Hello Peter (the other),
Thank you for your reply to my questions.
In addition to your point with respect to my first question, signalling the layout for stopping trains to proceed at the speed of 100 km/h when the permitted speed is 120 km/h does give drivers the chance to catch up on delays if they have to. So I agree that for Following Stopping at 4 minutes, the speed to use should be 100 km/h.
For my second question, I think it would be sensible to put in a contingency of 20% for the Stopping headway of 4 minutes giving a technical headway of 200 secs. Unless advised otherwise that there is no need for this, I intend to do so for the exams.
Thank you once again for setting up this very excellent forum! Without it, there is absolutely no chance for me to prepare for the exams half a world away!
Good night
Cheers
