Re: [Model_Railroads_Of_Southern_California] Old Train Order Semaphore Signals
- The Santa Fe had two types of positions for semaphores depending on what type you are talking about. First there were train order semaphore which were in front of the station. They were two position, green and red, red was straight out or at 90 degrees form the mast and green was lowered or about 30 degrees from the mast. Since these were manually operated there was no need to worry about a power failure and the blade go to the green position. The block control semaphores were three position green up the blade parallel to the mast, yellow was 45 degrees and red was at 90 degrees to the mast. This way if there was power failure all signals would drop to stop.

- Don,BTW, in case looking at them first hand helps you, both the San Diego museum and the Santa Sue Depot ( www.santasusanadepot.org ) have operating semaphores. The Santa Sue Depot has a train order pole, a double place semaphore and a single blade semaphore, all operable. Recently put up in the case of the Santa Sue. They're SP.Cheers, PeterDon,

- Michael, Stephan and Peter - thank you assisting me in learning about
semaphores - with my knew knowledge I am even more motivated to to try
to add some to my HO layout. Thanks again, Don H. Torrance.
- Inquiry of the NMRA reference library resulted in the information that semaphores were first used in 1898. Perhaps you could learn the answers you wish by asking there.

I have looked at old prototype photos and see two basic types of
semaphores: Semaphores used by the Southern Pacific Railroad that
positioned the flag between the horizontal state and lower quadrant at
60 degrees, and semmaphores used by the Santa Fe that used three
states between the horizontal state, 45 degrees up into the upper
quadrant, and the vertical state.
Since the stop state is the horizontal state for both semmaphore
types, this trend initially seemed logical to me since there has
always been differences between railroads. However, my confusion
began when I saw some old photos along the Cajon Pass, which was
controlled by Santa Fe, that show the lower quardant type semiphore in
use at Cajon Station in 1947. It looks to me like Santa Fe may have
used both types of semaphores long their tracks.
If Santa Fe did use both tpyes of semaphores, perhaps this occured
because Santa Fe had trackage rights on some of the Southern Pacific
track up through Tahachapi, and thus had had to use Southern Pacific
semiphores. If anyone knows more about the history of these train
order semiphores signs and the types used for different railroads, I
would be interested in learning before I select a particular type to
build for my HO layout.
