Signaling on the CB&Q is a large subject. Some of the first of course was train orders for dark territory. Then with stations a system of lock block was used where the train order signal was used. The operators would use that signal and not clear it until communications with the next station that the block was clear. With automatic block signaling came to the East End(Aurora to Chicago) the lower Quad semaphores as technology improved and Color lights in a triangle(4/26) were put in the lower quads were refurbished and moved west and or north. This system was used over the years with the different style of signals. So over the years you can find several signal styles used on the same territory as the technology got more improved. Early Auto train Stop was tested at various locations as well. My earliest article is dated Dec. 1908. Another increase was the remote control of signals which was used to save labor by cutting out towers and or stations. At one time the Check Block System ran all the way from Chicago to Denver
Railway Signaling 2/28 is the best article about ABS Chicago to Denver. Just about every style was used on the Q and one of the major efforts was Automatic interlockings at remote locations with low traffic(branchlines) A signaling article would be a giant Bulletin because of all the ground to cover. You would also need all five of the rule books as rules changed over the years.

TT&TO were used the entire life of the line, but by the 1940s, no operators were still around to copy orders and man the train order boards because traffic was down to one mixed train daily except Sunday. I suspect that most of the branch lines were dark.
Somebody in the BRHS was working on a Bulletin article on signaling, but I haven't heard anything about it for years. It would be a great service to Q modelers to make that material available.

Looking through my books I see a mixture of lower quadrant semaphores in the early pictures and some searchlights in the later pictures with some three light verticals scattered about. Lower quadrant semaphores appear to be the type used for train order signals at stations. Also I would like to see some schedules with signaling rules on the branch lines, particularly on the K&W line from Alexandra MO. -- Don Bowen --AD0NB-- ------------------------------------ Posted by: Don <don.bowen@earthlink.net> ------------------------------------ ------------------------------------ Yahoo Groups Links __._,_.___ Posted by: STEVEN HOLDING <sholding@sbcglobal.net> __,_._,___ |
