A GTFS feed is composed of a series of text files collected in a ZIP file. Each file models a particular aspect of transit information: stops, routes, trips, and other schedule data. The details of each file are defined in the GTFS reference.

GTFS Spezification: https://developers.google.com/transit/gtfs/reference/

  Routes are equivalent to "Lines" in public transportation systems. Routes are defined in the file routes.txt, and are made up of one or more Trips.
  A Trip represents a journey taken by a vehicle through Stops. Trips are time-specific — they are defined as a sequence of StopTimes, so a single Trip represents one journey along a transit line or route.
  A StopTime defines when a vehicle arrives at a location, how long it stays there, and when it departs.
