On 27th August, my son aged 17 and some friends travelled to Brighton for a concert gig. They got on at Upminster and he paid on his Oyster to London Bridge and then a seperate ticket to Brighton. The concert over ran and they missed the last train home that night. Not wanting to be stuck in Brighton for nearly 6 hours with no where to stay, they were told by the bus driver that they could get a bus to one of the London airports then wait for the next train to run and go back on several trains. This meant he had to buy a bus fare back to London (which took all his money) and then use what he had left on his Oyster to get home. The trouble is he had to get to Laindon which is out of the Zones and his Oyster had covered him to West Ham. Eventually at abour 6:45 the next day he called me to pick him up after travelling nearly 6 hours to get home. An inspector stopped and asked for his ticket for which he explained what had happened and that he had paid all the way to West Ham but ran out of money to get the last leg of the journey as he had to pay for the bus. My son showed him the ticket for the previous part of the journey to prove his story. He took his details and statement. Today 8th October, I get a letter saying that" he was travelling between the two stations without paying the correct fare. That Non payment ofrail fares is an ofence which may be prosecuted in a Youh Court. In order that I may close the report from our inspector, I request that the fare of £6.40 and an administrative fee should now be paid. Payment should be for £51.40 which represents a £45.00 administration fee and £6.40 for the outstandign fare". I acknowledge that this statement is correct in that he did not have a fare for the last part of the journey. Could someone please advise me if they are obliged to supply a copy of their report? This seems excessive considering the fare. Do I have any rights to challenge this? Any help please much appreciated.
