Quote:However I have noticed your diagram for the stopping calculations; it is good that you have included one but I note that it suggests that section "e" which is the length of an overlap is sufficient distance for the train to reaccelerate to 33.33m/s, yet the table below it states that the distance for that to occur is 450m.Hello PJW,
Also you really cannot use DGR directly for stopping headway; headway is fundamentally about TIME not DISTANCE. For non-stop then these are directly related since speed is CONSTANT; for stopping then the dstance apart of the two trains constantly VARIES.
I am under the impression that accelerating to the timetabled speed of 33.33 ms-1 is not as critical as working out the time it takes for the first train to clear the overlap in order that the signals behind to clear for the second following train. I thought this is more critical as this actually limits the number of trains going through that section of the line.
Is my understanding incorrect?
Cheers
