Speaking of semaphores, when I was travelling by the Sunset Limited through
Arizona and New Mexico on the Southern Pacific Sunset Route, I was very
surprised to see that SP uses smaphores on most of that route.

Since I grew up in India where smaphore signals, both upper and lower
quadrant are prevelent on most branch lines and many main line even today,
it brings back memories of childhood days to see semaphore signals in use
anywhere.

Interestingly enough, the lower quadrant semaphores that are used on the
Indian Railways are two position semaphores, i.e. they have only a
stop(horizontal) and a go(45 degree down) positions. For all other aspects,
if necessary multiple semaphores are used. Are there any railroads in the
USA that uses that kind of semaphores?
