The German transportation company "Deutsche Bahn" connects almost all cities and towns in Germany by railroad. There are express trains (ICE and IC) which move between major cities and regional trains which are slower but stop in smaller towns as well. In different regions, there are often additional regional train companies, which usually connect small towns and villages in Germany. The train schedules are available online and on big yellow posters on display at train stations. You can buy the tickets online, at the ticket counter (in the train station) or the ticket machine. The sooner you book a trip, the higher the chances of finding affordable tickets. In addition, there are group tickets ("Gruppenticket"), State tickets ("Länderticket") and weekend tickets ("Wochenendticket"), which are often cheaper than regular tickets. If you use the train regularly, it may be worthwhile to buy a so-called BahnCard, so that you pay less. Generally speaking, children under the age of six can ride trains free of charge.
