Used the wrong Railcard discount and TfL are investigating — what happens now?
This is one of the most common TfL investigation scenarios: an expired Railcard, the wrong Railcard type, no photocard, or a discount set on Oyster/contactless that didn’t apply. If you’ve received a TfL letter, it’s important to respond carefully.
Read what a TfL investigation letter meansBefore you reply
TfL is usually deciding whether to prosecute. Your written response can be used as evidence. Many people accidentally make things worse by admitting intent (even when it was a genuine mistake).

Railcard discounts can reduce fares significantly. TfL may look at how long the discount was applied and whether there is evidence it was deliberate. That’s why it’s important not to “guess” or provide a rushed explanation.
Common situations
- Railcard expired but the discount remained applied.
- Discount applied to the wrong person (e.g., borrowed Railcard).
- Wrong Railcard type for the discount set on Oyster/contactless.
- Photocard/ID issue linked to the Railcard.
- Assumed the discount “carried over” after renewal.
Can it be settled without court?
Sometimes, especially earlier in the process. It’s never guaranteed, and it can depend on the facts and your approach. If you’re aiming to avoid court, get advice before replying to TfL.
Next steps
- Check what document you’ve received (investigation letter vs SJPN/summons).
- Note any response deadline in the letter.
- Avoid sending a detailed explanation until you’ve had advice.
