As long as you’ve sent all the relevant information to the correct email address, the Northern Prosecutions team will be in touch in due course. I understand your worry and the stress of this situation; however, it’s important to remain patient.
Once all journeys made with incorrect tickets have been investigated and flagged in their system, they will most likely provide you with a total for an out-of-court settlement, along with an administrative fee. Please note that each ticket may be charged at the full fare. If you wish to have any fares reduced, you would need to provide evidence of a valid railcard.
Wishing you all the best.
