After arriving at Dortmund main station, take the city train S1 (departing every 20min). Because Dortmund main station is the final destination for S1, it only departures into one direction. Exit at the third station "Dortmund Universität S" [b].
The ISAS building is situated close to the motorway intersection Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best motorway exit you find on the A 45 is "Dortmund-Eichlinghofen" or on the B 1 / A 40 "Dortmund-Dorstfeld" (closer to the Campus Nord of the university area). In Both cases drive to the "Hauert" and turn into "Otto-Hahn-Str".
