I’ve drafted a response using inspiration from this forum, please let me know what you think:
Dear Fare Evasion Manager,
I value the opportunity you have given me to respond to the letter dated ********* with reference ************.
On Monday 13th October 2025, I was stopped by a Revenue Inspection Officer between Three Bridges and Balcombe and was unable to produce a valid ticket for the entire duration of my journey.
I offer no excuse for the above. I started my journey at Gatwick Airport using a single I purchased online through Trainline. I made a short-sighted decision when not purchasing a ticket for the entire journey that morning as the single was valid only until Three Bridges. Just after departing Three Bridges, I realised my mistake and purchased a ticket from Balcombe, the stop after, to Brighton (my final destination). In hindsight, I should have just bought a ticket from Gatwick Airport to Brighton since the cost would have been the same.
I have taken time to reflect on this decision following the investigation and I won’t undertake any action like this again. I use the railway to commute back home from university and I feel ashamed to have misused such an integral service.
I apologise profusely for my actions and for the time it has taken you to investigate and contact me. This incident shocked me and made me realise the severity of the mistake I made. I will ensure I always purchase the full correct ticket for any future journeys I take using the rail network.
I would be grateful for the opportunity to pay the full and correct fare for this journey and any administrative costs that I have created so that I may settle this matter without the need for court action.
Yours faithfully,
