I realize this is a really dumb question, but which website do I buy train tickets in England on?? There are like 5 options. Here in the US it's just the trainline like Amtrack. I didn't know if some of these websites were like expedia (third party) or if it would be better to buy from one or the other.
Also, is the train from London to Oxenholme a ticket I need to pre-buy+ pre-book? I'm hearing stories of packed trains, etc so wasn't sure how busy that train would be. I would either be taking a Sunday afternoon/evening train or Monday morning train.
Thank you!
