Would appreciate advice!
Just after 10am, I got on a train out of a central London train station, travelling to the south coast. I went to buy a ticket from the machine, but it wouldn't take either of my cards. Other people were having the same issue, so the queue for the counters got long v quickly. I only had a few minutes for the train so I ran for it and used my bank card (in the same way as journeys within the London zones) to get through the barrier. I thought it better to risk £20 fine than miss the train. I didn't think through the implications of using the card.
Once I was on the train, an inspector came. He was aware of the card issue at the station and sold me a ticket. No fine, phew.
Now I'm wondering what I should do on my return to get through the barrier? Use my train ticket? Or will there be an issue that I didn't touch out by bank card. I'll be back about 8pm. Once I'm back in London, I'll be taking the tube, .
