Dear everyone, <br />Hello. The recent thread "smoke signals" drove home to me how little I know about cab signals. I understand how the system works for displaying an aspect in the cab, but was hoping some of you could expound on some areas for me: <br /> <br />1.) What is the difference between ATS and ATC, and is it any different than "straight up" cab signals. Are there any other types of cab signalling systems? <br /> <br />2.) What aspects can be displayed in the cab? <br /> <br />3.) What is the proper course in acknowledging the signal? Which lever would you press? <br /> <br />4.) What is the "seal" for? <br /> <br />5.) What voltage do the systems run on? <br /> <br />6.) What makes cab signalling superior to lineside signalling? <br /> <br />7.) If cab signalling is superior, then why still have lineside signals? <br /> <br />8.) If the cab signals fail on a lineside signalled territory, the train can still proceed at 40 mph. At the same time, I believe a train can proceed in lineside signal only territory at up to 79 mph. Why would a train then be limited to 40 mph, when otherwise it could run at 79 in non cab-signal territory. <br /> <br />I realize that I'm asking a lot of questions here. If you just wanted to give me the "basic explanation," that would be fine as well. I appreciate all of your help. <br /> <br />Sincerely and gratefully, <br />Daniel Parks
