Branding is everything to a market. Currently, the PTV, have a serious branding issue, and needs to be fixed.
Having a mode based color-code system for respective modes, is a good idea, and is something that works well, if you do it everywhere.
The problem with the existing PTV mode-colors comes when you look at V/Line. Here, the color coding of the modes stops.
Really with V/Line, there ares three types of products each deserving of its own mode-color, and yet all share the same color, purple.
PTV in recent times, have introduced color coding of the different types transport modes operated under the PTV.
That has been done well at least for the various Suburban modes with, orange is bus, Blue is Metro train and Green is Trams.
The color-coding-of-modes stops when you reach V/Line, where all of V/Lines various modes are each colored the same purple, where I feel the V/Line network should be split into three distinct colors.
The majority of timetables should be rail only and coach only anyway. There is little need to have any combined mode timetables or other booklets.
Otherwise, you can use either a two color pattern such as stripes or a violet and purple chess board.
The counter-arguement often expressed in respect to keeping V/Line all purple is, two points.
My counter to the counter-arguements are, #1, there should be no routes having combined services. With the modern Vlocity, and the future long range V/Locity, there is no excuse in operating a bus in place of a train now days.
As for the second point above, the Warnambool line needs its own inter-city train timetable, with only that train service shown, and the same with the coach service.
With the connecting train matter, you can do exactly as what most suburban bus routes do, where it shows the times of connecting trains.
Lastly if you still need a combined timetable, you can do the table cover in a stiped pattern. The alturnate stripes can be of the respective modes shown in the timetable.
Why not introduce MyKi onto the likes of the Stoney Point to Cowes ferry?
Then again, that needs to be the focus of another campaign page.
