And when either the member of staff doesn't believe the passenger? Or there is no member of staff selling tickets on the train so the first person they come across is a outsourced agency person who is purely there to give penalty fares?
Well judging by several months worth of using services fully within penalty fare zones every day, allow me to offer my opinion and observations:
And when either the member of staff doesn't believe the passenger?
-Well it seems most guards have no problem believing if a TVM is out of order, as there will likely be other passengers on the service reporting this, there may well have also been reports on previous services, and in some instances the guards will have seen the TVM themselves. I have seen this applied whenever a TVM has been down, indeed when I have needed to buy a ticket from my local station guards have sold me the appropriate fare on request.
Or there is no member of staff selling tickets on the train so the first person they come across is a outsourced agency person who is purely there to give penalty fares?
-This weekend just gone there were large numbers of revenue staff out and about on the Aire valley line due to the Bingley Festival taking place. Casual observation was that each check had at least one member off staff with a ticket machine available (sorry, I didn't ask if they were agency staff or Northern employees) and didn't seem to be there purely to take penalty fares. However in such an instance the first instance would be to tell them about the non-functional TVM. If they then incorrectly tried to apply a penalty fare, then complain / appeal against it.
And again I have been in a couple of situations were the TVM has been down, arrived at a revenue check having not seen the guard to buy on-board & been able to buy the appropriate ticket at the check having explained the situation.
That is of course not to say this will always be the case, in which instance I would follow the complaint / appeal route against any inappropriate fare or fine. However I have found that when a TVM has been down, reporting it to Northern seems to get either a relatively swift solution, or if that is not possible it appears on their journey check pages under station updates as a potential fault which crews & staff should be able to refer to.
This topic has a slight feel of Groundhog Day about it, popping up with almost monotonous regularity, with the same "what ifs" and discussion about possible worse case scenarios each time. All I can say, and keep on saying is that despite the original concerns raised almost 12 months ago when this scheme was initially announced, most passengers seem to be able to cope perfectly well with it, and the chaos almost gleefully predicted on here has to this date not come to pass.
