As far as I can tell, I show up at the train station on the day I want to depart to my next destination and simply hop on the first train that I want to take, making all the necessary transfers along the way. (Clearly, I'm leaving out a lot of steps here. I wrote a Cliff's Notes version of a travel day.)
I guess the thing I'm questioning is that I'm sure certain trains are fully booked on occasion with travelers who purchased point-to-point tickets ahead of time. What does this mean for a Britrail pass rider? Is using a Britrail pass kind of like flying stand-by--you could get "bumped" if train is full?
One more semi-related question: RS mentions both the Britrail and National Rail websites for train route inquiries. Route-planning wise, is one site better than the other OR provide different information over the other?
Please bear with all my elementary questions!
