Enter the departure and arrival stations for your trip. Typically, the most direct route to Germany will be through the Interlaken Ost train station.
Find that there is a daily departure to Berlin on a high-speed ICE or InterCity Express train from Interlaken. This route takes around 9 and a half hours to reach its destination.
Book your travel online through the SBB site and find that you may print your ticket for travel. You will need a printer and may purchase your ticket with a major credit card.
Plan ahead if you wish to purchase online, however. You will need to book your tickets in advance to take advantage of the printable ticket options offered by SBB.
Disembark in the new Hauptbahnhof or Berlin Central Station which was opened to coincide with the 2006 FIFA World Cup. This station is the centerpiece of the city's new rail scheme, which links its north-south stations, providing more comprehensive rail service throughout Germany and Europe.
Enjoy the culture of the reunified city. Berlin features many great museums, many of which are free to the public on Sundays and focus on everything from fine art to science and technology.
Climb the 285 steps to the top of the Siegessäule or Victory Column in the city's center to get an excellent overview of Berlin.
Purchase a railpass for travel between countries if you are traveling extensively throughout Europe, particularly through Germany, Switzerland and Austria. These countries have developed a cooperative railpass plan that is often more economical than travel by ticket purchase.
Know that additional fees will apply for travel on the ICE train. You will be expected to reserve a seat for travel which costs extra. In addition, if you are traveling with a railpass you will need to pay a supplement of 8 to 30 Euros for travel on the ICE.
