If the start and end of your journey cannot be determined, a maximum fare may be applied. If you believe you’ve been charged incorrectly, for example if you left the train without ending your journey or abandoned the trip altogether, you can raise a dispute in the app within 48 hours of completing the journey. Provide your journey details for us to review in the app as prompted, and we’ll adjust your fare if needed. After this time, please contact Customer Service via the online form.
