I have been sketching a few of the remaining Southern Pacific water towers in California but I had yet to add a control tower to my sketchbook.
There are about nine Southern Pacific interlocking control towers still in existence in California and 16 are still in existence on the former SP system. These control towers where once ubiquitous on America’s railroads at busy junctions or rail crossings. Interlocking control towers centralized a group of signals (semaphore and lights) that were controlled by an operator to control the rail traffic by communicating different orders: proceed, caution, or stop. Think of it like a traffic signal for trains.
The Santa Clara Southern Pacific Interlocking Control Tower was built by SP in 1926 and put into service in 1927. The tower was in continuous use for 66 years at this very busy junction of the Coast Line and the Western Division. In the 66 years of operation, many trains, both passenger and freight, passed by. The famed Coast Daylight sped by the tower, stopping to take on passengers in San Jose.
The tower was in use until July 17, 1993 when the control of all switches and signals were moved to a centralized control center in San Jose.
Santa Clara is a busy junction where the Coast Line and the Western Division meet. It is busy today with both passenger and freight traffic. The passenger trains that stop or pass this way are Caltrain, Capital Corridor, the Altamonte Corridor Express (ACE), and the Coast Starlight. Four main line track pass Santa Clara, tracks to the northeast are used by Union Pacific for freight. The other three train a primarily used for passenger service with some routes turning off here to head north, on the east side of the Bay, towards Oakland (the Western Division).
Sketcher’s Folly: Oops I did it again. I made a sketching mistake. In my sketch of the California Theatre in Dunsmuir I left out an “I” and now I made the egregious mistake of misspelling the county of my birth: Santa Clara. What next? Misspelling my own name?! Well at least I’m making new mistakes!
