i will be travelling to UK in jan and will be purchasing a britrail pass.
like to check
1) do i need to reserve seats on trains? if yes, how to go about doing so?
2) if question 1 is yes, for london-manchester-liverpool-edinburgh-london, which route is more popular that requires a reservation?
3) If a train is full (seats full), does the train allow standing?
4) how big is the overhead luggage rack? can it fit a 25" luggage case?
5) do the trains normally run on time?
thanks in advance!
