West Berlin has a workable public transport network centred on an urban train network that makes it easy to access anywhere in the city. In the eastern areas of the city the system isn't quite so good but is slowly being invested in and improved.

Schönefeld
The main entry point for international flights to Berlin , Schönefeld airport lies 20km south-east of the city centre. There is an S-Bahn station serving the airport and trains run regularly to the city throughout the day. The dedicated airport express service runs every few minutes, taking around 30 minutes to the Hauptbahnhof, the new main central station.

Tegel
The best way to get in from Tegel is to take bus TXL, which stops at various points in the city centre, including the Hauptbahnhof (20 mins).
