← All TfL situations
I paid a penalty fare, but TfL is still investigating
Many people assume that once a penalty fare has been paid, the matter is finished. However, penalty fares and fare evasion investigations are separate processes. In some situations, TfL may continue reviewing a case even after a penalty fare has been issued or paid.
If you have received further correspondence from TfL after paying a penalty fare, it is important to understand exactly what stage the matter has reached.
Why TfL may still investigate after a penalty fare
A penalty fare is usually issued when a passenger is found travelling without a valid ticket but the situation is dealt with immediately by staff. However, in some cases, inspectors may still record details that are later reviewed by TfL’s investigation team.
If TfL believes the circumstances require further review, they may decide to investigate the matter separately from the penalty fare itself.

A penalty fare is a civil charge designed to resolve certain ticketing issues quickly. A prosecution, on the other hand, is a legal process where TfL alleges that an offence has been committed under railway or transport legislation.
Because these are separate processes, paying a penalty fare does not always prevent TfL from reviewing the circumstances and deciding whether to pursue further action.
Common situations where this happens
- An inspector recorded details suggesting deliberate fare evasion.
- The incident was noted alongside previous ticketing issues.
- There were questions about the ticket, Railcard, or journey being used.
- Further review of journey history raised additional concerns.
If you receive an investigation letter after paying
If TfL contacts you after the penalty fare has been paid, the focus usually shifts from the fare itself to the circumstances of the journey. This is why it is important to understand what TfL is alleging before sending a detailed response.
Practical next steps
- Check whether the letter refers to an investigation or prosecution.
- Keep any documents related to the penalty fare.
- Write down what happened while the details are still fresh.
- Do not ignore deadlines stated in any correspondence.
