Hello everyone, <br />I have a few questions about timetable operation: <br />1.) If a train stops in unsignaled timetable territory, then a brakeman goes back one mile and has a red flag to stop any following trains. Does he also set up a torpedo, and if not, what protection is there for the train when the flagman is returning to the train but it is not moving yet? <br /> <br />2.) What does the train crew do when the train needs to back up, since the flagman needs to stay one mile back and the train will be moving faster than he can walk, and the following movement will have less distance to stop because the first train will still be backing up? <br /> <br />3.) Under what conditions would a flagman go ahead to protect the front of a train? I can't think of any senarios where this would be required, since opposing trains would stay at the siding until the train passed. <br /> <br />4.) Suppose a train is going at track speed (say seventy mph), but then drops to three miles per hour very quickly. The brakeman would drop a flare, but there probably wouldn't be enough separation between the flare and the train by the time a following movement came along for the following train to stop, but no flagman would go back far enough for a train to stop. How is this remedied? <br /> <br />5.) How does a brakeman know how far one mile back is while between mileposts. Does he count ties or what? <br /> <br />6.) On a place such as the Florida East Coast's (I believe) viaduct, which is very long but not wide enough for a flagman and a train to share, how does the flagman safely flag down a following train? <br /> <br />7.) If a flagman is walking back to flag against following movements, and he encounters one before one mile back, how does the flagman indicate to the train that there is a shorter distance to stop? <br /> <br />Any help you could provide with these would be most appreciated. <br /> <br />Most sincerely and gratefully, <br />Daniel Parks
