As was pointed out in the extract from the paper it is not a fine, which can only be issued for CRIMINAL offense this is a CIVIL offense which is only decided at a county court not a criminal court. Nicking my stock would have been a criminal offense of stealing. The simple answer to Ernests point is you offer and pay the appropriate amount in his example £2.40 but not the penalty that is the matter that they will or will not chase through the court and that which is not enforceable without a county court judgement.
Fare evasion is a criminal offence and dealt with by a summons to a magistrates court.
