I looked up the rail website, the tickets are £28.70 anytime, paddington to oxford. If i proceed to book, what i am getting? A booking voucher that i need to take to the station ticket counter to exchange for a proper ticket? Or i will print out a e-ticket that is good for me to board the train with?
Or is it easier to just by the ticket at the station?
On the other hand, I intend to get a oyster card to travel within london, can i use it for this journey? Is it simply tap in and tap out? I presume that is how we will ride the trains within london, tap in tap out?
And regardless of the above, the train ticket has no fixed seating. Free seating?
