Mr Peters, just for you I did some very expensive research, luckily, being a quality scientist I have made sure that my experiment was repeatable, so you're welcome to give it a go yourself.Whoopee bloody do to you being a quality scienctist, I could not care if you are just the S**t house cleaner.
Spend 2x $2.70 (to ensure repeatability I did this four times) buying two paper tickets on the concourse. Put BOTH of them in the course 'valid ticket checkers' (because surely they're not 'validators' right?) use ONE to validate on board the train - it will give you what is now surely universally known as the 'justapassenger angry buzz'TM and the red light whilst saying 'already validated', don't be alarmed, you have your 'valid ticket checked, but not validated' ticket if anything goes wrong.
Sit down and enjoy the ride to someplace, wait a MINIMUM of two hours and catch the train back with the other ticket that was 'checked for validity' on the platform. Will you get a green light and a 'justapassenger pleasant ping'TM or a red light and a 'justapassenger angry buzz'TM
Let us know how you go, and we will compare your experiment with mine.
Ok So I go to Adelaide station and buy a ticket, now the machine that sells the tickets does not ask you were you want to go but only asks what kind of ticket you want, so you select the type and pay for it and now you have the ticket in your hand. Am I right so far.
Then you proceed to the barriers to go in and according to you it now validates the ticket, but I have a question for you how does the gate validator tell where you are going, see the bit about the buying the ticket. The only way that can happen is when you board a service as the driver has put in the specicfic run code etc onto the master control for that trains validators that will atomatically then set the ticket as validated as to going to Gawler or where ever it will only record that you got on a Gawler train though, it still does not know where you want to get off though, so on the way your girlfriend calls you and says I am at Salisbury so instead of going all the way to Gawler you get off at Salisbury. The system still does not know that you have got off before the ticket destination though. The ticket is valid to North Adelaide or Gawler central and you can get off anywhere in between you like. Then reboard and continue yor trip without needing another ticket if you can do it in the two hour window that is.
So how can it validate a ticket at the barriers as you could change your mind like you did and catch another train on another line, or simply go back to the drinking or whatever where you came from, the ticket is good to go anywhere though you want to travel to. So could you please explain to us all how the gate validator knows exactly where anyone wants to go and how they do it. As a Quality scientist I am eagerly awaiting your response to this, and saying micro chips implanted is not an option.
