In 1905, Southern Pacific owned and operated two adjacent roundhouses in San Francisco. These roundhouses were subsequently replaced 1906 by the Mission Bay roundhouse in San Francisco. Courtesy David Ramsey Map Collection.
Southern Pacific snow shed drawings and related information for the construction of Southern Pacific's snow sheds in the Central Sierra in the late nineteenth and early twentieth centuries. Included are changes to certain of the specifications after inspection of construction of the snow sheds. The original designs, field inspections, and modifications were conducted by Southern Pacific engineering staff headquartered at Sacramento, California.
In 1987, Southern Pacific competed in a series of corporate runs with other companies with a presence in San Francisco. Personnel from almost all of the Southern Pacific departments were members of the Southern Pacific team. Not only were the races fun for the participants, but they fostered new relationships within Southern Pacific and with those who worked for other companies in San Francisco.
Southern Pacific tie gang working with a scarifier inserter on the San Antonio Division. This mechanical device dramatically sped-up the removal of existing ties and insertion of new ties in their place.
Maintenance of the ballast layer directly below the ties is an essential part of a healthy track structure, as ballast degrades over time and becomes increasingly fouled reducing its ability to drain, provide adequate load bearing support, and withstand vertical, lateral, and longitudinal forces. Southern Pacific used specially trained crews who operated undercutter equipment to restore ballast that had become fouled.
The excavated material could either be fully discarded or screened and returned to the track, with only the finer parts of the ballast not being recycled.
The Tijuana & Tecate Railway (T&T) connected the western and eastern ends of the Southern Pacific's subsidiary, the San Diego & Arizona Eastern Railway. The T&T's trackage and facilities were located solely in Mexico, and the T&T was a subsidiary of Southern Pacific until July 1, 1970.
