Re: 4D Is it or isn't it

We were talking about it in the context of off peak and evening services
rather than peak ones, and of course the lines don't magically become
able to handle fewer trains outside the peak.

They also agreed that they could fit a few extra trains in the peak if
they needed to.

PTUA vision is (from memory):
Belgrave - all stations to Ringwood then Mitcham, Blackburn, Box Hill,
Camberwell, Richmond (every 10 minutes)
Lilydale - all to Box Hill then Camberwell, Richmond, City (every 10
mins)
Stopping all stations from Blackburn or Box Hill every 10 minutes with
possibly some express running between camberwell and richmond
Alamein trains act as sweepers between camberwell and richmond

When you add in the GW trains that gives you five sets of trains each
running every 10 minutes, which is a 2 minute frequency on the Burnley
group. Its (just) possible to fit all those through the loop but PTUA
policy is half through loop, half direct to Flinders.
