If the transports budget is the main consideration for you, then you will probably want to take the underground, Berlin’s cheapest and most economical means of transport.

The U-Bahn

The underground is one of the best in the world and is composed of two systems, one of which is the German U-Bahn.
Eighty percent of the U-Bahn is underground and spans a total of 151.7 kilometers. Because of its large scope, layout and strategic placement all around the city, you can easily find a station near every major landmark or tourist destination you wish to go to.

The U-Bahn increases the frequency of train trips during rush and peak hours – there’s a train in a station every four minutes. During regular hours, the wait becomes five minutes. On Sundays and evenings, there’s a ten-minute interval for trains. Anyway, you can also experience Berlin in a different way through the U-Bahn, as you get to see Berliners go about their business during ordinary days. In addition, this system takes you away from traffic jams and pollution outside and train schedules can help you organize your trips and itineraries better.

The S-Bahn

Besides the operator, there is no difference between the S-Bahn and the U-Bahn. The former is a smaller system which is also integrated into the U-Bahn system.
Not to worry though, as the whole Berlin metro comprised of the U-Bahn and S-Bahn are a completely unified system, so there’s no need for separate metro passes or anything.

The System as a Whole

The metro Berlin train system serves as the main means of transportation for most Berliners. It is the most economical and practical way to traverse the bustling city without running into obstacles like traffic jams or road repairs. Tourists on a budget are known to frequent Berlin’s underground lines, as it is the cheapest way to go around the city and has stations located virtually near every major destination in Berlin.

One precaution though is to bring a German dictionary with you so you can ask for direction properly if you happen to meet someone who isn’t well-versed in English. Most Berliners, as well as the staff of the Berlin metro, will be happy to help you out though, so there’s little reason to be anxious at all. You may even learn a little German in the process – and that’s a good thing, right?
