Welcome to the forum.
@Hadders has some very good advice on how to respond to letters from the railway about this sort of thing: for example this from

You are likely to receive a letter from the train company (or an investigation company acting on their behalf) which will probably take a few weeks to arrive saying that they have received a report, are considering prosecuting you and asking for your version of events. It is important that you engage with and reply to this letter. You might want to include the following in your reply:
- That you are sorry for what has happened
- What you have learned from the incident
- That you are keen to settle the matter without the need for court action
- Offer to pay the outstanding fare and the train company's administrative costs in dealing with the matter
Make sure your reply is short and concise, don't give a sob story - they've heard it all before. Most train companies are usually prepared to offer an administrative settlement (commonly known as an out of court settlement) for people who engage with the process and who haven't come to their attention before. There is no guarantee of this and the train company would be well within their rights to prosecute you in the magistrates court.
If you are offered a settlement the amount varies depending on the train company and circumstances but tend to be a few hundred pounds plus the outstanding fare. An out of court settlement might appear to be a fine, but it isn't and you won't have a criminal record as a result of accepting one.
But it's important for your apology and commitment not to do it again to be sincere. I may be reading rather too much into what you have told us, but I understand your position to be that
- on a number of occasions you did not pay your full fare
- on a number of occasions you were caught
- the railway now have suggested that they want to take action
- you now wish to agree an out of court settlement
If I have understood your position correctly, then my view is that the railway will see this as persistent and deliberate fare evasion, which is not suitable for dealing with out of court: they may insist that you go to court and be prosecuted. And if I have understood the facts correctly, you will be found guilty and you will be fined. So it may well be that your attempts to get an out of court settlement won't succeed. You need to prepare yourself for that being a possible outcome.
