Location & approach

The campus of TU Dort­mund University is located close to interstate junction Dort­mund West, where the Sauerlandlinie A45 (Frankfurt-Dort­mund) crosses the Ruhrschnellweg B1/A40. The best interstate exit to take from A45 is "Dort­mund-Eichlinghofen (6)" (closer to Campus Süd), and from B1/A40 "Dort­mund-Barop (44)" (closer to Campus Nord). Signs for the uni­ver­si­ty are located at both exits. Follow the signs towards Campus-Süd.

The Department of Materials Test Engineering (WPT) is located in the "Maschinenbau III" building, which can be reached via entrance 41, where parking spaces are available. The secretariat is located on the third floor in E 03 - room 3.027.

For the approach to the TU Dort­mund University you will find the navigation on Google Maps.

Baroper Straße 303

D-44227 Dort­mund

Germany

TU Dort­mund University has its own train station ("Dort­mund Uni­ver­si­tät"). From there, suburban trains (S-Bahn) leave for Dort­mund main station ("Dort­mund Hauptbahnhof") and Düsseldorf main station via the "Düsseldorf Airport Train Station" (take S-Bahn number 1). The uni­ver­si­ty is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg. From there, Campus Süd, where the Department of Materials Test Engineering (WPT) is located, can be reached in five minutes via the H-Bahn in the direction of "Eichlinghofen" or "Campus Süd".

After leaving the H-Bahn station "Campus Süd" cross the small street and go straight forward. Take the stairs (elevator on the left side).
Turn right directly under the canopy, go approximately 200 m, the Building "Maschinenbau III" is at the end of the path.

The office is located on the third floor in E03 - room 3.027.

Dort­mund's public transport company DSW21 offers an interactive route network map with timetable information.

The AirportExpress is a fast and convenient means of transport from Dort­mund Airport (DTM) to Dort­mund Central Station, taking you there in little more than 20 minutes. From Dort­mund Central Station, you can continue to the uni­ver­si­ty campus by interurban railway (S-Bahn). A larger range of in­ter­na­tio­nal flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the uni­ver­si­ty station.

The H-Bahn is one of the hallmarks of TU Dort­mund University. There are two stations on Campus Nord. One ("Dort­mund Uni­ver­si­tät S") is directly located at the suburban train stop, which connects the uni­ver­si­ty directly with the city of Dort­mund and the rest of the Ruhr Area. Also from this station, there are connections to the "Technologiepark" and (via Campus Süd) Eichlinghofen. The other station is located at the dining hall at Campus Nord and offers a direct connection to Campus Süd every five minutes.
