W: Hi, can you explain the different types of train tickets to me? It's a little bit confusing.M: It's not as clear as it might be. We havefivemain ticket types, and the simplest is the Standard Single. You just turn up, buy the ticket and go.W: Can I book those in advance?M: If you book in advance, things are better. The Super Advance Single gives you a 45 percent discount if you book a fortnight in advance.W:Forty-five percentoff. That's pretty good.M: Yes, it used to be only 15 percent. If you want an even bigger discount, go for an Astra Return, which you have to reservefour weeks before your outward journey. It's 60 percentdiscount compared to standard prices, and you can return any day within six months of your outward journey.W: That's a really good deal. So, if I want to book, say, seven weeks in advance, that would get me an Astra Return?M:Yes, as long as you book 28 days or more before your trip.W: What's the Roamer? Is that something like InterRail?M: Yes. It's 247 for a month, and you can use the entire network for that period.W: So I can travel anywhere anytime on the network for a month?M: As long as there's a train going.
