 ### About this project
 
 This repository provides a MATSim model for Switzerland's railway developed by Swiss Federal Railways (Schweizerische Bundesbahnen, SBB), Corporate Development.
+The railway model is generated by mapping GTFS train schedule data on OSM-based railway infrastructure (see `prepare/GenerateRailsimInput.java`).
+The simulation then makes use of the MATSim/railsim contrib which accounts for train-specific dynamics (for more information about railsim, see https://github.com/matsim-org/matsim-libs/tree/master/contribs/railsim).
