Re: meteor station permit.
RB 14 covers parking or leaving a vehicle, but not waiting. I suppose that Meteor rely upon to the words "according to the instructions of -- an authorised person at that place" as allowing them to invent any rule they wish but basically they can really only tell you to move on. RB 7 prohibits touting for business without written permission so that could give them free rein to charge what they want for the permission.
Now, if you lobby the railway co directly you might get somewhere and it would be worth noting that the ticket you were handed doesnt actually match either of the above criteria so you havent broken any law, disobeyed any signage and havent refused to obey the instruction of the railway operator. If they want to continue to get you to pay up then they will have to show where you have fallen foul of the delegated authority and that might not be in their interest in the future.
