I am flying into the bremen airport and would like to know how i get from there to the train station. Also does anyone know what the cheapest way to get from bremen to berlin is... how much that would be and how i go about doing it?

DB timetable

From: Bremen Flughafen
To: Bremen

From: Bremen
To: Berlin
See if you can get one of those EUR 29,00 specials for this trip.

To expand on previous response: German railways offer two levels of discount to people booking in advance on-line: on each train a certain number of 'deep discount' tickets and a certain number of 'not quite so deep discount' tickets are allocated. (The discount fares Bremen to Berlin are 29 and 39 euros) The availability of these tickets, especially the deep discount ones, will decrease as the departure date approaches. I usually try to book rail tickets several (and at least 2) weeks in advance. So the big question is: when will you be travelling? If it's quite soon, get online to www.db.de now...

If you can, in my opinion, it's worth trying a German high-speed ICE at least once - but perhaps that my opinion because we don't have high-speed trains in Britain!
