There is currently an issue with the latest NSW Trains GTFS bundle published to AWS.
The bundle published at 5:54am has all trips sharing the same calendar, so there are 30 trains leaving at the same time.
Eg. V625 in trips.txt all have the same service_id
The bundle published at 1:30am appears OK so it is advised to use that one for now until the problem is resolved.
Thanks.
Alex
