 gen)\, Marie Schmidt (Erasmus University Rotterdam)\, Thomas  Kneib (Unive
 rsity of G&ouml\;ttingen)\, Anita Sch&ouml\;bel (University of  G&ouml\;tt
 ingen) <br></span> <span><br>The correct identification of the source of a
  propagation process is crucial  in many research fields. As a specific ap
 plication\, we onsider source estimation  of delays in public transportati
 on networks. We propose two approaches: a  effective distance median and a
  backtracking method. The former is based on the  structurally generic eff
 ective distance-based approach for the identification of  infectious disea
 se origins\, and the latter is specifically designed for delay  propagatio
 n. We examine the performance of both methods in simulation studies  and i
 n an application to the German railway system\, and compare the results to
  a  centrality-based approach for source detection.</span>
