Anyway, back to topic. I think that the objective of having trains depart from consistent patterns is a worthy one - but that the real issue is making sure where customers know where to go.
Someone mentioned ticket barriers before - one of the advantages of having a single ticket barrier line is that customers going through will be able to seek information from the ticket barrier attendant (eg. you're going to have to walk within a few meters of a staff member when you enter / exit the barriers). The barriers will of course be staffed in due course.
The electronic signs at Southern Cross could be improved signficantly.
The implementation of 15/16 will be a new opportunity for customer education.
Maps would assist customers to work out what line their station is on (eg. yes, Lara is on the Wendoree Line).
I really like the approach used at many mainline stations in London where they have giant boards and have departure times for services to every individual station (eg. you find the station you are going to, and a total list of departures is provided, ordered by time). It is really useful as it gives you an idea of the frequency and when the next train is - and then you just need to work out which service it is.
Maps would help the customer work out which line the station they want is on....if it is correct.
Last time I chaeked, Lara was on the Marshall (Warrnambool) line!!!!
