Faced with missing my train to work I boarded anyway
In summary, you failed to purchase a ticket before you boarded (by passing a payment option) but the train was stationary.
Failure to pay [or appeal] a
PF▸ if one was issued (on the day or later) would have been an even more foolish move.
Now, looking at the Penalty Fare Rules, it says quite clearly:
Basic
4.2 (b) Passengers must be given a sufficient opportunity to buy a ticket or permit to travel
before they get on a penalty fares train or enter a compulsory ticket area.
I can see nothing about stationary trains in either the conditions of carriage or the penalty fares rules. I'm happy for someone to provide evidence to the contrary, but if you were on a Penalty Fares Train and you had sufficient chance to pay, you could have been charged a penalty fare.
To add to this, The Railways (Penalty Fares) Regulations 1994 says nothing about penalty fares not being charged on stationary (at the platform) trains.
Byelaws18. Ticketless travel in non-compulsory ticket areas
(1) In any area not designated as a compulsory ticket area, no person shall enter
any train for the purpose of travelling on the railway unless he has with him a
valid ticket entitling him to travel.
Again, I can find nothing to the contradict that this applies on a stationary train. Happy to be proved wrong.
The fact you passed an opportunity to pay means you also could have been prosecuted for a Section 5 RoRA offence, the onus is on the passenger to pay at the earliest opportunity, a queue doesn't change that fact.
The obvious get out clause here is:
The Railways (Penalty Fares) Regulations 1994
6.2.d a person acting or purporting to act on behalf of
(i)the operator of the relevant train, or
(ii)the operator of the station in question,indicated that the person in question was, or persons generally were, permitted to travel by or be present on the relevant train or, as the case may be, any preceding train without having a ticket or other authority.
Byelaw 18.3.iii
an authorised person gave him permission to travel without a
valid ticket.
So ask to board and purchase a ticket, before you actually board!
Hopefully Bignosemac will be along shortly to give us a definitive answer!
