Interesting question!
Given the linear nature of trains and the spiral nature of the vortex, it seems to me that train would automatically become more or less 'aligned' around the inner surface of the spiral.
Therefore, the rear car of any given train would only be marginally higher in the vortex than the first car and consequently the difficulty encountered 'getting off' would remain a relative constant between the front and rear cars, the exact degree being determined by the position of the train within the vortex and the surface speed thereof.
That is to say, that at entry it might be relatively easy to disembark, as indeed it might be possible to direct train out of and away from the vortex. However, as the train and it's contents descend further into the spiral, velocity increases and, at some point, extrication becomes impossible.
The scientific name for this is The PONR - The Point of No Return.
I think we already passed that point - just about the same time that connex took over.
Not all their fault, just an unfortunate confluence of the space/time continuum, as pertaining to the vortex in question.
Newton teaches us that a body in motion tends to remain in motion, and further, that without significant counter forces or 'input', that motion continues in the original direction.

Κ is a constant. Always K for some reason though C would be better.

˚ is the degrees sign and η the number of degrees around the vortex.

Methinks thou formulae be most excellently put!
However the formula explains only the current state, without any explanation of the required inputs to alter the current state to one more desirable!

A facetious mind would suggest the current state is Victoria and one more desirable might be Queensland.
They also have overcrowding problems and we are not alone in that.
I am waiting anxiously to see the effect of having no 17.13 Flinders Street - Frankston stopper around the loop in future. It becomes the 17.22 all stations direct and therefore departs just 2 minutes ahead of the 17.24 all stations via the loop but in so doing creates a gap of 12 minutes between Frankston via loop trains.
That will surely cause the overcrowding on the 17.07 and 17.19 expresses to worsen while the 17.22 runs half empty from Flinders Street and will probably have spare seats (and quite a few of them) all the way.

If they do make Frankston trains all direct to Flinders street. It will allow through routing as a single line from Werribee to Frankston and allow the every 10 min off peak service they mentioned more effective.
But driver changes would have to occur at Frankston and Werribee to avoid any more than 1 min stop at Flinders street.

Given that the government report on transport in the outer east says that 'because there is no local feeder transport, then people drive all the way to their destinations', what would be the disaster for rail if there were effective feeder bus services ? There would be so many more people trying to get onto the already packed Connex services that no one would be able to board after Dandenong for their runs into the City.

Does this justify for an express bus via Monash Fwy.?

It is a good argument, given that they cannot upgrade the rail connection in the near term. If the money has been spent on freeways, then we should make better use of them to carry people, not vehicles.

Regarding the "10-minute interpeak frequency" reported to start on the Werribee line in the mid-2009 timetable improvement, I have written to Connex who have not directly responded to my query about whether Werribee will in fact have 10 minute frequencies. However, they have provided the following interesting information:
| Quote: | The third stage of the plan will be a further timetable update in early 2009 which will focus on the frequency of services in the inter-peak period (between the morning and evening peak periods).
As you may appreciate, the specific details of the first 2009 timetable update are not yet available. However, we can confirm that the majority of lines, across the network, will receive a higher frequency of inter-peak services.
A further timetable update is also planned for late 2009, following the arrival of 18 new trains, procured by the State Government. This will provide additional capacity to further increase the number of peak period services across the network.

It has been well publicised by both the Government and Connex that there will be a 10 minute interpeak service to Werribee next year.
Views expressed by me are strictly my own, not of my friends, employer, or anyone else, unless otherwise stated.

Other than the press release I quoted, I haven't seen it mentioned before - can you point to any other sources?
Also I'm curious that I gave them the opportunity to confirm what was in their own press release but they chose not to even do that!
I thought it was a typo and they meant 15.
