We are using TFL arrivals api: Mode/bus/Arrivals (with credentials).
Static TxC data we use: tfl.gov.uk/tfl/syndication/feeds/journey-planner-timetables.zip
Also checked Traveline TxC data, it is the same as by the link above.
When matching real-time data with static data we noticed that we receive arrivals for the bus #127 on Friday whereas in static TxC data the only days of operation are Saturday and Sunday.
Also on TFL website the data differs from what is in .xml file corresponding to this route:
txc file name as of 2021-05-21: tfl_51-127-_-y05-57799.xml
E.g. the only departure from the Mitcham Road / Tooting Broadway Stn is at 06:10:00 and only on Saturdays
Am I using the right source of static data of there is a better one? Or should I wait for the data to be updates and match the website?
Thanks in advance
