Location & approach

The campus of the Technical University of Dortmund is located near the Dortmund West motorway junction, where the Sauerland line A45 intersects with the Ruhrschnellweg B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the south campus, the Dortmund-Dorstfeld exit on the A40 to the north campus. The university is signposted at both exits.

The S-Bahn station "Dortmund Universität" is located directly on the north campus. From there, the S-Bahn line S1 runs every 15 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. The university can also be reached by bus lines 445, 447 and 462. Timetable information can be found on the website of the Rhein-Ruhr transport association, and DSW21 also offers an interactive network map.

One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, line 2 runs every 5 minutes between Campus North and Campus South. She covers this distance in two minutes.

From Dortmund Airport you can take the AirportExpress to Dortmund Central Station in around 20 minutes and from there you can take the S-Bahn to the university. Düsseldorf Airport, which is about 60 kilometers away, offers a larger range of international flight connections and can be reached directly by S-Bahn from the university train station.
