Interpretation of Stop Sequence

Hi everybody,

I’ve been working with the GTFS-R data set for Sydney Trains. When I take a look at stop_times.txt I notice a few strange features. (below is an example of a Central->Schofields weekday service)

  • Firstly, the stop_times includes stops that this service does not stop at, such as Stanmore (which has stop_id 204831)
  • Second, I know that the stop_sequence numbers indicate the order of the stops, but can’t make sense of why it jumps from 1 at Central, then to 8, 16 etc.

Would really appreciate some help.

Thanks
