Hi Kochevnik,

I do have a few comments here...

First of all, Schoenefeld is a small airport. You should have your baggage and be through Immigration and Customs in one hour, tops. Unless your plane is very late, you will have no problem getting to the Berlin - Schoenefeld Airport station in time for the 18:50 RE (Regional Express) train. This will take you directly to the Central Station (Hauptbahnhof or Hbf), where you will have 30 minutes to change platforms and get to your ICE train, which departs at 19:48.

As I mentioned before, the train station is a 5-minute walk from the airport terminal building. Even with small children, you should be able to do it in 15 minutes!

Now, unfortunately, the 19:48 ICE train (which departs at 19:37 from the Ostbahnhof) is the last good connection of the day. It will take you directly to Bielefeld, arriving there at 22:20.

The only other connection is the 21:07 ICE from the Hauptbahnhof (20:56 from Ostbahnhof), whcih only gets you as far as Hannover. From Hannover, you then have to take two RE trains, first from Hannover to Minden, then from Minden to Bielefeld, and you don't arrive until 1:05 in the morning. (Exception: If you are arriving in Berlin on a Friday, Saturday or Sunday, that 21:07 ICE goes directly to Bielefeld.)

As far as getting from Schoenefeld to the Hauptbahnhof, there are RE trains running approx. every 30 minutes, and the trip takes approx. 30 minutes.

You didn't day exactly what date you are arriving. If you give me that info, I will give you a more exact answer, adjusted to the exact arrival date. Not all trains run daily, so this is important. If you don't want to post it here, just PM me.

I personally would not take a taxi to the Central Station, because you can run into heavy traffic, and I think the train is more certain. (Although they can also be late!) But that is my personal preference; I know some people prefer taxis. And if you take a taxi, you only have to worry about luggage once.

Those are my two cents. (Well, maybe 3 cents! )
