History
Built in 1909 by Alco-Brooks, the venerable No. 94 is a 4-6-0 type, shipped to WP on September 28 of that year as part of an order for 21 engines. No. 94 served her owner in unnoticed yeoman duties until the the WP completed dieselization during the early 1950s. At that time, No. 94 was pulled from active duty and stored at the Oakland Roundhouse. 

Interestingly, No. 94 was not retired, but stored servicable.  After her last shopping in 1953 she continued serving as the railroad's steam ambassador, pulling several different WP specials and excursions. The 4-6-0 even made a cameo appearance in Walt Disney's movie "Pollyanna" (starring a very young Hayley Mills), where she was temporarily relettered for the mythical Watertown & Eastern. No. 94 went from riches to rags, however, when her next assignment found her acting as a stationary boiler for Escalon Packing in Escalon, Calif. on the Tidewater Southern. She held that duty for two weeks and then it was back to Oakland. 

No. 94's last offical railroad outing was on August 22, 1960 when she powered a special passenger train between Oakland and Niles to participate in the railroad's 50th anniversary of passenger service. She was turned at Niles then placed on the head-end of the westbound California Zephyr for the return trip. No. 94 was a favorite for railfan trips and she continued in this capacity until retirement.

Museum Piece

On October 30, 1964, Western Pacific donated No. 94 to the San Francisco Maritime Museum in San Francisco, however, she never left the Oakland Roundhouse. On June 8, 1966 No. 94 was moved from the roundhouse to the Key System maintenance building for extended storage. Upon moving from the Oakland Roundhouse, No. 94 held the distinction of staying on the property longer than any  other locomotive on the roster: A whopping 57 years!

In 1978 the Western Railway Museum was successful in convincing the powers-that-be that No. 94 should be at their facility, not stored in Oakland, languishing in obscurity. On April 5, 1979, a special move to Stockton departed Oakland with GP35 3015 pulling No. 94 and a caboose. After several days (the engine still had friction bearing axles and had to move at restricted speed) WP's Grand Old Lady arrived at Rio Vista Junction (on the Sacramento Northern) at 8:00 pm on the evening of  April 9th. 

By the summer of 1979 the museum had No. 94 under steam once again, pulling short excursions on their former SN trackage. The lead photo, taken on September 1, 1985, illustrates one of the final operating days of Western Pacific's sole operating steam locomotive in action pulling a single car. 

Today, No. 94 is again in long term storage at the Western Railway Museum, in need of expensive boiler work. No. 94 has a strong and loyal fan base, hoping to see the Grand Old Lady operate again under steam.
