Hello - There is a lot of info on this site about train travel, but rather than dig through it all I will ask you folks my direct questions:
I arrive at Heathrow on Friday Aug. 30 at 6:45 a.m. and will take the Heathrow Express to Paddington. I want to get right on a train to Abergevenny. I can see by the National Rail schedule that there are several trains scheduled, but I can't predict when I will actually arrive at Paddington so I am reluctant to buy a ticket in advance.
1. If I do buy a ticket in advance, am I assured of a seat? I definitely do not want to stand for two-plus hours on a train after that overnight flight.
2. If I don't buy a ticket in advance will I probably be able to get a ticket for the next train or might it likely be full? How can I assure having a seat on a train for which I don't buy a ticket until just before departure?
3. I will need to change trains in Newport, Wales, and some trains allow only 6 to 10 minutes for that change. Is it smart to buy a ticket with that short of a gap between arriving in Bristol and leaving on another train for Abergevenny?
