U-Bahn Station Gleisdreieck is a crossing station, you could change the lines between U1 to U2. The satiation itself is ok, nothing really special, there not much going on inside of around the station.
Inside the station got not Imbiss (Fast food take away), but got some snacks machine around and tickets machine. At this station , it took you to my favorite Park, Park Am Gleishdreieck directly, really convenient. But I do prefer to walk from Bülowstr to there. It must enjoyable. One of the problem of this station is, when you walk around inside the park, it's kinda difficult to find the entrance, if you choose the wrong way, then you will miss it, you can still the station though, the next entrance you have to cross the whole park for this. Well, no worries, just enjoy the walk in such a beautiful park.
Beside the park, the station also close to the Deutsches Technikmuseum. It took about 5-8 mins to get there on foot. Which is quite convenient. You can also go to the Potsdamer Platz from here on foot. It took about 10-15 mims, but it will be fast an easier just stay on the train till the station Potsdamer Platz. read more
