night train

There is a train, EN 476, to Berlin Hbf. Is that the one you mean? You would need to take bus TXL from the Hbf.

Agreeing, take the TXL bus from the Hauptbahnhof. There is no rail or U-Bahn to Tegel.

I remembered You must to cross the Street to get the bus to Teggel Airport. But is easy...

Hi Christina, When you leave Berlin Hbf., take the exit for Invalidenstraße. The TXL bus , as mentioned above, is just one of many buses across the street, where all the food vendors are.
