I have just spent a few days in Berlin. I flew in and out of Tegel Airport.
Getting to and from the Airport
Berlin and the surroundings are covered by a network of trains; the U-Bahn. S Bahn, Trams and other rail services. The airport is not. You have to get a bus to and from Tegel.
When I arrived and found this out I purchased a cheap ticket that covered my journey and once validated was valid for 120 minutes (very efficient). The guy selling me the ticket told me where to go and change to the U-Bahn. I got it wrong and got off at the wrong stop but again was guided by helpful railway staff to the correct place. Despite getting on and off a bus and a train my single journey ticket remained valid.
When looking to return I found there was a bus to the airport from the center of the city fairly near my hotel so I would not have to change buses and trains. Great, I thought, and as I was travelling light it was not a problem to walk for a few minutes to the bus stop.
This is where the rather frustrating inefficiency arose. This is a bus to an airport. People using it have cases.
There was no where to put cases!!!
The bus was full and with cases and bags in the aisles being the only place to put them it was difficult to clamber over them to get down the bus.
Generally the transport system is efficient, and straightforward to use but why not install something so simple as a luggage rack? You would lose a few seats but so what. Perhaps this inefficiency can be corrected by the powers that be.
Otherwise a good time was had and Berlin is a very interesting and developing city.
