2013 mod 2 part A

Herewith non-stopping Calculations for 2013 paper, for comments.
I've already spotted the major clanger of using the wrong braking distance, however, that said I'm not going to re-do this bit at the moment.

Stopping calcs to do when I can get my head round what is required, although I've already signalled the layout!

One for Peter how do we work out C without knowing the station dwell time? Surely the headway for the non stopping train depends on the stopping train??

Not sure what you mean when you refer to C above. The question does not state a dwell time but asks you to state any assumptions - the implication here is that you have to identify that dwell time is an issue and state a reasonable value for that in your calculations. You are right that the overall headway will be constrained by the stopping train but the question does state that you need to work out what the headway is for a non stop train following a stopper.

Hope that helps.

What I'm trying to say is I would work out the headway for a stopping train and this would also be the same headway for a non stopping train??

I find the question pretty vague because as the slower stopping train is leaving the station the faster non-stopper will quickly be catching up, obviously the headway for a non stopper will be smaller than a stopper its how you factor them together I'm confused on. I'm not saying do the answer for me just a pointer!!
