "Mikado" type steam locomotive that was built by the American Locomotive Company (ALCO) for the Western Pacific Railroad (WP) in May 1929.

Revenue service

Western Pacific 334 was constructed by the American Locomotive Company (ALCO) at Schenectady, New York in May 1929. No. 334 was one of five locomotives of the Western Pacific class MK-60-71, numbered 332-336. The Western Pacific had used the class throughout the WP's system, operating the class from Oakland, California to Salt Lake City, Utah, primarily as freight locomotives, but they did haul passenger trains up the Feather River Canyon until the larger 4-8-2 "Mountain" locomotives took over the duties in 1936. No. 334 also had one of the largest tenders on the WP. WP 334's last revenue service run was in October 1952.

Excursion service

In March 1956, the Western Pacific had reactivated No. 334 into service as they needed another steam locomotive for an excursion train through the California state. It was also used for a time in the Campbell's Soup Plant in Sacramento, California. In June 1956, No. 334 ran up to Plumas County, California and return with Western Pacific TP-29 No. 94 on an excursion train.

On June 15, 1957, No. 334 double-headed with 4-6-0 No. 94 again, when it hauled the Butte-Plumas Express between Oakland, California and Oroville, California where the excursion would get interchanged by diesel locomotives on the rest of the route to Quincy, California.

Preservation

After operating on excursion service, No. 334 was placed in storage at the Western Pacific's Oakland roundhouse until January 1967.

On March 15, 1965, No. 334 was donated to the National Maritime Association (NMA) of San Francisco, California. The NMA had then transferred ownership of the 334 to the Bay Area Electric Railway Association (BAERA).
