Warm Springs

(Ken Rattenne Photo) It's 1986 and SP SD45T-2 9344 glides to a halt on the Decoto Line at the "west end" of Warm Springs Yard. (click photo to see another view) SP 9344 East then rolls across Mission Boulevard as it continues its way to San Jose.

By the end of 2004 this is what Warm Springs Yard looked like: Armour Yellow with shades of Rio Grande and SP patch units waiting for the call to duty.

Warm Springs yard was to the Southern Pacific what Milpitas was to the Western Pacific: Each  facility was built to serve an automtoive assembly plant. Milpitas played host to the Ford Assembly Plant and Warm Springs was home to a major General Motors plant.

Warm Springs was once a separate village, part of a collection of small villages known as Washington Township. In 1956 Warm Springs was incorprated into the new City Of Fremont along with Alvarado, Mission San Jose, Centerville and Irvington.

Seven years later, in 1963, Southern Pacific built the Warm Springs yard specifically marshal and distribute incoming and outgoing traffic to the new GM plant which opened for business that year. 

Today, Warm Springs still serves the former GM plant, now known as New United Motor Manufacturing plant (NUMMI), a joint venture between General Motors and Toyota, producing Toyota Tacoma pickup trucks, the Geo Prizm, and the Toyota Corolla. 

The yard also serves as a major collection point for freight traffic brought in by the many locals working the San Francisco Peninsula, San Jose and points south. 

Warm Springs then forwards cars to West Oakland and onto Roseville. Today, Union Pacific stations anywhere from two to four B-B road units to do local switching.

In 2005 UP closed Newhall Street Yard in San Jose, shifting the work performed there to Warm Springs and Watsonville Junction.
