Hi all,
What is the maximum speed for the trains, and what is the rate of acceleration/deceleration?
What is the allowed for dwell time at each stop? How far are the stops apart and how many are there?
How much time is allowed to unload and load at the terminal station?
Given there are no crews on the train, the turnaround time is not governed by a driver walking from one end of the train to the other, so I suppose in theory the turnaround time could be as little as 30 seconds.
If say, the max speed was 60kmh, the train would take 36 mins not including stop/start/dwell etc., but of course the train will not be running non-stop from one end of the line to the other.
After all, this is supposed to be a commuter service.
Therefore one would need around 9 trains in each direction – 18 plus one at the terminal at one end or the other (whichever).
However, the higher the speed allowed, the less number of trains required, BUT, there are other factors that may impact as well.
What say you, Tony P, have you worked out whether the equation worked out by the boffins is near the mark?
Perhaps I am off the mark given that I don’t know the factors needed to work out the equation.
Cheers
Bob in Perth

Has anyone worked out whether 20 trains (2 spares) is enough to provide a 4 minute headway over 72 km of single track?
