I am trying to pull timetable data from
https://api.transport.nsw.gov.au/v1/gtfs/schedule/sydneytrains for Parramatta Station Platform 3.
I found the data I pulled is quite diff from anytrip.com.au

My result

You can see there are almost only T5 in anytrip but I can see T1 in timetable
the related record in stop_times.txt
"145B.1961.100.128.A.8.85117705","05:37:00","05:38:00","2150413","53","Lindfield via Central","0","0",""
in trips.txt, "WST_2c","1961.100.128","145B.1961.100.128.A.8.85117705","Lindfield","","1","766936","WST_2c","0","A8",
in routes.txt, "WST_2c","SydneyTrains","T1","Emu Plains to Berowra via City ","T1 Western Line","2","","F99D1C","FFFFFF"
May I ask what’s wrong with this T1, why it is missing in anytrip?
Thanks for your advice.

Hi @gamesover,

Are you using the calendar and calendar_dates files to filter out trips that are applicable on a given day?

Ah, it may be the reason. Thanks for your reminder.

  • calendar.txt - dates for service IDs used by each trip
  • calendar_dates.txt - exceptions for the service IDs defined in the calendar.txt file
    just one thing, after unzip the downloaded zip file, I can only see calendar.txt, but no calendar_dates.txt. Chatgpt told me it is normal, only one file is needed, either is okay.
    I assume it is normal.
now my result matches anytrip data
Thank you so much

Hi,

You’re right. Each realtime timetable bundle except for sydneytrains will include a calendar.txt file and a calendar_dates.txt file. The sydneytrains realtime timetable only includes a calendar file, so you won’t need to deal with any exceptions for that.
