My favorite signals were/are on the Chicago and North Western railroad. They used semaphores (with moving parts, unlike the Pennsy position signals you describe) with a red, yellow and green lens in the moving portion. The reason I wrote "were/are" in the above sentence is that the North Western has replaced their semaphores on the line going past my parents' house in Milwaukee with your standard "traffic light" type color signal. But I've continued to see semaphores around Chicago. I imagine it's only a matter of time before all of them are gone. Carl Blesch

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? Jishnu Mukerji
